A Couple Things About Electronics & CB's (also applies to other transceivers and receivers)

Back to the table of contents
*Electrical current travels from negative to positive.
*Current is the flow or travel of electricity.
*Voltage is the storage of electricity; the amount it has
that can flow as current.
*Voltage is in the power source, but drops through the
circuit across resistances or loads.
*The circuit voltage always adds up to the supply voltage in
series circuits.
*In parallel circuits every item has full supply voltage.
*Parallel circuit items operate independently of each other,
while all must function in a series circuit.
*Resistance and current are inversely proportional, that is,
the more resistance there is in a circuit the less circuit can
flow through it.
*Resistance is expressed in ohms.
*The larger a resistance the more voltage will drop across it
in a series circuit.
*Current times voltage makes wattage (Ohm's law).
*Current times resistance equals voltage (Ohm's law).
*When voltage increases, capacitance tries to hold it down.
*When voltage decreases, capacitance tries to hold it up.
*The voltmeter measures across resistances or batteries.
*The ammeter must be in series with the circuit.
*The ohmmeter must be used with the circuit power off.
*The 1/1000 part of an amp of current is called a milliamp.
*The 1/,000,000 part of an amp is a microamp.
*A thousand ohms is a kilohm. A million ohms is a megohm.
*Alternating current, AC, flows first in one direction and
then in the opposite. The speed of this is expressed in Hz
(Hertz). Kilo means thousands of Hz and mega means millions of
Hz.
*All other things being equal the higher the speed of alter-
nations in Hz the farther the radio carrier waves will travel.
*Resistor color codes:
Black = 0 Green = 5
Brown = 1 Blue = 6
Red = 2 Violet = 7
Orange = 3 Grey = 8
Yellow = 4 White = 9
*A resistor limits either AC or DC, that is, any kind of
current. The higher the ohms the more it resists current, and
the more voltage it can develop across itself in a series
circuit.
*A coil passes DC but limits AC proportionate to frequency.
The lower the frequency of AC the better the current flow. A
coil develops magnetism when a current travels through it.
*A transformer is a combination of coils. The primary coil
induces a voltage into the secondaries, dependent upon number of
turns. A transformer can only pass AC or pulsating DC (voice
signals) from primary to secondary.
*A capacitor stores electricity on metal plates that are
slightly separated. It passes AC, but not DC. The higher the
frequency of AC the better the capacitor passes it.
*A switch makes or breaks contact in electrical circuits.
*A diode changes AC to DC. The end with the band is
positive.
*A transistor is a current-amplifying device. Weak currents
in the base-emitter circuit affect strong currents in the base-
collector circuit. NPN types have positive collector voltage.
PNP types have negative collector voltage applied.
*Tubes are voltage-amplifying devices. Small voltage
variations on the control grid affect large voltage variations on
the plate load circuit. In tubes, electrons must travel through
space.
*Relays are electromagnets with contacts that connect and
disconnect circuits. Usually a mike button connects the electro-
magnet in the relay.
*Speakers convert electrical pulses of audio frequency to
sound by magnetic interaction between the voice coil and the
permanent magnet. The cone produces the audible sound.
*Microphones convert voice vibrations to electrical pulses by
disturbing magnetism or by bending a crystal or by changing
resistance in a carbon mike.
*A crystal vibrates when current is applied. The size of the
crystal determines the rate of vibration and the nature of the
resulting carrier creation.
*The carrier is the high-frequency AC of a radio signal that
takes the intelligence from transmitter to receiver.
*The frequency of the carrier determines what channel it will
be on.
*Modulation is the process of allowing voice current pulses
to shape the size of the carrier or it's amplitude.
*Applying current to a crystal will cause it to bend. If the
current is taken away the crystal will relax and give off a
current in the opposite direction.
*A transistor can be used to form an oscillator since the
crystal first feeds back energy to the base and stops the action,
then sends current the opposite way. The created AC signal is
then amplified by the transistor(s).
*A tuning coil loads up the AC signal and connects it between
antenna and ground.
*If the antenna is too short, a coil can effectively lengthen
it.
*A receiver must detect the signal. By this we mean that it
cuts off either the positive or negative half of the wave,
leaving the other half with it's modulation.
*The modulation is exactly the same on each half of the
carrier as put on at the transmitter.
*A stage is a transistor, or it could be a tube, and it's
associated parts.
*Coupling capacitors connect the signal from transistor to
transistor without passing battery DC. Bypass capacitors take
signals away from other components to prevent oscillation or
interference.
*In audio frequency circuits, large-value capacitors bypass
the signal past the emitter with protective resistors.
*The output transformer matches the impedance between the
transistor collector and the speaker coil.
*Impedance is the resistance that a coil, or capacitor, or
even a transmission line offers to AC. It will not measure as
high with an ohmmeter.
*Most transceivers and receivers other than some hand-held
units make use of superheterodyne technology. Signals are mixed,
and tuning selects either the addition or subtraction of these
frequencies.
*The master oscillator is either a PLL or synthesizer and
furnishes a mixing frequency for both transmitter and receiver.
In CB this frequency is often above the CB band.
*There is also a transmitter oscillator that mixes with the
master oscillator frequency to produce the carrier near the
transmitting MHZ.
*Many CB sets have a receiver oscillator for double
conversion of signal, making two intermediate frequencies.
*Most of the receiver signal amplification for CB takes place
at a low frequency, often 455 KHz.
*The audio stage does double duty: it amplifies the detected
signal for the speaker, and it builds up the mike signal and
modulates the carrier during transmit.
*The squelch detects a signal sample, if any. If none, it
either removes positive bias from the audio and kills the
receiver from noise broadcast, or injects negative bias to do the
same. When signals are present the bias is changed so the audio
can amplify the signal.
*Single-sideband (SSB) broadcasts remove the main carrier at
the transmitter and side of one sideband. Some carriers travel
in the broadcasting sideband to make it tunable at the receiver.
The pitch of the voice broadcasting determines deviation from
channel frequency. There is no carrier between sounds.
*SSB requires reinsertion of the carrier lost at the
transmitter for intelligible listening. It does not have to be
at the same frequency, but the reinserted frequency plus mixer
frequency difference must add up to the channel frequency being
listened to.
*Antennas tune just as coils do. The coil is expressed in
frequency, but the antenna in wavelength. If the wavelength of
the antenna matches the wavelength of the channel, the standing
wave ratio (SWR) will be very low, and good reception and
transmission will result.
*To be legal for citizens band, the frequency must be
within +/- .005 percent or 1,350 Hz of assigned channel.
*Frequency modulation, FM, carries the velocity of sound as
frequency bunchings and spreadings. The pitch of the sound rides
along as sidebands.
*FM is modulated in modern equipment by voltages impressed on
a varactor - a voltage-sensitive capacitive diode.
*FM is detected by voltage variations through loads by diode
difference conduction depending upon whether the tuned circuit
input signal is on frequency or not.
*Class C amplification is such that half of every alternation
is lost. A class C amplifier is biased so that the collector or
plate current flow is only during a portion of each cycle or Hz.
*A class C amplifier is biased so that the collector or plate
current flow is continuous.
 

Air-to-Ground Telephone

Back to the table of contents
This service is used on private aircraft. Transmissions are
in FM and the ground stations repeat the airborne half of the
conversation, and transmit a continuous tone when idle. From one
to four channels are assigned in a particular area.
For the 800 MHz air-to-ground telephone the transmissions are
in AM. Channels are spaced 6 kHz apart and a specific block of
29 channels is assigned to each geographical area. Ground
frequencies are 45 MHz lower and do not echo the airborne half of
the conversation like the 454/459 MHz ones.
 

Antennas

Back to the table of contents
Remember to get your antenna as far away from interference as
possible. If you have to, you can mount your antenna inside your
attic if the roof is made of wood or something which won't
interfere with the radio signal.
There is a theoretical formula for increasing range. Measuring
from the ground to the bottom of the antenna itself, doubling the
height of the antenna above the ground increases range by 50%.
Four times higher doubles the range.

Types of antennas:
Wick. Dipping a piece of string in oil will absorb a
little of it. Same principle with a piece of wire - it
will absorb a little of the radio waves around it. The
telescoping antennas which come with some scanners are
this type.

Wideband. This antenna is made to be somewhat
efficient at all frequencies. But it also brings in
things which you might not want - like interference. A
discone is a wideband antenna (see below).

Multiband. Different elements make up this type of
antenna corresponding to the frequencies which you want
to receive.

Monoband. An antenna designed to match one frequency
or range of frequencies. Not efficient on others.

1/4 Wave Ground Plane - Consists of a single band
vertically polarized antenna which offers about 3 dB of gain
in a fairly narrow frequency range. Benefits are its low
cost and small size. The ground plane isolates the antenna
from having to be coupled to earth ground at a specific
multiple of the wavelength, by simulating ground with the
radially mounted elements around the bottom. A car mounted
antenna is typically a 1/4 wave which uses the body of the
car for its ground plane. There are some versions which have
several vertical elements (like the Radio Shack all-band with
three) but each vertical element will only be resonant in one
band. While it will receive signals in all bands, it will
only be efficient in the 3 bands which the vertical elements
are cut to resonate at. Radio Shack's all-band is a good
antenna if you have a limited number of bands you listen to.
(Note: I have this antenna and it seems to get fairly good
response over the whole range).

Discone antenna - A relative of the 1/4 wave ground plane
antenna offering wide frequency bandwidth. It has 0 dB of
gain on frequencies from about 120-1300 MHz, and with a
vertical element on top, it is usable down to about 30 MHz.
Gain is achieved by compressing the radiation pattern into a
donut shape with little of the signal radiating upwards or
downwards, concentrating the pattern perpendicular to the
vertical axis of the antenna. Its called a discone because
it is comprised of two parts - the disc, a group of elements
parallel to the ground around the top; and the cone, the
diagonal radial elements around the bottom. These could be
made from a solid metal disc and a cone-shaped sheet metal
radial, and perform the same, but the wind loading would be
increased. The Diamond D130J and the Sigma SE1300 are good
discones for general purpose scanning. (Note: Mike Diaz,
who's text I got these antenna descriptions from, notes that
he has had experience with the Radio Shack discone antenna at
home, and has shown that it is not a very good implementation
of the discone design, and should be avoided. He says that
it is too fragile and does not work below 100 MHz.)

1/2 Wave Dipole antenna - This is also a single band
antenna which offers 2 dB of gain in a relatively narrow
frequency range. The dipole antenna is the standard against
which gain is measured on all antennas, and it is twice as
long as a 1/4 wave antenna. This antenna has balanced signal
and round sides, which means that the coax feed is in the
center of the antenna. The center conductor is hooked to the
top half and the shield connects to the lower half. It
requires a balun to connect it to coax cable, although there
are feed techniques which can do the job of matching the
antenna to the 50 ohm coax. It is fairly large for the
frequency it's tuned to, and like the ground plane antenna,
it isolates your antenna from having to be coupled to earth
ground at a specific multiple of the wavelength, by
simulating ground with the lower half of the antenna. The
dipole can be oriented either vertically or horizontally.

Yagi beam antenna - This antenna was named after it's
inventors Mr. Yagi and Mr. Uda. The Yagi-Uda parasitic array
is another single band antenna. It offers 10-20 dB of gain
and 10-30 dB of front-to-back isolation in a relatively
narrow frequency range. It is a group of dipoles all the
same length, connected to a boom, to hold them a specific
distance apart. It offers excellent gain, and front-to-back
isolation, and a narrow beam width which it will receive
from. The gain is determined by how many elements are used
as directors, and is achieved by limiting how many directions
a signal can be received from. Like a magnifying glass
focusing the sun, the smaller the spot the hotter it gets.
The most useful feature of a beam antenna, is that it can be
rotated to null out a signal you do not want or maximizing
the one that you do want. You will need a rotor to point it
in the right direction; if you want to listen in more than
one direction. The downside is that it will only have gain
in a narrow frequency range of about +/-1% of the center
frequency, which would be beneficial in a dense signal
environment to attenuate those intermod producing signals
that you do not want, or if you only listen on one band. It
is most commonly used by commercial and amateur operators,
since it is an inexpensive and very efficient type of antenna
for single band point-to-point communication in the VHF/UHF
range.

Log Periodic beam antenna - The Logarithmically Periodic
Dipole Array is a beam antenna optimized for wide frequency
bandwidth. It offers 5-15 dB of gain with a moderate 10-15
dB of front-to back ratio; the beam width is fairly wide when
compared to a Yagi. It is a group of dipoles of decreasing
size (with the longest in back and the smallest in front),
connected to a boom, to hold them a specific distance apart.
The tapering of the elements is what gives it the wide
frequency range, by always providing an element which
resonates near the frequency that you're operating on. It is
most commonly used in TV antennas, where operation on many
frequencies is required. The downside is that this antenna
can be fairly large for a VHF/UHF antenna. There are
commercial versions available which provide general coverage.
Create Labs makes two models for $200-350. EEB and Ham Radio
Outlet both have them in their catalogs.

TV antennas - A TV antenna is not a very good scanner
antenna because it is optimized only for the TV bands. If
you look closely at a TV antenna you will notice that the
taper of the elements is not uniform. There will be several
long ones (channels 2-6 at 54-88 MHz) then several medium
long ones, usually interspersed with the long ones (channels
7-13 at 175-216 MHz), and then a bunch of short ones, all
the same length (UHF 470-812 MHz). The missing elements are
for the frequencies which a scanner user wants, but are not
in the TV band, so they are not included in the design. If
the frequencies which you do listen to are close to the TV
bands it may be for you but you must re-orient the TV
antenna to vertical polarization. Another problem is that
the UHF elements on a TV antenna are always a Yagi design.
The reception range that they advertise is only on one
channel (probably around channel 35 at 600 MHz) and the gain
falls off the farther you get from that center channel. You
will never see a gain Vs frequency plot of any TV antenna
from the manufacturer. If you want to use a wide band UHF
TV antenna. Try a 4-bay bow tie which has about 6 dB of
gain, a 15 dB front-to-back ratio and resonates across a
wide frequency range. And again, the antenna needs to be
re-oriented to vertical polarization. Some people have
TV antennas for their scanners and have reported some
use.

If you have a telescoping antenna for your scanner try
collapsing a couple sections for better high-frequency
performance (Radio Shack's Part Number 20-006 works great). The
shorter it is the better it may receive higher frequencies. You
can also apply this to your car's collapsible antenna if you have
your scanner hooked up to it. Here's a general guide...

25-136 Mhz -----------------==------------ (full length)
138-174 Mhz -----------------==----- (extend only top four
sections)
220-1296 Mhz --==---------- (extend only lower 1 to 3
sections)

To get a quick fix on frequency ranges for mobile units of
any type use these tips:
The antennas which have 60 to 100 inch-high whips or 35 inch-
high whips with a 5 inch coil at the bottom (these look kind of
like CB antennas) are the VHF low-band antennas.
The ones which have an 18 inch-high whip or 40 inch-high whip
with a 3 inch coil at the bottom (these might look like CB
antennas, too - don't confuse these antennas with similar VHF-Low
antennas) are VHF high-band antennas.
UHF antennas have a 6 inch-high whip, a 32 inch-high whip
with a 3 inch coil in the middle, or a 35 inch-high whip that has
a grey or black plastic band in the middle of it.
The ones which look like a cellular telephone antenna; an 18
inch-high whip with a coil in the middle (coil may or may not be
exposed, if exposed it may look like a pig tail) or antennas
consisting of a 3 inch-high whip are 800 MHz antennas.
You can also get some radio trade magazines, make up a
company name and mark lots of those little product information
cards concerning antennas and radios. Make sure you put a
company name or they may not send you as many advertisements.
When you get the company's advertisements study the antenna
and radio types. Before long you'll be recognizing frequency
ranges of antennas and radios you see around. Even if an antenna
or radio is not made by a company you have become familiar with
you still may be able to recognize frequency ranges; after all -
there's only so many ways to make a radio and so many ways to
make an antenna.

Back to the table of contents
- On 2-Meter (144-148 MHz), repeater inputs are .6 MHz below
outputs.
- On 1.25-Meters (222-225 MHz), repeater inputs are 1.6 MHz below
outputs. (inputs are between 222.32-223.28, outputs are
223.92-224.98, and simplex operation is between 223.42-223.90)
- On 70-CM (420-450 MHz), repeater inputs are 5 MHz below outputs.
- On 33-CM (902-928 MHz), repeater inputs are 12 MHz below
outputs.
- On 23-CM (1240-1340 MHz), repeater inputs are 20 MHz below
outputs. (inputs are between 1270-1276, outputs are 1282-1288,
and simplex operation is between 1294-1295)
- A burst of tones heard on some repeaters are what is required
by the operator to access some repeaters.
- Some repeaters have a courtesy beeper which leaves a space
between conversations for new stations to break in. If a
station broadcasts before the tone sounds, the repeater may
shut down temporarily to indicate a violation.
- Amateur radio also uses digipeaters (see Digipeaters section
for more info).

Aviation

Back to the table of contents
Air traffic control towers (ATC) are responsible for the air
traffic within 55 nautical miles of their respective towers.
Ground Control directs and controls the ground traffic which
includes ALL vehicles and planes on the ground. It is found in
the top of the tower and most of the time has a clear view of the
ground traffic.
The first thing a pilot does is files a flight plan to taxi
to the runway which Air Traffic is currently using. Then
when conditions allow, the controller directs the aircraft to
proceed via the taxi ways to the runway where it would then be
instructions to take off.
The controller in the tower has responsibility for aircraft
out to 10 nautical miles after which he hands the responsibility
to the controller who has responsibility from 10 to 55 nautical
miles. This latter controller is usually located in the base of
the tower.
After 55 nautical miles the aircraft is handed off to another
tower along with the pilot's flight plan.
The opposite happens when a plane approaches.

Radar Service Terminated - the controller is no longer
providing traffic advisory or separation service for the
aircraft. This could be because the controller is too busy to
handle some types of traffic, was unable to "hand off" the
traffic to another controller, or has instructed the pilot to
contact a facility which does not have radar (most towers do not
have radar). You will not normally hear "radar service
terminated" with airline traffic on IFR flight plans. It is
common with VFR flights that are using "flight following"
services.
MODE-C, or Transponder "Squawk" (military version is called
IFF, see definitions). An airport's radar is a two part antenna
system; the radar antenna and an interrogator. The radar tells
the controller in the tower that there is a plane there but it
doesn't say which plane it is. The interrogator sends a signal,
which the plane receives and responds to with a transponder
"squawk" which identifies the plane. The controller's radar
screen then displays the ID beside the radar contact.
The "squawk" consists of a 4 digit octal code assigned for
that aircraft for that flight by the controller or before the
flight when receiving clearance. Mode-C also contains the
aircraft's pressure altitude from an onboard altitude encoder.
ATC computers use the four digit code to determine and
display the aircraft callsign and altitude (corrected for the
local altimeter setting). The computers can also display the
ground speed of the aircraft by tracking the target and doing the
time and distance calculations; the transponder does not send
speed info to the computer.
When you hear news stories about FAA ATC computers going
down, it usually means they can't use the transponder replies for
information and have to deal with raw radar, if they have it.
 

Cellular Telephone

Back to the table of contents
The cellular telephone system was given its first US test in
Chicago in 1978 and is named for the unit "cells" into which it
divides an area. Each cell has a radius of around 1.5 to 2.4
kilometers (1 to 2.5 miles).
Remember, it is illegal to monitor any kind of cellular
communications.

The mobile units (the cellular telephone itself) transmit 45
MHz below the base (824.040-848.970) and are usually repeated by
the base. Channels are 30 kHz apart and channels 800-832 are
also identified as Channels 991-1023. Narrow band FM is usually
used for cellular. (see Frequency Allocations for more info on
channel designations)

The below is reprinted from a textfile called SCANHINT.TXT
by an unknown author.

Here is a method of determining which freqs are used in a
cellular system, and which ones are in what cells. If the system
uses OMNICELLS, as most do, you can readily find all the channels
in a cell if you know just one of them, using tables constructed
with the instructions below.

Cellular frequencies are assigned by channel number, and for
all channel numbers, in both wireline and non-wireline systems,
the formula is:

Transmit Freq = (channel number x .030 MHZ) + 870 MHZ
Receive Freq = (channel number x .030 MHz) + 825 MHz

"Band A" (one of the two blocks) uses channels 1 - 333. To
construct a table showing frequency by cells, use ch 333 as the
top left corner of a table. The next entry to the right of
ch 333 is 332, the next is 331, etc., down to ch 313. Enter
ch 312 underneath 333, 311 under 332, etc. Each channel across
the top row is the 1st chan in each CELL of the system; each
channel DOWN from the column from the first channel is the
next freq assigned to that Cell. You may have noted that each
channel down is 21 channels lower in number. Usually the data
channel used is the highest numbered channel in a cell.

"Band B" uses channels from 334 to 666. Construct your table
in a similar way, with ch 334 in the upper left corner, 335 the
next entry to the right. The data channel should be the lowest
numbered channel in each cell this time.

For more info on trunking see that section below.

Also note that many scanners will receive cellular even if it
is locked out or deleted. For example, on a Bearcat Uniden
BC-200 XLT you just add the intermediate freq of 21.7 MHz to the
frequency that you want to monitor. Even if a scanner receives
cellular normally, it may also receive them above or below what
is considered the normal range.
 

Checking AM/FM Antennas

Back to the table of contents
1) If center pin of antenna lead shows resistance, replace
the antenna lead.
2) If there is any current passing from antenna to fender,
look for a shorted antenna.
3) If the antenna shielding conducts any current, replace the
antenna. Resistance here should be zero.
 

Citizen Band (CB)

Special purpose channels
Channel 3 - Unofficial Marine channel
Channel 9 - Emergency and sometimes motorist info and
assistance, monitored in some parts of the country by REACT.
Channel 11 - Formerly the official calling channel
Channel 13 - Unofficial Marine channel and used by RV's as
a monitor channel.
Channel 14 - Is often used by walkie-talkies.
Channel 16 - Old SSB channel (23 channel days)
Channel 18 - Old SSB channel (23 channel days)
Channel 19 - The trucker's channel and highway channel
Channel 23 - Was set up in the old FCC rules as being a
paging channel so some (old) Radio Shack pagers operate on
this frequency. Also shared with remote control devices.
Channels 35 to 40 - SSB channels
 
 

On January 1, 1977, the FCC expanded the Citizen Band
from 23 to 40 channels.

Maximum RF Output Power - 4 watts Amplitude Modulation
- 12 watts peak envelope power
Single Side Band
 

The upper channels of the regular 40 are often used by SSB
CB'ers but all modes (AM & SSB) are permitted on any frequency.
You'll hear something that sounds like 'Donald-Duck' if a
channel is in use by a strong SSB source. If your radio is
equipped with side-bands switch to upper or lower and adjust the
clarifier knob until you find the best-sounding place. Side-band
talking allows further range and more power but is slightly
different then regular CB'ing.
All modes (AM & SSB) are permitted on any frequency.
In England, CB's use the same channels and frequencies,
except that they use FM instead of AM.

Checking a CB Mobile Antenna

Back to the table of contents
1. Disconnect the coaxial cable from the transceiver.
2. Connect an ohmmeter to the outside of the cable connector
at the transceiver end and to a ground on the vehicle.
The ohmmeter should indicate pretty much zero. If not
check the antenna mount.
3. Connect an ohmmeter to the center pin of the cable at the
transceiver end and to the vehicle ground. The ohmmeter
should indicate an open circuit (infinite resistance).
If not, the antenna may have a shunt-type matching
transformer.
4. Connect the ohmmeter as in Step 3 and connect a clip lead
from the antenna whip to a ground on the car. The
ohmmeter should indicate essentially zero resistance. If
not, the antenna may use capacitive coupling.
5. Check SWR's.
6. Use a field strength meter as you walk in a circle around
the vehicle with the mike keyed.

The impedance of a microphone may be between 30 ohms and
several megohms. Typically the source (mike) impedance is
300-500 ohms. A replacement mike may be lower then what was
originally on the C.B., but not higher.

CTCSS or PL Tones

Back to the table of contents
Continuous Tone Coded Sound Squelch (CTCSS) is sometimes also
called PL (Private Line, which a Motorola Trademark). PL can be
analog (just PL) or Digital PL (DPL). Some other terms used by
various companies are Private Call, Tone Squelch, Channel Guard,
etc.
Analog PL is a low level tone (60 through 300 Hz) which is
transmitted along with the radio signal. Usually the tone isn't
audible to humans, but some people are able to hear the higher
ones.
DPL uses a digital word instead of an analog signal, and a
turn-off code.
The purpose of PL is to unsquelch the a radio only when the
proper tone is sent with the transmission. This locks out
unwanted signals including interference and transmissions made by
users sharing a frequency. It can be used to activate certain
repeater sites, exclude distant users, or identify users.
Some scanners allow you to exclude conversations which do not
have the correct code as well as many transceivers. Other scanner
uses might include identification of distant stations during skip
season.
Scanners which have PL capability require a specific board.

frequencies).

Digipeaters

Back to the table of contents
A DIGItal rePEATER (a digipeater), is basically the same as a
regular repeater - it listens and then repeats a transmission,
but on the same frequency. Digipeaters are used to extend the
range of digital transmissions just like voice repeaters extend
the range of voice transmissions. MDT's may use these as well as
many other digital communications, including amateur radio.
Since these operate in a simplex mode it's hard to tell if you
are hearing the repeated station or the original.
 

DTMF Tones

Back to the table of contents
The DTMF tones are what you'll hear when you use a touch-tone
telephone. You'll also hear it on the airwaves. These tones are
made up of two frequencies which are listed below. There are a
couple program for the IBM compatible series of computer which
will translate tones to their corresponding numbers.

1 - 1209 & 697 7 - 1209 & 852
2 - 1336 & 697 8 - 1336 & 852
3 - 1477 & 697 9 - 1477 & 852
4 - 1209 & 770 * - 1209 & 941

The Emergency Broadcast System (EBS) tones that you may hear
on TV or commercial radio stations consists of a 853 Hz tone and
a 960 Hz tone for a duration of at least 22.5 seconds.
 

Family Radio Service

Back to the table of contents
Family Radio Service, or FRS, is a Citizens Band-type service
which operates in the 460 MHz band. This new service allows
users unlicensed very short distance communications using
handheld two-way radios with 1/2 watt output. These radios MUST
have only "rubber-ducky" antennas and no external antennas or
amplifiers are permitted. The radios will operate on 14
frequencies around the GMRS service in 462 MHz.
To minimize interference with GMRS stations very little
deviation will be allowed (2.5 KHz, half the usual narrow-band FM
of 5 KHz) and a very tight frequency stability (not more then 500
Hz drift, typical ham radios on UHF can be 1000 Hz off
frequency) will be used.
Autopatch or other telephone connections are illegal but
subaudible tones and other selective calling methods are
allowed. There are no restrictions on the content of the FRS
communications.

Subj: Syr. Ang 174-Tfw Conf: (24) Scanner Ra
-----------------------------------------------------------------
I'm an Air Force Forward Air Controller (FAC) stationed at Ft
Drum and I think I can help you guys out. Just for reference
at Fort Drum there are actually 2 ranges. Range 35 which is a
scorable air to ground range run by the Air National Guard (ANG)
and the main impact area that's used for live ordnance. Those
missions are controlled by Active Duty Air Force FACs assigned
to the 10th Mountain Division. The ANG also operates the Forward
Operating Location (FOL) at Drum. The FOL is used to quick turn
A10s (The runway at Drum can't take an F16 those are turned at
Griffiss AFB). The Range is about the only one on the East
Coast that can be easily used for live air to ground missions.
We have fighters as far away as Georgia coming to the Range
to drop. On any given mission as many as 3 radios are being used
at once by fighters. They are in contact with the GCA at Drum,
the FAC or Range Controllers and one radio to talk to each other
(fighters fly as a minimum of a two ship). We also do work with
C-130 outfits to do air drops and assault landings at Drum.
Callsigns that are used are peacetime assigned and don't
change. Armed with that figuring out what's going on is pretty
easy. Range 35 always uses "RANGE 35". 174 F-16s always use
"COBRA" followed by a 2 digit number. The 103 & 104 Fighter
Squadrons (A-10) use a myriad of callsigns some examples are
"SHARK, HOG, DEMON, SAINT, FREIGHT, PIG PEN, etc". Out of
towners are usually unknown until they show up at the range. But
the callsigns are pretty much the same. The Forward Air
Controllers use "COMMENTARY, ALPINE, GRIFFIN & ICEMAN".
 

Garage Door Openers

Back to the table of contents
Why would you want to listen to garage door openers and what
would you do with this info?! Well, I don't know but a couple
people have asked me about it so here goes...
These are probably pulsed so you may not have much luck with
a frequency counter or maybe even search mode on a scanner. But
a spectrum analyzer should show it to you well.
If you do get a lock on it with your scanner you should be
able to hear the security code tones.
 

GMRS

Back to the table of contents
The General Mobile Radio Service is a personal radio band.
The frequencies are located in the UHF range and some other radio
services are mixed in the same range of 460 - 470 MHz. The
31-31.3 Ghz microwave band has also been opened up for GMRS.
This allocation can use any mode where the UHF can use only FM.
To use this service you must get a license (which requires no
exam) which covers all members of the licensee's household. The
fee is $35 for five years. Only individuals can get a license;
no businesses, though some will still have them from before 1989.
GMRS can only be used mobile-to-mobile or base-to-mobile but
no base-to-base communications are allowed. Repeaters can be
used, extending the normal range of the 5-watt transmitters.

Listening to Fire and Ambulance in Jefferson County

Back to the table of contents
    If you  live  in  Jefferson  County  and listen  to  fire and
ambulance traffic  a lot you  may wonder  what all  those numbers
mean.  Say, for example, that you heard '21-91 out at 14:23'.
    The first number,  the 21 in this case,  means the village or
town the unit is from.  Look at the list below - you'll see 21 is
Felts Mills.
    The next set of numbers are broken up.  The next number, 9 in
the example,  stands for  the vehicle  type,  look below.   The 9
stands for an ambulance.  The next number, the 1 here, stands for
the vehicle number from that area.
    If the  town or  village had  another  ambulance it  would be
'21-92'  which would stand  for the  second ambulance  from Felts
Mills.
    Other counties  may use  other methods.   The missing numbers
below are for future expansion.  The next numbers, after the 'out
at' is just  the military-style time the unit  was out of service
at.   If the number is over 12,  just subtract 12 from the hours,
in this case the time was 2:43 PM.
    You may want  to buy a map of  Jefferson  County  and tack or
tape on the number corresponding  to each village or town's fire/
ambulance department.  If you don't have room for a large map you
can use a small one or  even a home-made one.   Also, it helps to
keep a list  of the numbers  followed by the  villages and  towns
 (like below) nearby for
quick reference.
    If you hear the dispatcher  or a unit say there is a '10-10',
then this  means  there  is  a full,  confirmed  fire  under way.
This can also be called a 'working fire'.   '10-9' means there is
no fire or that it is out.
    About the 453.8125 frequency that you hear 46.180 repeated on
sometimes;  according  to a  local fireman  -  "Jefferson  County
inherited the equipment that was the "Orange Phone"  EMS Resource
system.  This equipment has now been used to set up the two tower
system now used for fire communications.  You could probably hear
traffic on some other nearby freqs,  although they don't see much
use..."

Marine

Back to the table of contents
Vessels not required to carry a marine radio are recreational
vessels less in 20 meters in length. But if these vessels carry
a radio they must maintain a watch on channel 16 whenever the
radio is operating and not being used to communicate. They may
alternately maintain a watch on channel 9, the boater calling
channel.
Vessels which are required to carry a marine radio, such as
commercial fishing vessels, must maintain a watch on channel 16
when the radio is not being used for communication.
All U.S. government and military vessels and shore stations
having a marine radio shall maintain a watch on channel 16 while
underway, whenever practicable. Government ships in portions of
the St. Lawrence Seaway or Coast Guard operated VTS may terminate
listening on channel 16 when directed by the Seaway or VTS to
call and work on a designated shop movement frequency.
Every power-driven vessel of 20 meters or greater, every
vessel of 100 tons and upward carrying one or more passengers for
hire, every towing vessel of 26 feet or greater, and every dredge
and floating plant near a channel or fairway must maintain a
watch on both channels 13 and channels 16 while it is underway.
Persons meeting this requirement must be able to speak English.
There rules apply to all foreign vessels operating within the
U.S. territorial waters, the Great lakes and their connecting and
tributary waters.
All ships, including foreign ships, are required to carry
radios capable of tuning to channels 5A (required only in Puget
Sound) and channel 22A.

Note that the letter "A" indicates simplex use of an
international duplex channel, and that operations are different
than international operations on that channel. Some VHF
transceivers are equipped with an "International - U.S." switch
for that purpose. "A" channels are generally only used in the
United States, and use is normally not recognized or allowed
outside the U.S.
Boaters should normally use channels listed as Non-
Commercial. Channel 16 is used for calling other stations or for
distress alerting. Channel 13 should be used to contact a ship
when there is danger of collision. All ships of length 20 meter
or greater are required to guard VHF channel 13, in addition to
VHF channel 16, when operating within U.S. territorial waters.
Users may be fined by the FCC for improper use of these channels.

The above was gotten from the US Coast Guard Homepage -

Miscellaneous Scanner Info

Back to the table of contents
Sometimes one frequency may be used by various agencies. For
example - some schools may use the same frequency.
After programming your scanner always check to make sure that
you do not have duplicates - it's a waste of channels and slows
down your scanning. Some scanners check for duplicates when you
type a new frequency in.
When searching for new frequencies with your scanner search
in small segments - the more often you scan a frequency the more
likely you are to find something, especially short messages.
Remember when using your search mode that your scanner might not
necessarily stop on a valid frequency. Know your scanner's
birdies and quirks and watch for interference.
You can also buy or make antennas made for specific frequency
ranges, which will give you better performance if you're scanning
a certain range a lot. They make them for the 800 MHz range, 46
MHz range, and many others.
Oh, and don't forget to try hooking your scanner up to the
output of your satellite dish (just make sure there isn't a big
pre-amp in between!).
 

Mobile Data Terminals

Back to the table of contents
A Mobile Data Terminal is a device that looks kind of like a
little computer mounted in the cop car (you won't see them around
here for awhile, probably). It usually has a small keyboard and
CRT and is used to give the officers data right on the screen in
the squad car.
The digital transmissions are usually in the 800 MHz range.
The transmission standards and protocols will be complex and
probably pretty well guarded. Apparently some police forces are
having a hell of a time getting these things to work right as
well as getting any benefits out of them, including the New York
State Thruway Authority who have had them for years.
Also, there has been some trouble from some police unions
because some of these devices include patrol car tracking devices
built into them.
What would you need to eavesdrop on these? You would need a
matching MDT set up with the same protocols, etc. Not an easy or
cheap thing to get, not to mention finding someone to program it
for you AFTER you got the proper codes!
An easier method might be to use a Tempest Interceptor or
equivalent. See info on this device below.
 

NOAA

Back to the table of contents
NOAA weather radio provides continuous broadcasts of the
latest weather information directly from National Weather offices
which is a service of the National Oceanic and Atmospheric
Administration of the U.S. Department of Commerce.
The broadcasts are taped weather messages repeated every four
to six minutes. These broadcasts are routinely revised every one
to three hours, or more frequently if needed. Most of the
stations operate 24 hours a day and can be heard around 40 miles
away (more if you use a good external antenna). More then 90
percent of the United States is within listening range of a NOAA
broadcast.
The weather information is specific to the region within the
receiving area. Locally, marine forecasts are also routinely
broadcast. A new NOAA feature in some areas is Selected Area
Message Encoding (SAME) or Weather Radio Selected Area Message
Encoding (WRSAME). With the proper radio (hard to find right
now) you can hear only watches and warnings for your county
instead of the all the counties and areas that are broadcast.
During severe weather or emergency weather conditions regular
weather broadcasts are interrupted with special weather
statements. During this time a special tone is broadcast
(1000 Hz) to warn weather alert receivers (like what you can buy
at Radio Shack). These receivers alert the listener to turn the
receiver up or the tone may automatically turn the receiver on
(depending on the unit).
Under a January 1975 White House policy statement, NOAA
weather radio was designated the sole government-operated radio
system to provide direct warnings into homes for both natural
disasters and nuclear attack. This capability is to supplement
warnings by sirens and by commercial radio and TV.
Normal AM/FM radios do not usually have the NOAA weather
frequencies but there are a few that do, as well as some CB's,
many scanners (if yours doesn't just program in your local
frequency and use the lock-out until you want to listen to it),
and some shortwaves as well as specialized weather-only radios
(mentioned above).
A warning; whether it is a severe, tornado, etc, means that
the weather pattern has been sighted in the area designated in
the warning. A watch means that the particular area under the
watch has the proper conditions for the weather pattern to occur.
 

NORAD

Back to the table of contents
NORAD's Air Intercept Control Channel is 364.2. This is the
primary & busiest of NORAD's UHF voice frequencies, and it's used
in all NORAD Regions. Very often, contact will be established on
364.2 MHz, and then switched to another frequency used within the
Regional Control Center's area.
 

Police & Customs

Back to the table of contents
    If you're looking for tactical, 'secret', or 'special' police
frequencies don't expect that  they'll always be listed in an FCC
database of licenses under the 'POLICE' designator, of course.
    Try looking under the  local government  freqs.   They may be
using these (illegally)  or even the  input frqeuency  of a local
gov't repeater.   Maybe even  another frequency  not listed under
ANY license for your area.

    The below codes are the  10-codes suggested by the Associated
Public Safety Communications Officers (APCO).  Your area may have
more then these or some of the below codes may be different.  The
best way to find out is just to listen.
    A 10-code with a '/' before it means it is an unofficial APCO
code used by some police.   A '*' means that I've heard this code
is used in this area.   Locally the police don't  seem to use the
'10' in the code very often.   For example,  an officer might ask
for a 28,  not a 10-28,  for Vehicle  Information.   But the code
11-92 seems to be used in full.

  Other agencies which  use the  State Police  radio  service are
designated as 7D units with two digits if they are a state agency
such as  park police.   The park  police  also use  the Sheriff's
department but use their 7D-## call numbers when doing so:
   7D-10, 7D-15, 7D-16, 7D-17, 7D-18, 7D-19, 7D-20, 7D-21 (boat?), 7D-50
 
   Villages that use the radio service are designated  as 7D-3#
units: (Some villages use both)
    Carthage - 7D-310, 7D-311, 7D-312
    Adams - 7D-301
    West Carthage - 7D-345, 7D-346
    Clayton - 7D-305
    Lowville - 7D-330, 7D-331
    Pulaski - 7D-340
    Sackets Harbor - 7D-380
 
    US Border Patrol unit 451 - 7D-511
 
  The portable radios used by the  state are designated as 6D-3##
units and do not have much range.  Base portables such as the one
at Alex Bay carry quite well.
  The DEC  also uses the  state  police from  time to time.   The
units are  designated as  7N-6## units as  Jefferson County is in
Region 6 of the DEC.    The last three numbers also appear on the
license  plate  of  the  vehicles.   They  also  have  their  own
frequency but  it is  used statewide  with repeaters.   It offers
little information to listeners.

                               Customs
                               -------
   There is a repeater for customs in Ogdensburg and one for Alex
Bay  (the repeater itself is in Watertown).   'Sector' is acually
the base in  Florida,  Alpha  units are  Agents/Law  Enforcement,
Charlie units are communications specialists, Delta units are the
Contraband Enforcement Team,  India units are Inspectors.   Every
once in a while you may hear Lima units, which are aircraft.

Remote Control

Back to the table of contents
The frequencies listed under the Remote Control section are
used for remote control (R/C) models, and are sometimes called
'in-between channels' or Alpha channels on the CB band (some
illegal CB's are modified to transmit and receive on these bands).
49, 50, 52, 53, 72, 75 MHz frequencies are also being used
for remote control models.
Try scanning the frequencies used by these when you're near
someone using one. When you lock onto one you should be able to
hear the change in the sound when they move the various controls.
 

SAM (Special Air Mission) Codenames

Back to the table of contents
SAM - Special Air Mission
SAM callsigns belong to the 89th Military Airlift Wing (MAW)
and they are responsible for 'moving anybody who is anybody'.
When a callsign such as SAM 26000 is called it is the tail
number of the aircraft regardless of who is on board.
Air Force 1 and Air Force 2 are exceptions. If the president
flies on a Marine, Navy, or Army aircraft the callsign is the
branch of the service and a '01'. Example - Marine One, Navy One,
Army One.
(Thanks to Bill Staab for this info, which I've taken almost
verbatim from his text.)
 

Scanner Law

Back to the table of contents
Section 397 of the NYS Vehicle and Traffic Law - titled
"Equipping Motor Vehicles with radio receiving sets capable of
receiving signals on the frequencies allocated for police use".
At the end of this section of law there is a section called
"Notes of Decision" - "#5- Seized equipment" clearly states: "In
the absence of specific statutory authority, a radio seized by
the police in connection with an arrest and conviction for a
violation of section 397 of the vehicle and traffic law is not
considered contraband and may not be retained, destroyed or
rendered incapable of receiving."

Of course, the law starts out by saying that if you're not a
police officer, OR a peace officer, you CAN'T have the scanner in
your vehicle.

The above was sent to me by Mike (WatnNY@aol.com).
 

Scanner Transmitting

Back to the table of contents
What, you say!? My scanner is a receiver only! Well, any
piece of equipment that uses crystal controlled or ceramically
resonated circuits generates a spurious output. So that means
that when your scanner is on and receiving it's also transmitting
a small but distinct signal (also see Tempest) and theoretically
someone could even tell what frequencies you're listening to.
This also holds true for transmitting and transceiving
equipment - though the equipment couldn't be transmitting at the
time that this spurious signal was being picked up.
Also, with the right equipment and knowledge a person could
tell the exact model of a radio and even tell two radios apart.
Have I made you paranoid now? Well, this information is
mostly to make you aware of this - it's not like the FCC drives
around the country and checks to see if people are listening to
cellular telephone conversations, right? But it is used by
various governments and agencies around the world.
But you could use this method to try and pick up some of
those freqs you just can't find elsewhere. You do have to find
some specific information, but sometimes finding this information
is more trouble then its worth. You might find that investing in
a frequency counter might be easier! The nice thing about this
method is the radio you're trying to monitor doesn't have to be
transmitting (and this method won't even work when it is).
First you have to know the approximate range that the radio
you want to monitor is going to be using. Otherwise you'll be
doing a lot of scanning and since you have to be fairly close it
might be a bit awkward.
Then you have to know what kind of radio they're using and
the first I.F. (Intermediate Frequency) Now, if you can
recognize the type of radio from a distance, great. But if you
have to get close enough to check it out you might even be able
to see the display or a label showing the transmitting frequency,
which would save you going through the following methods.
Anyway, you must have the technical info on the radio which
shows the first I.F. Take the I.F. frequency and subtract that
frequency from the range that you know the radio must operate on.
Now scan that frequency range while getting as close to the radio
as possible. If you have a good scanner and good antenna it will
stop on a weak but constant low tone. Now take the frequency and
add the I.F. frequency back to it. You'll now have the frequency
that that radio is receiving and transmitting on (unless it
transmits on one and receives on another).
Say the radio you want to find the transmit freq for is an
amateur radio on the 420-450 MHz range. You know the I.F. freq
is 24 Mhz. Subtract that from the 420-450 which gives you
396-426. Scan this range and get as close as possible to the
radio. When you hear a weak and constant low tone add the 24
back to it. Say it stopped on 424.537. Add the 24 and you'll
get 424.537, the frequency the amateur radio is set to transmit
at!
You MIGHT be able to take some guesses on some of the above
parameters but this isn't a simple method in the first place and
there's a lot of variables involved.
But if you can't find a freq any other way this method might
work for you. Try it with your scanner on a friend's radio if
you can to see how well your scanner does it.
 

Subs

Back to the table of contents
Well, you're probably not going to worry about too many
submarines around here so this is more of general interest. The
purpose of a sub is secrecy & stealth so even if you lived in a
place like Groton, Connecticut ("The Sub Capital of the World"
as someone who lives there put it) you probably won't hear them.
Much of this message was taken from a message posted by Bill Funk
on the FidoNet scanner echo and confirmed by a number of
different people there and a couple places elsewhere (and it'll
sound familiar if you read any of the newer sub novels and watch
movies like "Crimson Tide" etc. Pretty realistic!)
Most of their transmissions utilize a compressed data stream
to a satellite using a narrow beam. This way the signal can't
easily be intercepted or detected and the sub's position won't be
given away. The antenna used for this looks like another
periscope and is used for both transmitting and receiving,
although they can transmit on almost any frequency they don't
usually do this (for obvious reasons).
When the sub is submerged VLF & ULF signals are used, though
the information rate for these transmissions are on the order of
one character every 20 seconds or so. A trailing antenna that's
hundreds of feet long is used for receiving these signals.
Usually these transmissions are only used to tell the sub
that there is a transmission to receive. The sub then goes to
periscope depth, receives the satellite transmitted data as per
above and then dives again.
A couple people mentioned that you might be able to hear the
subs on regular marine channels when they are towed into port
by tugboat.
 

Television

Back to the table of contents
Frequencies in the 470-512 MHz range (Ch 14-20) may be
assigned to Public Service mobile use in major metro areas. No
transmitters are allowed on 608-614 MHz (Ch 37). Each TV channel
is 6 MHz wide. The video carrier is 1.25 MHz above the start of
the range. The audio carrier is 0.25 MHz below the end of the
range. Television audio is wideband FM. Some TV stations may be
offset +/- 10 kHz.
 

Tempest Receiver

Back to the table of contents
A Tempest Receiver or Van-Eck Receiver, is a device for
intercepting, from a distance, a signal from a CRT display's NTSC
video signal (I assume they make them for different video signal
protocols for use in other countries).
That means anyone with this device can sit outside your
house, business, or wherever; a short distance away anyway, and
see what is displayed on your TV set, your computer's monitor, or
any other form of CRT (scary, huh?).
It could probably also be used to see what is displayed on a
MDT (you'd have to follow the cop around or whatever), maybe a
laptop? I'd like to hear from someone with more knowledge on
this.
 

Trunking

Back to the table of contents
Trunking is easy to figure out but not always easy to listen
to. See above for the frequency range normally used by trunked
systems.
A trunked system USUALLY consists of at least five channels,
in multiples of five most of the time. One channel is used as
the control or handshake channel. It is usually changed once a
day or sometimes twice. It's audio consists of a continuous
"buzzing" sound.
Each day monitor all of the repeater frequencies and lock
out the new control channel and unlock the control channel from
the day before. Eventually you may find a pattern for quicker
listening.
There may be more then one control frequency, meaning that
there are probably sub-systems operating; making your listening a
bit harder.
Also, there may be frequencies never seeming to be used by
anything. These may be special purpose channels and are probably
worth keeping in your scanner if you have enough room, just in
case.
If you find out that the system that you are monitoring is a
Motorola, try loading the frequencies into the scanner in
descending order. There is an unsubstantiated theory that the
trunking system's computer assigns a new frequency in descending
order every time a mic is keyed. Some people have reported some
success with this method.
If you have enough bank room you can load in the frequencies
for the mobile units in a trunked system. Just subtract 45 MHz
off the base frequencies. If you are close enough you'll be able
to pick up the mobile units without having to listen to the rest
of the trunked system, but you must be pretty close.
There are a number of different kinds of trunking systems...

Motorola Systems
----------------
Can be 1 to 4 control channel frequencies.

Type I. This system is the oldest and uses a combination of
around 14 combinations of a variable length fleet/subfleet/ID.

Type II. This is a newer version which uses talkgroups
instead of the fleet/subfleets of Type I. This system have be 3,
7, or 15 subfleets, plus one fleetwide channel in each fleet but
there can be quite a few talkgroups assigned to a system.

Type III. A combination of Type I and II.

EF Johnson LTR Systems
----------------------
Completely different from Motorola. There are no dedicated
control channel but uses a home channel. User group(s) are given
a specific home channel to use. For example, if channel 1 is
being used by user 1, who's assigned to that channel, another
user who tries to transmit while the first user is talking would
be handed off to another channel.
 

USAF Air Operations

Back to the table of contents
The USAF uses several nets and over the past few years they
have changed and combined. There is a system called Global
Command and Control System (GCCS) in place for keeping track of
all airlift and tanker operations worldwide. The system is
composed of HF stations located all over the world. Some are
part of the Mystic Star Network (Presidential Support) and some
are part of the now defunct Strategic Air Command while others
are run by remote control from stations hundreds of miles away.
For example, the Loring Maine station is remote controlled by
Macdill AFB in Florida which use HF radios referred to as PACER
BOUNCE. They are manufactured by Harris Communications of
Rochester NY and are state of the art with digital tuning, VOX
controlled phone patches, computer interfaces, etc. and use the
best antenna system for an outstanding, reliable system.
The system uses all the same basic frequencies but the call
signs vary. MAINSAIL is the generic call sign for any of these
stations, HILDA belongs to Air Mobility Commands (formerly
Military Airlift Command) Operations Center at Scott AFB IL.
Most of the other call signs such as Andrews, MacDill,
Loring, etc refer to that particular station.
Calls for SKY KING are for the old SAC alerting system. The
messages are nothing more then encoded message traffic. A lot of
what you would hear are weather updates, ETA updates, etc and the
system is only occasionally used by ground stations. The best
time to listen for that is when an operation is going on.
(Thanks to Bill Staab for this info, which I've taken almost
verbatim from his text.)

What's Active on Shortwave

Back to the table of contents
The 120-41 meter bands are usually most active after dark and
31-11 meters are active during daylight hours. Frequencies in
the list will and do change, somtimes without notice.
 

Wireless Mikes/Bugs/Bumper Beepers/Walkie Talkies

Back to the table of contents
The wireless mike frequencies listed in the frequency
allocations above and in the list are used by fast food drive-
thru's, wireless mikes, bugs (government and otherwise), newer
walkie-talkies, local preachers at churches, entertainers while
on stage, husbands checking up on their wives and vice versa,
companies checking up on their competitors; the list is endless.
Many of these are fairly low power so you would have to be
quite close to pick them up.
Frequencies with descriptions may be shared with others.
Ex. - A fast food frequency may also be used by wireless
mikes in a church elsewhere.
Some common search ranges 49 - 50 MHz, 72 - 76 MHz, 88 - 108
MHz, 174 - 216 MHz. Federal Agencies seem to stick within their
band when using bugs = 162 - 174 MHz, 406 - 420 MHz, Federal Body
Mikes 169.2 - 173.4 MHz.
Bumper Beepers are used for the tracking purposes of a car
'vehicle' to keep up with the actions of an individual. They can
also be used on the person of an agent or individual to keep
track of his position.
According to James M. Atkinson - "Most recently purchased gvt
microwave surveillance gear seems to be running between 900mhz to
5ghz, with a few systems operating on the 7/8 Ghz bands.
"Also, keep in mind that the pros love to use ultra low power
devices which use the power lines as the transmission medium/
antenna (9khz to 300 MHz). Devices typically operate below 10mw,
often below 1mw. The devices typically use Wide FM and use voice
inversion encryption... VERY easy to demodulate.
Note: According to a recently obtained DOJ surveillance training
manual:
"The typical range for the 28 Ghz devices is six miles, the
typical range of the 2.4 Ghz is thirty miles, and the typical
range for the 1.7ghz is 44 miles.
"... frequency modulated applications should operate below 3 Ghz
to take advantage of the favorable frequency propagation
characteristics of that part of the spectrum.
"...Frequency Hopping and Direct Sequence Devices speed spectrum
devices should operate above 1.5 Ghz, this will prevent the
emissions from being detected by electronic countermeasures."

DOT Transceiver Freqs

Back to the table of contents
No, not the radios those guys with the yellow trucks and
snowplows use.
"Dot" stickers are used by the manufacturer or distributor to
indicate the frequency of otherwise identical transceivers. They
are often found in rental inventories and on construction sites.

Types of Bugs

Back to the table of contents
Telephone - Attached to a phone, either serial or parallel.
Picks up phone conversations or some can be
remotely activated to pick up conversations in a
room (the latter does not pick up phone
conversations).
VOX - Transmits the audio only when a sound is made.
Usually can still be picked up by professional bug
hunters by putting out a tone to hold the VOX circuit
open.
Remote Activation - Has a small receiver and can be turned
on on command. Can be picked up with
a NLQ (Non-Linear Junction Detector)
but otherwise hard to pick up when not
on.
Burst Transmission - Stores a few seconds of speech and then
transmits it in a compressed burst.
Hard to detect.
Encrypted - Just what the name says.
Spread Spectrum - Very, very hard to detect but a good
spectrum analyzer should be able to find
it.

Drive Thru's

Back to the table of contents
Sometimes you can find some interesting listening on drive-
thru freqs. Sure, there's a lot of "I'll take two Big Mac's and
small fries" but once in a while you'll catch an employee
insulting a drive-thru customer or interesting chit-chat.
Drive-thru transmitters are very low power so you have to be
fairly close to pick them up, depending on conditions and your
equipment. Usually about half a mile is the range.
Some drive-thru's use simplex systems which means they
transmit on one freq and receiver on another but a lot of the
time you can find the one freq which has both sides of the
conversation. Or sometimes there is a frequency for employees
and one for the drive-thru (like the Burger King on Arsenal
Street in Watertown).
For the drive-thru freq you may hear outside noise until
someone orders, a dead carrier, or nothing at all until a vehicle
trips a detector. You then may hear a tone and then the regular
ordering sequence.
See the frequency manual for drive-thru freqs around here and
if you're searching elsewhere most every possible one is listed.
But a lot of times its best to use the search function on your
scanner rather then poking each of those in - just check through
them to find the likely ranges.
Some drive-thru's do not use transmitters so don't waste your
whole lunch break if you can't find after a reasonable amount of
time - it may be a wired system.

I'd like to thank the following people, business', BBS'
organizations, BBS' and magazines/books. They've been great
sources of info, frequency lists (sometimes that one frequency
I've been looking for forever), and/or just nice to do business
with and talk about my hobby with. Some of the text in this file
has been taken verboten or nearly so from some of these people's
files.

Freqs, Info, Corrections

Back to the table of contents
If you have any frequencies, info, or corrections to
contribute please write me at my registered listening station
(KNY2ADC) address below.
If you think you can write up any part of this text better
then I, please feel free to and drop it to me for perusal. I'm
no expert on this and if anyone has more knowledge on a
particular area I'd gladly incorporate it into this text,
crediting you fully of course.
 

Getting the Above to Me

Back to the table of contents
I'm open to any mode of reception of any new frequencies
including transfer of files over the modem (the fastest and
easiest way to incorporate info into my files), fax, voice-
communication, or even plain ol' paper. Or if you contact me on
one of the local BBSes, nets, or the Internet - you can attach
a file or include text in the message to me, which works just as
well...
 

Becoming a Registered Listening Station

Back to the table of contents
Also, if you are interested in becoming a registered monitor
station from CRB HQ please write me for more info. These ID's
supersede earlier registry projects such as WDX, WPE, etc and are
similar to callsigns. The ID's can be used on communications
correspondence, signal reports, QSL's, etc and 1000's of HF/VHF
/UHF monitors are registered all over.
 

Radio Mods & TextFiles

Back to the table of contents
I do have a number of modifications for scanners and some
shortwaves and amateur radios. Most of them can be done by a
fairly handy person with a little experience. But some are a bit
more complicated so I wouldn't recommend them if you don't have
complete confidence in your electronics abilities.
I also have available the textfiles on how to convert an old
AM table model radio, clock radio, transistor radio, or car
radio/stereo into a multi-band shortwave receiver. And many,
many other textfiles on electronics and radios including a
listing of all cellular telephone frequencies and channels (these
are for educational purposes only!).
Contact me for more info or if you have any mods for scanners
or interesting textfiles yourself.
 

Closing Notes

Back to the table of contents
Just one more note - we are continually being threatened with
more and more restrictions to this hobby. Keep an eye out for
new laws and signs of new laws to come, many times needlessly
regulating the airwaves and how we interact with them. Let those
who make these laws know what you think.
Also, a great medium for the exchange of free information is
being threatened - the Internet. Don't let it happen.
Write to your congressperson and let him or her know just
what you think...
According to a law passed late in 1994 it is now illegal to
listen to cordless phones, as well as cellular.

That's all for now, until the next version, so enjoy and keep
scanning!
