NOTEs:
75.0 MHz is Aircraft Navigation Marker Beacon.	This is near
airports on the ILS (Instrument Landing System) course.	 Three
lights are in the cockpit (Purple, Amber, White):
Purple - Outer Marker, Intercept Point, 4 to 7 Miles downrange
	 Two 400 Hz Dashes Per Second.
Amber  - Middle Marker, Cat I Decision Height, 3500 Feet
	 downrange, 1300 Hz Dot and Dashes 95 times a minute.
White  - Inner Marker, Cat II Decision Height, 3000 Feet
	 downrange, Six 3000 Hz Dots Per Seco nd.

TACAN has 126 X and 126 Y channels.  Normally only X channels
are used, unless crowded.  TACAN frequencies are tied to VOR
frequencies.  (Note: there are more TACAN frequencies than
VOR frequencies, some are blanked around the ATCRBS Beacon 
frequencies, and others are for expansion and military use).
Pulse widths are 3.5 us.  Aircraft sounds like a Top
Fuel Dragster or Funny Car when searching for lock-on.
 
There are currently five interrogation modes in use:
 
Mode 1, 2 pulses spaced 3 microseconds	 [Military]
Mode 2, 2 pulses spaced 5 microseconds	 [Military]
Mode 3/A, 2 pulses spaced 8 microseconds [Military/Civilian]
Mode 4, encrypted, IFF			 [Military]
Mode C, 2 pulses spaced 21 microseconds	 [Military/Civilian]
 
A third pulse is also included in all modes (except 4) at
2 microseconds from the first.	This is the sidelobe pulse.
if it's within @6 dB of the first pulse (or greater) the
transponder doesn't reply (as it has detected an antenna
sidelobe).  Pulse widths are .8 microseconds.
 
The reply is two framing pulses spaced 20.3 us apart,
with 13 code pulses (0000 - 7777 Octal) and an X pulse at the
center which is not used anymore).  A fourth pulse (called SPI
pulse (Special Position Identifier) is used to identify your
position when asked by a controller to "Squawk Ident", it is
4.35 us after the last framing pulse and lasts for
20 sec (about 2 scans of a long range radar). Pulse widths
are .45 microseconds.
