Wondering about the "UNCLE MOD

SUPERSTAR 1700, 3600, 3900

 

MODULATION: VR14 or cut R249
AM POWER: VR13
SSB POWER: VR12

POWER TWEAK:
1. Remove TR32
2. Replace R174 (10k) with a 1 K
3. Replace R187 (10k) with a 1 K

CLARIFIER:
1. Find the GREEN WIRE located at point 54 and UNSOLDER it.
2. Resolder this GREEN WIRE to POINT 14 (8.7 V) or to TR 41 collector.
3. Find the YELLOW WIRE on the clarifier control and UNSOLDER it. Insulate the cut end. This wire is no longer used.
4. Find D75 (located near POINT 53 and VR15) and lift one end.
5. Find R135 (33k) and lift one end.
6. Double check all work for shorts.

NO EXPLOSION? Then you should be able to track on TX and RX!

CHANNELS:
1. Locate pins #12 and #13 on IC7 (MC14008BCP chip).
2. Using a SPST toggle switch, wire as follows:
Center of toggle switch goes to pin #13
The other goes to pin #12

Your channels should work with your band selector on "D" band.

It should be able to go from 28.300 Mhz. to 28.500 Mhz. ULATOR" ?

Instead clip or remove R249. This only disables AMC not ALC.
Tune L40, L43, L44, and L33 for maximum forward swing on wattmeter.
Adjust AM power for no more than 5 watts dead-key - if running a linear amp set at 3 watts dead-key.
Adjust ALC for no more than 20 - 25 watts PEP on SSB.
For Talkback remove D80."

2. Change R126 (10k) to a 2.2k
3. Change R124 (10k) to a 4.7k
4. Re-tune L37 and L38 for maximum AM forward power.

SAMS PHOTOS: 249
MODULATION: Cut R131
AM POWER: VR10
SSB POWER: VR11

CHANNEL TWEAKS:
I have found that the easiest way to do this without hacking your radio with a lot of switches is to install the EXPO 100 kit "L" expander kit.
This is an excellent kit and installs quickly with very little tools. This way you don't have to fumble around trying to remember which switch goes where, etc...
 

CLARIFIER:
1. Cut one side of R44 and D52. Remove R174 and solder a jumper wire in its place.
2. Follow the RED WIRE from the clarifier control to where it connects to the PC board and cut it loose.
3. Solder this RED WIRE to the circuit board ground.
NOTE: Some radios have a YELLOW WIRE instead of the RED WIRE.
4. Follow the ORANGE WIRE from the clarifier control to where it connects to the PC board and UNSOLDER it.
5. Resolder this ORANGE WIRE to pin 3 of the MB3756 regulator.
With any luck, you should slide about 5Kz down and 1Kz up.

 
 
 

GRANT-XL (8719 PLL)

 

POWER TWEAKS:
1. Remove TR24
2. Replace R126 (10k) with a 2.2k.
3. Replace R124 (10k) with a 4.7k
4. Re-tune coils L37 and L38 for maximum forward swing on AM mode.

MODULATION: Remove R131
AM POWER: VR10
SSB POWER: VR11

CLARIFIER:
1. Find D52, R44 and R174 and remove them.
2. Solder a jumper from where you removed R174
3. Follow the WHITE WIRE from the clarifier control to where it attatches to the PC board and UNSOLDER it.
4. Resolder this WHITE WIRE to the PC board ground.
5. Follow the ORANGE WIRE from the clarifier control to where it attatches to the PC board and UNSOLDER it.
6. Resolder this ORANGE WIRE to pin 3 of MB3756 Regulator.

NOTE: Some radios have different colored wires on the clarifier control. They are:
YELLOW instead of ORANGE
RED instead of BLUE

If all goes well, you should slide about 4 down and 1 up.

WANT MORE SLIDE??
1. Remove D51 and put in a jumper.
2. Install a "super-diode" in place of the stock varactor D35.
3. Add a 4.7uh to 10uh choke to the banded-end of the stock varactor.

10 KC JUMP:
Basically, you need to either add voltage or ground pin #16 on the MB8719 PLL.
Here's how to do a 10 Kc UP jump only:
1. Cut trace to pin #16 on the PLL.
2. Install a 4.7K resistor across the cut you made.
3. Using a SPST switch, one side of the switch goes to the cut-side of pin #16.
4. The other side of the switch goes to pin #9 of the PLL. (8 volts)
When you apply the 8 volts, this pulls pin #16 high causing the 10 kc jump up.
Note that this will not work on all channels.

For a 10 Kc DOWN jump only:
1. Ground pin #16 using a SPST switch. No cut to the PLL is necessary.
Pulling pin 16 low will cause it to jump down 10Kc.
This too will not work on all channels.

For a 10 Kc UP and DOWN switch:
Perform the trace cut/resistor addition described above.
Use a SPDT switch and wire as follows:
1. Center of switch goes to pin #9 of PLL (8 volts)
2. One side of switch goes to the cut side of pin #16.
3. The last side goes to pin #18 of PLL (or ground)
This will allow you to jump 10Kc up or down.

77-285 MIDLAND
 
There are two printed ciruit boards for the  77-285. You must first determine which you have.
Circuit board "A"
This board can be identified because D18 has been cut.To restore full power simply resolder D18 or replace it.
Circuit board "B"
On the "B" circuit board D18 is intact (has not been cut out).To restore full power, locate D18
and trace the etch. Put a solder bridge between the open pads.
 
Channel Conversion:
STEP 1. Take the bottom portion of the case off and unplug the speaker.
STEP 2. With the bottom of the case off, turn the radio over and in this position the  Midland name should be upside down. Tilt the chasis      forward toward the face plate. As you  look at the inside panel the LC7232      IC chip
should be readable and pointing toward you (upper right corner).      You need to open
solder bridges 5 and 6 from left of the chassis(bottom left).
 
 
77-290 MIDLAND
 
STEP 1 Remove top and bottom cover.
STEP 2. Prepare an 8" small gauge jumper wire Tin both ends.
STEP 3. Remove the 1K ohm chip resistor on the radio front panel
STEP 4. At the removed resistor location, solder the  prepared jumper to the pcb pad nearest the center of the radio.
STEP 5. Solder a 1K ohm 1/8 watt lead resistor to the other end of the jumper.
STEP 6. Solder the free end of the resistor to the emitter  lead (lead nearest the rear of the radio) of Q61.
STEP 7. Turn the radio over so the bottom of the pcb is facing up and the front is closest to you.
STEP 8. Locate chip resistor R63 and remove
 
240 Channels:
Press and hold "DW" and "9" then turn radio on. Select bands by using the "19" button.
To set for 28Mhz to 29.7 Mhz press and hold "LCR" and
 "eMIC"e then  turn radio on. To switch back to 40 channel mode repeat process.
 
Microphone Gain:
1. Chip resistor R138 controls mic gain decreasing the value of the resisitor increases the gain. Generally have
270 ohm, the value can be as low as 150. If too much gain is used oscillation may occur.

Remove the bottom cover, be carful not to pull the speaker wire out. There is a black plastic rectangular plug (CN5) which is in the front center of the radio right in front of the gold colored crystal. Using small needle nose pliers, pull the plug off and
reinsert it in the next slot. You now have the 11 meter band on Band D. NOTE: You also have to pull out the calibrate knob
to get the extra channels.

Euro 3900 Power Mod

Locate the trim caps labeled "AMP", "MOD" AND "SSB". Turn these adjustment screws all the way to the right. These caps are on the same board as CN5, but on the oppisite end.  Thats all there is to it. You should see around 15 watts on AM and 25 watts on SSB

RCI 2950
 
Someone here recently posted a message asking for available mods
for the Ranger RCI-2950 10 meter radio.  Here's what I have.
 
  Frequency Modification
1. Remove the case.  I *think* you can remove either the top cover
   or the bottom cover to get to the PC board with the jumpers.
   It will be a small PC board immediately behind the front panel.
2. Locate "J2".  There will be a jumper on pins P3 and P4.
3. Remove this jumper to expand coverage to 26 MHz - 29.7 MHz.
4. Move the jumper from P3-P4 to P1-P2 to expand coverage to
   26 MHz - 32 MHz.
5. After moving (or removing) the jumper, press the CPU reset button
   (located below J2).
NOTE: Operation between 30-32MHz may require retuning the VCO.
 
  CB Channel Readout Modification
1. Locate J1.  There will be a jumper on pins P1-P2.
2. Remove jumper and place on P2-P3.
3. Press the LOCK button on the front panel.  The readout will now
   display the CB channel number 1-40 -- also will display "A" channels.
4. Press LOCK again to return to VFO mode.
NOTE:  The SHF button will not operate while in CB mode.
       This modification will disable the frequency lock function.
 
  CB Channel 9 Select Modification
1. Locate J3.  There is a jumper between P1-P2.
2. Remove the jumper and place it on P2-P3.
3. Press the "roger beep" button to go directly to CB Channel 9.
NOTE: Doing this modification makes it impossible to turn off the
      roger beep feature (unless, *possibly* you make sure the
      roger beep is turned off before moving the jumper. I'm not
      sure).
 
------------------------------------------------------------------------
  "Tuneup" Modifications
 
   Adjust VR14 (AMC) for maximum forward modification.  Mod limiter
Q32 can be removed for more modulation, but it also disables VR12
(SSB ALC) and disables variable power for SSB.  I do not recommend
removing Q32; you'll have plenty of modulation as is.
 
    Tune L34, L13, L14, L46 and L10 in AM mode for maximum forward
swing, using a peak-reading wattmeter.  Try to balance for even power
from top to bottom of frequency range.
NOTE: You'll have a LOT of trouble identifying these cans.  Sorry,
I don't know for sure where they are either.
 
    Adjust VR13 (AM High Power) for 12 watts dead key with the front
panel RF power control at maximum.  Adjust VR15 (AM Low Power) for
2 watts dead key with front panel RF power control at minimum.
>From the 12-watt dead key you should see a forward swing of 30-40 watts.
>From the 2-watt dead key you should see a forward swing of 18-20 watts.
 
    Adjust VR12 (SSB High Power ALC) for maximum PEP on SSB, then
back off just a little, with front panel RF power control at maximum.
Adjust VR16 (SSB Low Power ALC) for 5-6 watts PEP on SSB with front
panel RF power control at minimum.  You should see 40-50 watts PEP
on SSB with front panel RF power control at maximum.
