Cobra 25 GTL/LTD/CLASSIC
SAMS PHOTOS: 207
AM LIMITER: D-9
POWER TWEAKS:
1. Change R76 (3.3k) to a 1k (located near mike socket)
2. Change R43 (10 Ohm) to a 2.7 Ohm.
3. Change R108 (1 Ohm) to a .47 Ohm.
4. Replace stock final with a 2SC1969 transistor.
5. Re-tune coils L10,L9,L8 for maximum forward power.
MODULATOR
PARTS NEEDED: 1- 220uF (16 to 25 volt) electrolytic capacitor.
1- 100 to 200 Ohm resistor. (1/4 to 1/2 watt)

ASSEMBLY:
1. Make sure your radio is peaked out.
2. Unsolder JP6 near final.
3. In JP6 holes, solder the 220uF capacitor. (negative side of cap. faces final)
4. On the solder side of the board, solder the resistor across the 220uF capacitor.
You can use different resistor values to get the desired dead-key.

VARIABLE POWER:
1. Find the two wires that are attached to the RF gain control, follow them to the PC board and UNSOLDER them.
2. Solder in a jumper wire from where you removed the wires on the board. This will restore receive.
3. Place the two wires from the RF gain control in your mod kit by soldering one wire to each of the 220uF capacitors leads.

REPAIR TIPS:
25 GTL:
1. Channel display reads all 7's or 8's: Leaky/shorted C104(470uF 10v). Replace with a 16v or 25v.
2. NO TX: Check for shorted 33uF(10v) capacitor across C87.
3. OVERMOD: Check D19,TR14,VR5
25 LTD
1. OVERMOD: Check D9
2. LED goes out and NO TX when keyed up: Check C118
25 LTD Classic:
1. Burned R89(15 Ohm 1/2 watt): Replace with a 1 watt.
2. OVERMOD: Check for missing or cut D9, missaligned VR5.

Cobra 29 GTL/LTD/CLASSIC
POWER TWEAK #1:
1. Change R58(10 Ohm) to a 2.7 Ohm.
2. Change R123(1 ohm) to a .47 Ohm.
3. Re-tune L14,L13,L12 for maximum forward power.
POWER TWEAK #2
1. Remove final and replace with a 2SC1969 transistor.
2. Remove R123 and replace with a jumper.
3. Replace C58 with a 180pF capacitor.
4. Re-tune coils.
CAUTION!!! I do not know if both of these power mods can be done at the same time!!!

AM LIMITER: D-11
MODULATOR AND VARIABLE POWER
ASSEMBLY:
The instructions are the same as the Cobra 25 above,EXCEPT the following:
1. Unsolder JP36 instead of JP6.

REPAIR TIPS:
29 GTL:
1. "Motorboating": Locate C242(.001)on pin 5 of TA7222 audio ic and move to pin 4 of ic.
2. Weak mic gain: Some raios have a 2SC372 mic amp. Replace with a 2SC945.
3. Receive on adjacent channel: Bad solder joint to C131 (next to 10.240 crystal).
29 LTD:
1. OVERMOD: Check D11
2. PLL dead, no TX or RX: Shorted C112
3. No TX/RX with Channel LED lit on RX and then goes out when keyed: Bad /shorted C119.
29 LTD Classic:
1. OVERMOD: Check D11. Missaligned VR4.
2. Internittent audio/modulation: Bad solder joints on pins 1&2 or 2&3 of audio ic.
3. TUNE UP TIPS: L11 is the TVI trap. DO NOT adjust!!! Stretching L12 gets moe output. L14 peak is about a turn or two up from factory original setting.

Cobra 148 GTL
POWER TWEAKS:
1. Remove TR24
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.

MODULATION: Cut R131
AM POWER: VR10

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.

2. Remove D36
3. Jumper D35
4. Follow the RED WIRE from the clarifier control to the PC board and UNSOLDER it.
5. RESOLDER this RED WIRE to pin 3 of regulator IC MB3756.
6. Follow the ORANGE WIRE from the clarifier control to the PC board and UNSOLDER it.
7. RESOLDER this ORANGE WIRE to the PC board ground.
NOTE: The Orange and Red wires may need to be reversed in some radios for this to work right.
8. Re-align center slot by adjusting CT3.
If all went well and you didn't smoke your radio, you should slide about 1 Kc up and 4 Kc down.

NEED MORE SLIDE??: Install a 5.6uH choke on the banded end (grounded end) of the varactor diode D37 or replace D37 with a super diode.

CHANNEL TWEAKS:

EASY TWEAK: Install EXPO 100 kit "B".
FOR THE DRILL HOLES ALL OVER MY RADIO LOVERS...:
1. Replace 11.1125 crystal with a 11.3258 crystal.
2. Isolate the ground pin 10 of the MB8719 PLL by cutting the PC trace.
3. At this point, turn your radio on and check to varify that all channels are locked in and working. If it is not, adjust these in the following order:
a. CT3 for USB.
b. L20 for LSB.
c. L19 for AM.
4. Install a SPST switch between pins 11 and 12 of the MB8719 PLL
5. Install a SPST switch across the cut you made to isolate pin 10.
6. Check all connections for shorts.
7. Check to make sure everything is working before you drill holes for the switches!

Frequency Expansion

1) This is one of the more difficult mods out there.
2) Open the bottom cover of the radio .
3) Find the PLL Board. Its the one with the 64 pin chip on it.
4) At the front of this board by the PLL chip ther are 2 resistors R540 and R539.
5) Cut them.
6) Close the radio up. Turn it on.
Tweak and Peak

Audio limiter - R247
AM Power - VR 111
SSB Power - VR 103
RIT Modification

1)Remove top and bottom covers.
2)On the top of the main board find D140.Cut it.
3)Solder one end of a 10 OHM resistor to the location in the picture below.
4)Take a 7.5v zener diode and solder the end without the band to the small brass shield.
5)Now solder to other end of the diode to the open end of the resistor.
6)Find the PC Board that is behind the RIT Knod

7)Cut the trace as you see in the picture above.
8)Solder a wire(See the green wire in the pics) from the point that the diode and resistor meet togeteher to the bottom of the board where you made the cut.

Aligning the RIT

1)Place the radio so that the smaller PC Board is facing up.
2)Turn it on and dial up 28.000 MHZ and put the rit dead center.
3)On the samller PC Board locate J502.(upper right)
4)Pull the grey cable off the board and connect it to your frequency counter. (Sorry you can't use them $49 dollar specials from copper. You have to have a frequency counter with a probe on it)5)Hook up the probe and if it should read 38.695 +/- 100 Hz.
6)If not then adjust L501.
7)Put the radio back together.You shound have about 6KHz of slide.

 President Grant Export Mods

President Grant extra Channels
1)The switch needed is a SPST/CENTER-OFF type.Mount this in the radio somewhere.
2)Find the PLL MB8719 chip.Find pin #11 and cut the trace going to it on the foil side of the PCB.
3)Solder a 4.7k ohm resistor across the cut that you just made.
4)Now you are ready to attach the wires from the switch to the locations on the PCB.
5)Solder a wire from the top pin on the switch to PCB ground.
6)Solder a wire from the middle pin on the switch to pin #11.
7)Solder a wire from the tbottom pin on the switch to pin #9.
(If you do not get ALL the new channels adjust the VCO coil,l-18)
With the switch in the UP position:

12 = 27.875 17 = 27.935 22 = 27.995 26 = 28.035 13 = 27.885 18 = 27.945 23 = 28.025 27 = 28.045 14 = 27.895 19 = 27.955 24 = 28.005 28 = 28.055 15 = 27.905 20 = 27.975 25 = 28.015 . 16 = 27.925 21 = 27.985 .

With the switch in the CENTER position is regular channels

With the switch in the DOWN position:

12 = 26.335 17 = 26.395 21 = 26.455 24 = 26.475 13 = 26.345 18 = 26.405 22 = 26.465 25 = 26.485 14 = 26.355 19 = 26.425 23 = 26.495 26 = 26.495 15 = 26.365 20 = 26.445 27 = 26.505 16 = 26.385 .

President Grant SLIDER mod
1) Cut D-45.
2) Find D-79 and jump it (Solder a wire across it)
3) Remove r-120 and replace it with a 470 ohm resistor.
4) Find the BLUE wire from the clarifier knob and cut it just before it connects to the PCB. Solder it into the hole that is next to where R-120 is.
5) Find the GREY wire from the clarifier knob and cut it just before it connects to the PCB. Solder it to a constant 8.5 volt supply.(This can be the center pin of TR-39 )
Hopefully this should give you about 3 khz of slide.

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" ?

"I don't recommend removing TR32 as it disables VR12 ALC, SSB power will be at full blast.
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."

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.

2. Replace C173 (180pF NPO) with a 220pF NPO ceramic capacitor.
3. Re-tune coils L32,L30,L29,L28 and VR8 for maximum forward AM power.

CLARIFIER:
1. UNSOLDER and remove D30.
2. UNSOLDER and remove D29.
3. Add a jumper in the holes from where you removed D29.
4. Cut the end of R119 that is closest to D29.
5. Add a jumper wire from R119 (the cut end) to the banded end of D44.
6. Follow the PURPLE/WHITE wire form the clarifier control to the PC board and UNSOLDER IT.
7. Resolder this wire to the PC board ground.
8. If all went well, you should slide 1 kc up and 3 kc down.

KNOWN BUGS:
The AM regulator 2SC1419 is WEAK. UNSOLDER it and toss it in the trash.
Replace it with a GE-66, ECG-152 or a NTE-152.
Relay buzzes on SSB, no am transmit, lights go dim, or the fuze pops sometimes?
Replace C179 ( a 2.2uF 25v tantalum cap located near finals) with a standard 2.2uF electrolytic capacitor.
PAY ATTENTION to the "+" and "-"!!!
