Cherokee CM-10
Original version.
- Remove the bottom cover
- Directly behind the M1 button, locate the two capacitors on the front
panel that are not soldered in place.
- Using a very fine tip solder iron attach the two .1uf caps to the pads
as shown in the drawing below.
- Power up the radio and you will now see a band select function above
the M2 button.
- There are 15 bands of 40 channels each.
- A, B, C, D, E, -A, -B, -C, -D, -E, +A, +B, +C, +D, +E

Remove the bottom cover
Directly between the Audio transformer and the front mounted controller
board locate the jumper points labeled A & B..
Using a very fine tip solder iron Place a solder blob on these points.
Reset the Microprocessor by shorting the "RESET" Pads, just
right of the microprocessor.
Power up the radio and you will now see a band select function above
the M2 button.

This Pix below shows a Transceiver with the Solder jumpers at A and
B already added.
After the Jumpers are placed at A & B find the round RESET point to
the right of the
Microprocessor and short them togther. This will activate the modification.
I have had
more than one occurance that has taken a couple of resets to get the Microprocessor
to
take on the new configuration.
Power Adjustments.
AM Power= VR502 (On the circuit board it's just labeled 502)
Modulation Adjust= VR103 (Same as the above, just labeled 103)
