Pin 3 is the lead closest to the back of the radio. Sun, 12 Apr Connect the power wire to the 5 volt mxnual pin 3 facing the front of the radio, the far right leg of the L78MO5CV, located in the middle of the microprocessor circuit board. If you operate a lot of AM, however, this mod may not be for you. A scope is also the best way to set the ALC. Loosen the four screws on the sides of the radio that hold the PLL tray in the radio.


Although I have not tried this mod MOD 2 it is fairly straight forward. I reasoned that thebeing an ‘allmode’ radio with AM included, may use the common CB radio design practice of having a wider ‘compromise’ IF crystal filter to improve the RX audio response on AM.

I do not support or encourage any sort of illegal 11 Meter operations. Bill Nadzam was very patient in working with me on a problem that it turned out was of my own creation. The only thing that I can add is that I placed a short across diode D when I did my mod.
