I don't know if I'm on to something here finally.
Checking voltages on the TX Mixer (IC9), I found a couple voltages that seem to be off.
Heres what are called for, and what is measured:
Pin.    Measured.
1 - 0.00TX.    0.00
2 - 8.23TX.    7.67
3 - 8.23TX.    7.67
4 - 0.00TX.    0.00
5 - 8.23TX.    7.68
6 - 0.00TX.    0.00
7 - 3.14TX.    3.46
8 - 2.70TX.    3.51
9 - 0.00. 0.00
10 - 0.87TX.    4.6mv
11 - 1.56TX. 4.6mv
12 - 0.87TX. 4.6mv
13 - 1.56TX. 5.1mv
14 - 0.00.    0.00

Should I be concerned with pins 10,11,12 and 13?
Thanks fellas
