Low TX Audio


John B. (AD5RN)
 

After an RF feedback event, my IC7000 has very low TX audio. The TX power meter barely moves when speaking into the microphone in SSB mode, and on FM, the deviation is only 1 kHz. The MIC Gain setting in the menu is at maximum. However, in FM, if I enable PL tone, its deviation is correct (~0.7 kHz). I have tried three microphones---no change. Audio fed into the back of the radio for digital modes is also low, requiring me to maximize the AF drive from the PC to get 40W out of the radio in FT8.

I tried replacing IC452, but that did not fix it, and I still have the same problem.

Has anyone seen this before, or are there any suggestions?

Thank you,
John, AD5RN
