[TenTec] Orion tx audio

[Byron Cordes]

Hello 
 I’m getting close to having the Orion back up . 
 One last problem, audio popping when tx. I can turn off tx and key radio and still have the pop pop .  One interesting thing is if I try to use the aux line input , din connector I have no audio . Yes I turn on the aux input , turn up the gain.
 Anyone know which path audio flows from back of radio to front? 
 I haven’t put a lot of time in schematic, it’s not the easiest to follow .  But I assume the audio goes through the center board ? To the cpu board. 
Any help would be great ! Thanks
