Receive audio is great.


I just replaced c550 and still same problem.

If I say Ah in to mike normal voice nothing but if i YELL AHHH in to mike the mod meter external dosy will move up 30-40%


Tried 5 good mikes and all the same results.


So it seems its not getting any modulation amplification with the output carrier modulation is there but no amplification. Racking my brains out , replaced tr10 13 and 17 in local area and same problem.
