4600 turbo with the 2290’s receive is good,has dead key no modulation. The T/R light turns orange not red when keyed. I’ve checked tr38, mic IC, D77 etc. any ideas on problem appreciated.
Am/fm/pa switch itself, wiring, cold solder joints, solder blobs?4600 turbo with the 2290’s receive is good,has dead key no modulation. The T/R light turns orange not red when keyed. I’ve checked tr38, mic IC, D77 etc. any ideas on problem appreciated.
Am/pa switch working. No solder blobs comes the board with the magnifying glass. Something keeping it from fully going into transmit. Am/fm/pa switch itself, wiring, cold solder joints, solder blobs?
That's where I'd go next but let's see what the more educated say
When it does that, then you KNOW there is an issue with the keying circuit.Pulled tr32 and it came to life but light is still orange.
