Thank you , Jerry.
I am going to try a completly new mike, including the wires to the jumper on the main board.
I also thought that I could try a CW transmission test if I wire up the CW keyer. ???
PS with regards to the Pop sound that when transmitting, it is not as loud as it used to be.
When i key the PTT it does switch off the receiving and I can hear a sort of a click sound as the speaker goes quiet.
I suppos this is because the audio transmitt is not making it through.
Thank you for your help so far.
I am a beginner on the electronics side with only self taught skills.
