What happens when you transmit CW?

Have you joined the Kenwood Hybrids .io discussion forum? They can fix anything and everything!

good day to you,thanks reply
in cw i have full output, no problem there
with the mike gain fully cw, thus max gain i need a firm wisthle to obtain full output,
mike gain at 10 o clock gives a 10 watts output with a firm wisthle,
not responding to voice like its should be.

seems there is something in te circuit thats attenuating the mike signal

Is the mic itself ok I wonder?I have had one Trio mic fail last year.

Does operating the PROC switch a few times have any effect?

hi, solved, oxidized processor switch, deoxit has done the job,
full output now in voice, very sensitive now.
thanks to all and martin who came with the golden tip about the processor switch.
