Default Re: Military Radios PRC 638, TRA 967 & TRC 300 any info please?

I used to own a TRA967 - there is a very annoying sidetone that is transmitted with the audio - for the life of me I cannot remember the exact component I lifted, but from memory it was a preset pot inside the radio - lifting the wiper of this pot disabled the sidetone (essential for conversing with non military sets)

I think the wiring of the microphone connectors on these sets follow the same pattern as the Clansman range of equipment

Cheers
