Anyone have a schematic for the handset for the TRA 931 set? The number on mine is 5965-99-901-4616. I think mine is wired wrong.
Thanks.

Bruce, it should be in the manual. Look for the Audio socket connections diagram.

F is earpiece
A microphone
C PTT switch
D common return for all those

I did buy some handsets from ebay however that had the correct plug on them, looked like the correct handset however they were wired differently, but it is easy enough to check with an ohmeter...

Bruce, I should have looked in the box. Yes those are the same numbers that are on the handsets I have here. They are wired differently, but can be easily converted to work with the Racal radios. I have no idea what they were used for originally, but you are right, they don't work as they stand.

I know this has been mooted before but has anyone made an adaptor lead between the 931 anhd the Clansman series? Are the insert impedances and keying schemes interoperable?
