Alpha Mk10 wiring diagram

[harleygaz]

Hi. New to the forum so please forgive me if this has been asked before, I searched and didn't find anything. I have a problem with using an Alpha Mk10 with a GA radio. I have a converter (PILOT PA89 from Transair in the UK) but when I press that PTT I get a feedback that won't stop until I turn the radio off even when I release the PTT. I get the same with two RAF cloth helmets so I don't see it being the helmet itself. I have somebody who can look at it but he has asked me for a wiring diagram for the Alpha and the web didn't get me anything. Can anybody help? Cheers Gary (ex pat Englishman living in the US)

Although you have a converter you might still need to investigate changing the comms to civvy ones to match the impedance.
