KY97A Problem

[Continental Bill]

Hey guys,

I've got a KY97A that quit working. It lights up, shows frequencys
and switches frequencys and when I hit the push to talk button the
little "TX" comes on. I can hear the external speaker pop when I hit
the push to talk but it won't transmit or receive. If I have my hand
held in the cockpit while I'm keying the mike I can hear what sounds
like a carrier but nothing else. When I pull the "test" button there
is no squelch override and no characteristic static. The other radio
in the stack (a KX170B) works just fine.

I fiddled around checking connections, disconnected and cleaned the
antenna leads, pulled the radio out, checked connections there, pulled
the audio panel (a KA134) and looked at those connections, everything
looks fine. I'm thinking it's in the radio itself. What do you guys
think?

Hi Bill,
had a similar problem that was simply one of the jack wires not insulated
correctly and it crossed and earthed out, no damage but no signal either.
