Is it a KT76 or a KT76A? I just took my KT76 in because it "received" but
did not transmit.
They put it on the bench and 260watts output but at the wrong freq(just
adjustment). I believe the
KT76A is more reliable than the KT76 for stability. Anyway, $175 later it's
in the plane
but not tested yet. It needed some service bulletins performed also....

Hey all... finally got around to taking a trip in my plane this
weekend (busy with school stuff). The transponder appears to be weak and
the controllers were none-too-pleased without seeing a squawk, IFR,
running next to a TFR... They had a tough time receiving my squawk,
especially when far out. I saw the blinky-blinky interrogate light
lighting up just as normal, though. I just (June) took it in for IFR cert
and they said it was all fine.

I thought it might be disconnected antenna or dirt on it, but the
BNC connector looks new and antenna was slick and clean. I'm assuming
this thing is old enough to have a tube output that might be losing power?
I think I will first try replacing the antenna and entire coax run... it's
cheap and easy to do.... just looking for other thoughts.
