I wired up my transponder to the altitude encoder today. Involves crimping the molex connector at the back of my Narco AT50 transponder to the encoder, which came pre-wired.
I know the transponder is operational as I recently got it tagged.. but I have no way of testing it... not near any airfields out here. One thing.. when I turn it on, it emits a very high pitch tone.. like a squeak.. quite soft, but doesn't stop.
Honestly, I've never turned a transponder on without an engine running, so have no idea if this is normal... anyone know anything about the Narco ?
ThanksStuart
PS - pretty sure the wiring is good.. have both encoder and xpdr installation manuals, and it seemed basic enough.
