As many are aware I removed a perfectly good... working KT78A Transponder and tray from my Aerobat when I installed the Appareo ESGi. I also have the Altitude Encoder which was working as well. I had no problems with either unit.
$200 + Shipping for the KT78A
$50.00 + Shipping for the encoder.
Offers accepted.
