Well I just managed to score a pristine KX3 on eBay for $1400, and will likely win the bidding for a new Panadapter PX3 for another $400. I hope I made a wise purchase:
S/N 5378 was bought brand new by me and has never been in the field. Everything with this radio was factory assembled except for the heat sink and side plates which I installed. I have used it exclusively for digital modes and it served as my base station. It is in perfect condition and everything works correctly. I also purchased the Elecraft KX3 paddles and the Nifty desk stand. It has all filter, a charger and clock. I am a non-smoker and this radio is in excellent condition. I am also including the power cord and the original Elecraft shipping box.Also included is Fred Cady's "The Elecraft KX3 Portable"220 page booklet. It has also had the factory "KX3 VFO Temperature Compensation" procedure done to reduce VFO errors in digital mode.
