I ordered a fully-loaded KX3 today. The Elecraft Web site lists everything ordered as being in-stock so I hope to see it sometime late next week. The transceiver is an excellent performer and has been around long enough to have worked out all the kinks.
In fact, my only reticence about ordering one at this point is that given it’s been out for more than five years, I can just imagine Elecraft announcing a replacement for it at Visalia or Dayton in a few months.
I didn’t order the amplifier or the panadapter. Either or both could be added easily enough at a later date but the panadapter seems to me a feature coveted by DX chasers but unnecessary for casual operation.
It’s much more likely that I’ll add the 100 watt amplifier around the time the weather breaks and it turns again to antenna season.
