I'm making room in the shack and collecting cash by selling one of my two K2s on eBay. I'm the second owner for this unit, which was professionally built and has, I think, every option possible from Elecraft including the KSB2, KNB2, KIO2, KDSP2, K160RX and K60XV.
For the record the serial no. is 02445 and the firmware is rev 2.04P/1.09. It has the AF pot mod also. The rubber band thingee on the tuning knob was there when I got the rig. It's easy to remove if you don't like it.
My XYL is carrying the radio on her trip to Chicago next week and will ship the radio to the winning bidder from there. Shipping will be free in the U.S. If you are outside the U.S. and win the rig, email me directly for arrangements to ship it to you. I'll deduct $30 from the actual shipping costs for non-U.S. shipment.
