One of the knobs on one of my KX3s broke. Actually, it broke a while ago - it cracked, fell apart and disintegrated.
In the photograph, it would be the one on the left. Personally, I have been just "dealing with it". I turn the encoder shaft when I need to - no big deal, really.
However, my KX3s will be pressed into service for SPARC's Field Day effort (don't want the guys thinking that I keep a shoddy shack!), so this morning, I thought I'd fire off an e-mail to Elecraft, inquiring about a part number and price. I figured I would order two, one for the radio and one as a spare.
Within an hour of sending off my inquiry, I get a reply back that four are being sent at no charge. Wow. At the risk of being labeled an "Elecraft Fanboy", I think that's pretty darn neat, and that's all I'm going to say. I think Elecraft's actions speak more loudly than anything I can add.
