For sale KRC2. Worked well with my K3. I sold my K3 and the KRC2 does not work with my Kenwood TS-590. This is a sale as is as I have no way if testing the unit. It was working with my K3 a year ago but your experience might differ. What I mean is that for questions how to make it work with the K3 or any other rig you are on your own. 73 Maarten N1DZ
