As mentioned previously, Alan W3DVX of Wilcox Engineering, has my K2 at the moment.
I heard from him the other day. He's got the frequency readout and the filters aligned. He fixed my BFO problem where I was hearing both sidebands of a signal.
He's at the point of installing the KAF2 and has run into a problem. When the KAF2 is installed, it messes up the operation of the KAT2 auto tuner that I built and installed last year. I should have my K2 back this week, hopefully, all professionally tweaked, aligned and ready to go!
