Thanks Don. I do have the RE installed. This was a fully functional
K2/100 with all internal options that has  been in storage for several
years. I'm dusting it off and going through it thoroughly, from a
factory reset. That explains the D19 = Y problem. It has a couple of
other problems, notably bad AGC (can't set up S-Meter LO and HI
properly), and "dead" on receive. Step at a time.

Thanks again, Don.
