Hi Jerry and Allard,
I was hoping you two would chime in. I chose the uBITX sketch for several reasons: 1) already has band switching 2) already has rotary encoder 3) already has BFO 4) wanted the challenge of making it work on an Uno R3 and i2c LCD. I *think* I have the nuts and bolts of all those things correct but I'm just missing something somewhere else. I'll do a bit more testing and possibly a video to describe it, and get back to you.
