I'm nearing the completion of my K2 (#6991); I finished phase 2 of the RF board this week, completed the alignment, and last night I was able to hear some CW on 40m with just 10' of speaker wire as an antenna. Hopefully I've have it completely done in the next 1-2 weeks.
I'm already thinking about some possible improvements. I have an external tuner and an external amp. I built an RF sense switch for the amp which will key it when I'm transmitting, but I still have to manually change bands on it. This was fine for my first rig, a 40m-only QRP transceiver. But it would be cool if each time I used the Band + and Band - buttons on the K2, it changed the band setting on the amp. The amp has an input for this, I would just need to build something that can trigger it. The question is, how would I trigger this from the K2? What's the best way to capture the band change events? Use the serial interface? Hard-wire something to the band change buttons? The tuner might be simpler or might not be. Is there any way I can use the Tune button on the front panel to control an external tuner? Thanks in advance for any insights! -- Owen B.
