Re: BITX40 build for SOTA/POTA operation

Very nice! I like that arrangement even better than the one I linked to. Question: how did you anchor the plate everything is mounted to to the case?

Re: 80 Meters on BITX40?
Further to the LPF modification for 80m, I have done more experimenting and found that if you switch in a 470pf cap across L6 in the LPF, you will get about 37db attenuation on 40m, with a nice

Re: raduino v1.27 released (improved suppression of spurious burst)
Hmm, maybe possible. But this would take extra program space and we're already tight. I want to implement digital BFO first (v2) which also needs some space. If we would have 4 VFO's then we also need
