Re: 80 Meters on BITX40?


 

Yep, a filter bypass is dirty, but it works! I'll be using a QRP Labs 80m filter. I think I have devised a way to make it very easy to insert into the circuit with nothing but a switch to choose the filter. I need to do some experimenting though. I'll post information when I have it. The stock LPF should be okay though since the next harmonic when running the vfo down to 3.8-3.99mhz should be over 8mhz, which is above what he LPF lets through.?
