finally after all the years running a stock 20A I¡¯ve done the voltage stabilizing mod and the varactor tuning mod with a 10turn pot, and I think I¡¯ve worked out the L7 windings now to get into the phone section of the band. But as a result, the band spread is only about 25khz.?
I remember doing a tuning mod on a sw40+ Using a 10turn pot and the bandspread was small. There I added capacitance in the VFO and get nearly 100khz band spread with a 10turn pot.?
I¡¯m thinking that by increasing C39 on the Bitx20A I should get more bandspread? ?Has anyone done this? I¡¯m I going in the right direction? I¡¯ll try it nevertheless but I didn¡¯t want to reinvent the wheel. Any guidance? Thanks!
