Okay I have the same issue with my Bitx40 and Qrp-labs Vfo combination. Currently I am running the vfo at 2khz below the desired frequency. Additionally when I transmit my ssb voice signal is clear about 1.6 khz below that. So I'm looking for some sort of adjustment for the BFO, and I see there is a spot for a variable cap that does not exist on the board. While I may have a problem with the VFO, (new software version chip on order) how do I correct the BFO issue? Do I need to add a trim cap to the bfo circuit??
