indeed, first examine whether the BFO calibration is off - I think I see enough data (including my v4) that HFSignals does not align the BFO.? if all is okay here, then ...
[it would help a lot if HFSignals would list a 'default' BFO setting in the instructions!? maybe a v5 builder reading this will share their BFO setting]
my best guess is you have a connection issue somewhere.? (I certainly have made a bad solder joint before, and sometimes they are even attached!)
I would first check all the wires you installed, including insure you don't have a stray piece of wire causing a short across the RF.? Or it could be an audio issue also.?
A much smaller possibility - check more than one band in case it were an issue with board mounted filters or relays.?
Hang in their patiently - I sense its something simple.?
