Re: Odd FT8 transmit behavior #ubitx-help

CW transmit still works so I haven't blown out the power chain (yet!).  I'm starting the think I need to run through calibration.  Maybe the IF filtering that is supposed to suppress the carrier is misaligned and the carrier is landing in the pass band.  That would also explain the weak side-band which might be getting pushed into the skirt of the band-pass filter.  Hopefully, someone who knows the design better can chime in and confirm or blow a hole in my theory!
