1)? ? ??I tried calibrating by injecting an unmodulated carrier 10.000,000.00 MHz (GPSDO) at 70 uVrms into antenna port and used DL4YHF¡¯s freebee audio spectrum analyzer software.? First I tried it on LSB listening at 10,001.000 with Ubitx and after entering Calibration mode, by adjusting encoder until the carrier tone was at 1000 Hz on the audio SA.? I slowly pressed in encoder knob but as soon as that happend the 1kHz tone on the SA jumper 500 Hz to where I had started.? I did this several times same result.? So, next I changed to UBitx to USB listening at 9.999,000 and after entering Setup Calibration I again adjusted the encoder using the audio SA to hit 1kHz on the head. but as soon as I pushed in encoder to save, the 1khz tone had shifted back to starting point. For the LSB adjustment the optimum Calibrate setting was 15-16 and for USB it was -4 to -5.? (I may have written these in reverse here, don't have my notes).? ?Another strange thing is BFO adjustment... with CEC each time I enter BFO it shows a value of zero.? For LSN I need to crank it up to about 2300-2400 to hear a nice clear SSB QSO.? ?However as soon as I? cycle power - it forgets the previous BFO setting, sounds terrrible and I have to reset BFO back to 2300.
Any advice appreciated
