My 6700 is 50 Hz off frequency, no big deal, but can this be adjusted or calibrated out using a known accurate souce and if so, how?

    How did you measure the 50 Hz?

    Hello Chris

    By listening to WWV on 15 mHz and measuring the audio off beat or difference from zero beat, using a frequency meter.

    There is a calibration utility in the radio settings. Settings / Radio Setup / Receive / Frequency Offset

    Hello Peter, I think Chris wants to ensure that you are truly off calibration by that much. The clock in the 6700 is specified at 0.02 ppm (stability) while your offset is >3 ppm. That is a rather large difference. I'm not saying this couldn't happen, but you might want to check by another means. I use FLdigi and its frequency analysis mode. During the last ARRL Freq Measurement Test my setup was within 0.04 Hz. ( I do have the GPSDO option.)
