The method that I use to calibrate the frequency of my K3 is to use 2.5, 5, 10, and 15 MHz WWV as calibration signals and adjust CONFIG | REF CAL on cw so that the signals are as close to 600 Hz as possible as measured in multipsk's spectrum display in psk31, highlighting the WWV frequency and reading the audio frequency of the spectrum line in multipsk's RX frequency text display. Because of the way the K3 generates its signals, the calibration varies from band to band but I can easily keep the K3 within +/- 1 HZ using this method. I have settings for each of these WWV frequencies in memory on adjacent memory settings so I can check them momentarily once I've clicked M>V once quickly without needing to click M>V a second time.
I'm a paid multipsk customer but it's a free download at the level needed to do this.
