The best ID for me will be the exact frequency. Try having a signal generator exactly 10 Hz away, and measure the exact frequency shift on the spectrogram. If you have a decent timebase, with 1 ppm precision, you will see the DCF39 carrier on the right frequency +/- 0.1 Hz. >> Or, generate a calibration marker by using the second VFO tuned to WWVB on 60.000kHz and switch between the two at the touch of a button. If the spectrogram traces line up...etc etc. David
