No, DCF39 is an FSK transmission, so after a burst of data the resulting
carrier phase will settle to some random new value. Look at the DCF
77.5kHz transmission for a phase stable signal, or try for MSF on 60kHz.
I'll be sending a 10s PSK CW message tonight, from 1900z on 137.450000kHz.
May be some signals before that, but any data timing will be sychronised to
1900.00z

instrument. I will put my spectrumanalyzer into the junkbox!
clearly visible the phase jumps after the bursts from DCF39.
is it intentionally or depending on a technical fault?
see attachment.
