Hi John and LF Group, here is the result from last night's recording of John's slow PSK transmission: This ultra-narrow spectrogram has a resolution of 0.329 milliHertz (16 times finer than Argo 120), and the duration is 13.2 hours. The wandering and fading central line is Loran GRI 8000 from Russia, with my receiver drifting up and down by about 3.5 mHz. Between 3:45 and 5:45, the line is accompanied by +- 0.56 mHz sidebands; these are John's PSK transmission with 30 minute modulation period. 73, and thank you for the interesting experiment Markus, DF6NM
