Grimeton SAQ 20190630

Grimeton Radio SAQ on 17.2 kHz received at Alexanderson Day Jun 30 2019 12:00 UTC. QTH: SQ5BPF Warsaw/Poland KO02md
Please watch in high quality to see the time markers on the spectrogram clearly. The time markers are in local time, so substract 2 hours to get UTC.
At the beginning you can see 3 active CW stations at the same time: SAQ at 17.2kHz, RDL at 18.1kHz and RDL at 21.1kHz. Both of the RDL stations transmit DFCW (the higher frequency is the Mark frequency).
The sound is not very well synchronized unfortunately, especially at the end of the transmission.
Video from the transmission at 9:00 UTC is avaliable here: • Grimeton SAQ 20190630 ...
