Reception of continuous wave signal from the old 🇨🇳 🛰 FengYun-1D on 480.019 MHz, with strong QRM on 480 MHz from the USB port, where my @airspy_com R2 sdr was connected. Besides, there is DVB-T tv channel 22, centered on 482 MHz (from 478 MHz to 486 MHz). Replay of recorded IQ.

Russian Pacific Fleet HF intercept: voice hail on 8439 kHz negotiates a shift to 9100 kHz, followed by FSK 300Bd/500Hz data bursts. Roles of callsigns Greyder/Volnoboy seem to suggest a doctrine that inverts NATO's FAB/BRASS model.

Installed my TinyGS station in Oreoi on Evia. The station is receiving nearly 1500 packets in 24 h.
