Title: Scrambled 21.2 MHz HF Comms out of Europe?
Post by: Sky on May 30, 2023, 1422 UTC

The 15 meter amateur band is open to Europe this morning.  Worked a station from Croatia with strong signals.  Hearing some apparently scrambled voice traffic on the 15m amateur band.  Seems to be LSB but wideband at 6-10 kHz bandwidth.  The language is perhaps Romanian or some other latin or slavic based.  There is a lot of conversation.  Almost sounds like a full duplex phone conversation of split frequencies.  Anyone know what this is.  73. Sky, Az.

About 21.155 MHz at this time.  Sounds like a female voice with a lot of short conversation.

15:37 UTC - I am hearing a male voice on 21155.0 kHz USB via the University of Twente Wide-band WebSDR but it sounds more like a "CQ CQ CQ this is" ... in a foreign language.
15:40 UTC - Multiple stations, definitly amateur radio oriented.
