Title: RU Mil 6481 USB 0911 UTC 28 Apr 2023
Post by: kris on April 28, 2023, 1342 UTC

0911 Just before S11a starts transmitting 0915 UTC on the 6480, the other W Ru (live) operator calls:
         90 282  ja 22 302 pryiom
0920 after activity S11a, the W Ru operator  repeats the call - signal level just above noise, no response

   Hi Manfred - you're right - from 6481.8 up it constantly occupies 3kHz digi UT and its emission was not interrupted during the broadcasting of the stations of interest to us.
Despite this, the signal of the Russian operator was clear to me.
   During my previous session of listening to this channel, I saw and heard some words but it was the end
and I was so surprised that I did not understand anything.
The Russians, however, are heard about 5 min before and after the transmission of the S11a station.
The coincidence of the broadcast time and the proximity of the FRQ is puzzling whether this is a coincidence or a deliberate action by the Russians.
