IARU Monitoring System (IARUMS) Region 1 newsletter reports an increase in unidentified intruders in the amateur radio bands following Russia’s invasion of Ukraine
The newsletter notes:
Radars continue to be the most numerous and harmful intrusions in our bands. The OTR Contayner (RUS; BW = 12 kHz, 40 sps) tops the list of the most frequently received radars, followed by the Iranian OTHR radar, which broadcasts daily on 28.860 kHz (IRN; BW ca 45kHz; 150 and 313 sps bursts, alternating) and by the British OTH radar located at the Sovereign Base Area in Cyprus (G; BW = 20 kHz; 50 or 25 sps).
But also, coinciding the beginning of the war in Ukraine, these last months and also during May we have been receiving signals whose function we have not yet been able to identify. As these signals are unknown, we report them as “XXX”. The most common one has a bandwidth of about 8 kHz, seems to consist of a central carrier and is most frequently found in the 20 and 40 m bands.
