The International Amateur Radio Union Region 1 Monitoring System (IARUMS) April
newsletter[1] chronicles a plethora of intruding signals heard on exclusive
Amateur Radio allocations in Europe and Africa, many of these also affecting
the bands in IARU Regions 1 and 3.
The most significant interfering signals originate from over-the-horizon (OTH)
radars in China and Russia and affect 40, 30, 20, and 15 meters.
The newsletter also recounts monitoring stations' reports of voice traffic on
several bands from fishing operations in various parts of the world, telemetry
from marine buoys, and persistent taxi dispatching traffic from Russia on 10
meters.
Other interference has stemmed from broadcasters - harmonic-challenged and
otherwise - as well as from jamming signals attempting to prevent broadcasts
from reaching their intended audience. Pirate (ie, unlicensed) stations have
been reported on 80 meters and elsewhere, and Russian digital military traffic
has been monitored on 40 and 20 meters.
OTH radar interference prevails, however. IARUMS Region 1 Coordinator Wolf
Hadel, DK2OM, documented a Chinese OTH radar occupying considerable swaths of
spectrum on several bands. IARU Region 1 maintains the world's most active
network of volunteer intruder monitors.
