IARU Region 1 Monitoring Service reports an apparent success

The International Amateur Radio Union Region 1 (IARU-R1) Monitoring
System (IARUMS) reports that the Russian military apparently responded
positively to a complaint from German telecommunications authorities
to eliminate an intruding signal on 20 meters.

The Russian Navy "RDL" signal from Crimea had been transmitting on
14.180 MHz, using F1B at 50 baud and 200 Hz shift for several days.

IARUMS said the transmissions were heard for the last time on October
31. IARU Region 1 includes Europe and Africa.

German telecommunication authorities have, so far, had less success in
quelling the intrusion of Radio Eritrea (Voice of the Broad

Masses) on 7.185 MHz, which Ethiopia is said to be jamming with
broadband white noise. So far, Germany has filed two official
complaints. IARUMS reports that 7.146.5 MHz and 7.175 MHz are still in
use by Radio Eritrea. The jamming signal reported by the IARUMS is 20
kHz wide on each channel. The on-air conflict has been going on for
years, and the interfering signals can be heard in North America after
dark.

IARUMS Coordinator Wolf Hadel, DK2OM, said the Russian
Over-the-Horizon radar (OTH) "Konteyner RLS" remains a problem on 40
and 20 meters, with lengthy transmissions, often with many spurious
emissions. Hadel said the radar's transmissions interfered with
participants in the Worked All Germany Contest in mid-October.

One apparently frustrated radio amateur in Germany "tried again to
chase away Russian MIL FSK traffic on 80 and 40 meters by transmitting
dashes on the mark or space frequency," the latest IARUMS newsletter
reported. Hadel cautioned that such actions, even when aimed at
intruding signals, are illegal. German telecommunications authorities
were alerted. IARUMS also reported someone was transmitting empty
Stanag 4285 mode signals on 7 MHz, hunting and QRMing German
contesters on October 29. That signal was also believed to be
originating in Germany. The Stanag 4285 modem is used for HF radio
links between the NATO military bases.

IARUMS also reported an OTH radio on 10 meters, transmitting daily on
28.960 MHz covering about 50 kHz "with many spurious emissions."

Strong F2 propagation has also made Brazilian CBers audible on 10
meters, running AM between 28.000 and 28.325 MHz.
