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.
