ARLA/CLUSTER: Batalha nos 40m (7 MHz) entre as Radio Eritreia e Radio Etiopia

Broadcasters, jammers wreak havoc on ham radio frequencies

The ARRL reports the battle in the amateur radio 7 MHz band continues
between Radio Eritrea and Radio Ethiopia, which is said to be jamming the
Eritrean broadcaster with broadband white noise

The problem for radio amateurs is that the battle is taking place in the 40
meter phone band — 7.145 and 7.175 MHz — with the jamming signal reported
by the IARU Region 1 Monitoring System (IARUMS) to be 20 kHz wide on each
channel.

The on-air conflict has been going on for years; Ethiopia constructed new
transmitting sites in 2008 and is said to use two or three of them for
jamming purposes. The interfering signals can be heard in North America
after dark. According to IARUMS Region 1 Coordinator Wolf Hadel, DK2OM,
Radio Eritrea is airing separate programs on each frequency.
He said in the IARUMS September newsletter that telecommunications
regulators in Germany, Austria, and Switzerland have been informed, so they
could file official complaints.
