Listen to these samples via the IBB RMS receiver in Addis Ababa on 10
March:
1) VOA Amharic mostly in the clear at 1817 UTC on 11905 kHz, but
2) mostly covered by jamming on that frequency by 1844. Also at 1844:
3) covered on 11675,
4) getting through a bit on 9860,
5) some background audio on 9485, and
6) covered on 9320. It seems the jammers are winning. (The only VOA
Amharic transmission is at 1800-1900 UT.)
To combat jamming, the best remedy is to transmit on as many frequencies
as possible, from as many azimuths as possible. The closure of the IBB
relay stations in Morocco and Greece has not been helpful in this regard.
Transmitters for lease will have to be found. Posted: 11 Mar 2010.

It also helps to use higher frequencies if they will propagate but that is
9-10 pm in Ethiopia (by the western clock), since that increases the skip
distance the jammers have to transit.
I still wonder how effective jamming on 25 and 31 mb is within Ethiopia,
much of which would be in the skip zone if the jammers are really around
Addis. Could they be getting help from some other country at a betterpositioned
one-hop distance?
