jamming I didn't hear it. 11645KIG was also audible at fair strength and
jammed. WHRI was very good on 15665 - I assume it was this one on 13650 at
1500 (as sched on Sundays) and in Russian.

15665 WHRA QRM was Sat/Sun 17/18th, 1300-1500 27-29,37-39 HRA 250kW 60degr
There was no trace of WHRI on 15665 today (19th) so maybe that is a
weekend transmission only - same as the one on 13650?
As Wolfgang wrote earlier - the jamming noise affecting the D.Welle at
1400+ UT today was something different on both 11645 and 15645/15640 kHz.
A carrier came onto 15645 kHz before the noise started so maybe that was
the jammer, and the noise spread across 15640? My own comment about the
sound - written before I saw Wolfgangs - was a 'pulsing, oscillating,
squeaking noise'!

BBC_Monitoring (BBC_M) can confirm that two major Western broadcasters are
suffering consistent jamming of their transmissions to Ethiopia. Jamming
is deliberate interference aimed at preventing the target broadcast from
being heard. The standard technique is to transmit an irritating noise or
continuous music on the same channel as the target.
In the latest media development to hit the Horn of Africa, the scene of
numerous "radio wars" over the past quarter-century, shortwave broadcasts
>from Washington-based Voice of America (VOA) and Germany's Deutsche Welle
(DW) are now being jammed.
In both cases, the target of the jamming is radio programmes in Amharic,
the lingua franca and main official language of Ethiopia. VOA is also
suffering jamming of another of its regional language services. The
deliberate interference appears to have started in the first half of this
month, possibly on or around 12 November.
VOA and Cologne-based DW are funded by the US and German governments to
broadcast radio and TV programmes to foreign audiences. The moves against
the VOA and DW follow intensification by Ethiopia of its jamming of
broadcasts from neighbouring Eritrea. The jamming of Eritrean state radio,
the latest episode of which began in summer 2007, was stepped up in late
September and early October, BBC_M observed at the time.
Details of the jammed broadcasts.
The VOA's daily one-hour (1800-1900) service in Amharic is now being
jammed. According to the opposition website Ethiopian Review -
- the jamming of VOA began on 12 November. BBC_M observations have
confirmed the presence of jamming signals on at least three of the five
frequencies used by the VOA. The direction whence the jamming originates
(established by the use of directional aerials) is consistent with the
signals being transmitted from within Ethiopia.
VOA currently uses 9320, 9860, 11675, 11905 and 13870 kHz for its Amharic
service. The service is not streamed on the Internet, but audio of recent
broadcasts is available at
On 19 November, VOA's service in another major Ethiopian language, Oromo,
was also observed to be jammed. VOA's Oromo service broadcasts at 1730-
1800, immediately before the Amharic transmission and on the same
frequencies.
DW's daily one-hour (1400-1500) service in Amharic is also being jammed.
