[DX] Etiopialaista häiriköintiä
RSGB (Englannin radioamatööriliitto) tiedottaa Etiopian aiheuttamista häiriöistä
hamssi- ja muillakin bandeilla:
[quote] If you regularly listen into the new 7100 - 7200kHz range in the evening
hours, then you may have noticed some interference. Starting 1630UTC and lasting
about one hour, you will find on 7165kHz, or sometimes on 7175kHz, a powerful
wideband rushing noise, which is some 15kHz wide. Also very faintly you can hear
the carrier of a program below the jammer.
The culprit is Radio Ethiopia. It is jamming Voice of the Broad Masses from
Eritrea on 7165kHz. Ethiopia also regularly jams other transmissions in Amharic,
for example Deutsche Welle, on 15 and 11MHz. The jamming uses a rectangular
white noise signal that is some 10 to 16kHz wide. In 2008 Ethiopia commissioned
3 or 4 new transmitters, some of which are regularly used for jamming unwanted
programmes. To see a screen shot of the jamming signal, check out the IRY Region
1 website. [/quote]
Täälläpäin kuuluu R.Etiopia 9704 kHz iltaisin, melko selkeästi, mutta heikosti
(S=1) ja naapuritaajuuksien puristuksessa.
