ARLA/CLUSTER: Aumento do QRM na banda dos 40m devidos aos radares OTH russos

[João Costa > CT1FBF]

Major QRM on 40 metres

This week's SARL News say European and South American radio amateurs
have reported major interference from Russian OTH Radar stations
(Over-the-Horizon Radar stations). Interference has been reported on 7
064, 7 109, 7 170 and 7 190 kHz. All signals are 12 kHz wide.

Several European Societies have already sent complaints to the
Regulator in their country. The SARL needs reports from South African
radio amateurs before the SARL can report the intruders in the amateur
bands to ICASA for appropriate action.

The interference is problematic as in the ITU Convention Chapter VII
Special Provisions for Radio; Article 48, states "...Installations for
National Defence Services: Member States retain their entire freedom
with regard to military radio installations!"

It is however important for as many amateur radio associations as
possible to send complaints to their local regulator. Please monitor 7
064, 7 109 , 7 170 and 7 190 kHz and send your observations i.e. date,
time, frequency and signal strength (S meter reading) to
artoday  sarl.org.za.

Help us to protect our frequencies.
