Voice of Russia on 7200 kHz

DJ9KR reports: Since February 1st, 2011 the Russian BC Radio Station "Golos Rossiye" (= Voice of Russia) is transmitting programs in Russian language on the exclusive Amateur Radio frequency 7200 kHz with quite high power. This is causing very harmful interference to the Amateur Radio Service world wide, which has an exclusive allocation for the range 7000 - 7200 kHz. The location of the transmitter is St. Petersburg, RUS.  The transmissions are from 0800 - 1500 UTC with S9+35dB in my shack. My antenna is a dipole.  Please inform your National telecoms. authorities and invite them to write an "International Complaint". I have already sent an email and a fax to the Embassy of the Russian Federation in Berlin. Also I have made a phone call ( 0049 - 30 - 229 - 11 10 " or "0049 - 30 - 229 - 11 29 ".

Weatherfax on 40 m disabled

PA0GRU and DK2OM observed a strong weatherfax transmission on 7101.9 kHz on Jan. 7th 2011 at 0930 UTC. Parameters: 120 rpm, IOC 576. DK2OM was able  to identify the source of transmission and phoned the German PTT at Konstanz. The location of the transmitter was Northwood, UK. The German PTT took bearings and phoned the British PTT. After 1 hour the fax transmission left our 40 m-band. It must have been a frequency tuning error in Northwood. Anyway: A fast success for IARUMS Region 1! Many thanks to Dick, PA0GRU, Uli, DJ9KR, the German PTT (BNetzA) at Konstanz and Ofcom Baldock, UK. More details ...
