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 ...

Nigerian fishery on 21 MHz - reported by DJ9KR

Dear fellow Intruder Busters,
Every day you can hear Nigerian fishery on 21002 kHz in SSB-USB. I have first heard them on 15 September from 1740 - 1812, and last today 21 September at 1700 UTC. 
The fishermen speak a local dialect and also quite well French. They have told me that they are Nigerian fishermen, ship name "VOLOCAN-3", and that they are fishing in Cameroon waters. Please activate the QRG with CW.
