Radio 538 (from the Netherlands, the number in the name is a tribute to the original Radio Veronica wavelenght, in the seventies) confirmed my reception on 1st August 2011, at 00.05 UTC on 891 kHz, by filling the above PFC. So, we learn that the transmitting site is Hulsberg, with an output of 20 kW. In the envelope I received there was also a QSL letter, along with an information sheet on the station (which has a huge network of FM transmitters in the Netherlands, on the national channel of 102 MHz, and only 891 kHz as MW frequency). Report was sent a few days after the reception, via surface mail. Answer came yesterday, 16th September, and verie signer is Mr. Rene van de Kolk, broadcast engineer for the station. Thanks a lot, Radio 538!
