John and co. I've just been talking to Roger GW3UEP in SW Wales and he is receiving the noise very well all day long. This corroborates the "good" reception by Terry who is about 30 miles North. How

Hi John - I'm seeing a 5dB increase in the "noise floor" between 498 and 502 kHz but only after dark (measurement taken at 2300 utc). Location is Watford (IO91TP). Receiver is Winrad Excalibur SDR. B

First I thought it was a lack of receiving conditions here. But the noise band also appeared on WebSDR Delft. Some Googling it appears this to be a NATO test transmission for Marine data. Doc found o
