Afternoon Ian - Yes, it's one in the eye for those "Experts", who used to say, you would hardly tell the difference, between 1, 5 & 10 KW. OK it is a different situation for me than you, as I'm in West Suffolk. (in the car) I notice much less noise from the overhead phone & power lines, than when it was on low power. Once in the country, I notice very little difference. When I visit Gloucestershire, I really notice the difference - similar to yourself, with the added splatter from BBC5 in Droitwich - You can see the splatter on the Wooferton SDR, much the same on the Pullem Market SDR with the BBC5 TX near Norwich. It's amazing how the BBC get away with it - & they griped about Caroline's 963 splatter, in the early 1980s
Anyway - time for Sunday Tea
