The low moon this evening allowed me to sight along the dish feed, with the feed just above my head. When I went back into the shack there was an enormous noise burst on the P3 display.‘Funny’!Went back out and repeated it and, again, a big noise burst.Then the penny dropped.I occasionally wear a pair of Widex hearing aids. The sort that talk to each other via short range radio.These obviously produce a lot of noise in the 23cm band, that is only obvious when close to the dish.
That’s a new interference source on me!
I will be at Friedrichshafen Ham Radio and plan to be at the QSL wall at 13:00 on Friday. I hope to see some of you there. You may be able to df me on 23cm by looking for the noise from my aids.............
