As I suspected, both events occur at the same time. The kiwiSDR signal is delayed by a few seconds as the data is uploaded and back down again. An extraction fan of sorts, and then something else kicks in? It's almost like a gas boiler and vent tur…

I think I have found the source. I noticed last night a neighbours extractor fan (that was never previously used) is blasting out air. It was on when the interference was there this morning, and now that I'm home I've checked again to find the fan i…

Continuing to update this thread, so there is a proper history. I did report to OFCOM as it was a quick and easy thing to do online, although I did take your post on board @Powernumpty. They were willing to help if I could specify up to three spot …

I've captured the signal as it first started today, just after 6pm. I haven't noticed anything significant at the time the interference appeared. The street lights are still off, the emergency lights in the hallway are already on. There's no spotlig…

I've gone for a walk like @Powernumpty suggested, with headphones and a radio tuned into 20MHz. The interference was obvious. Turns out the problem is very local to me. Within 4 houses. So it's something in a neighbours house. I'll be keeping an eye…

It is stopping me from continuing the hobby of monitoring my own radio signals, and allowing me to look at varying digital signals to decode and investigate and understand, etc. But not sure if that'd be enough for OFCOM help. Not going down that ro…

Thanks @elitedata That's good info to have for future problem solving. However I have done some investigating, it's not the KiwiSDR or the mag loop antenna that's creating an issue. The KiwiSDR is actually doing an excellent job of doing what it's s…

Well it's not the KiwiSDR or the Mag Loop that's the issue. I've tried an AirSpy and a HackRF using the basic ANT500 telescopic antenna, and the switching signal is everywhere below 73MHz. I don't see it anywhere higher than that, so that's somethin…

To answer some of the comments so far: It seems consistent day or night as far as I have witnessed myself. The YouTube video was just after midnight. I'm looking at it now at 14.45hrs and it's the same. At present I cannot rotate the antenna as it …
