Got a very strange beeping going right across HF every 50 to 100Khz in places and some places stronger than others! It's driving me mad and looks awful on my SDR, I can't pinpoint where it is coming from I have tried 3 different HF sets, switching off pcs and tvs so it must be coming from a source away from my house.
Anyone know what might cause this? there is around 2/3 seconds between each beep and a 5/6 second pause then starts again!
I have seen unusual interference like this before but usually at worst affecting 1 band say 1Mhz bandwith but this is everywhere I have so far looked (7-29Mhz).

I think you, or a neighbor, has acquired a plasma TV, cheap compact fluorescent bulbs, or a crappy wall-wart power supply for some gadget or another.
