[Elecraft] Noise, RFI ?

[Phil Hystad]

All of our electricity comes out of the ground.  Everything is underground here except for a few poles a number of blocks away.  I have heard that kind of noise before from insulators (dirt, carbon, etc.) and this is definitely not that.

Besides, that would just not have this exact on off switching behavior as if some tool were being used.

If not that, then you might want to check for carbon trails on HV insulators along the road (usually very effected by the weather). As a third guess - and a worst case scenario - a serious problem in your home electrical system (or a nearby neighbor).
