Having experienced something like this last year, a fried eggs sizzling noise I tried many recommendations. BTW, our utilities are underground. Eliminate your house as the source of the problem by running your rig from a battery and shut off the house circuit breakers, everything. Don't overlook a bad PC UPS and poor wall wart power supplies.
Ok, maybe the noise is not in your house, now put your hiking boots on and walk the neighborhood with headphones, a FT817 and whip antenna. Someone told me that AM on 138Mhz was best for finding noise, I cannot be sure of that but I sure did find a lot of weird stuff, houses making buzzing noises, street intersections with screeching noises .... It actually became very interesting and confusing. I put many nights into walking the neighborhood and beyond since none of the noises I heard to date traveled very far. Suddenly the noise at my rig went away and never returned. I can only imagine it was a neighbors electric blanket or fish tank heater ... or maybe something caught fire and burnt itself out. Anyway, I won't miss poking at around houses with the whip to seek out electrical noises.
