The microwave aspect could be quickly cleared down by checking with of
those cheap microwave oven 'leak detectors'. Personally, healthwise,
I'd be a bit worried about the effects of not being able to stay in
the same room when the 'ultrasonics' are coming on mode. OTT ;-) but
there's a couple of cold war echoes here with the U.S embassy in
Moscow, being irradiated with high power microwaves, in an effort to
excite natural resonant cavities in the structure, at a level
sufficient enough to cause the staff to suffer from various radiation
linked illnesses. Any airports, military installations within a 25
mile radius?. Maybe you're catching some very preferentially
reflected, sidelobe illumination?.
