Re RFI: i lived for some years in a travel trailer on property. One winter the power went out and stayed out for a week.

I survived with not too much work because i could use my vehicle to charge up the trailer’s battery, i had propane heat,

and the well had pressure so water was available without any pump. Anyway, to the point: NO RFI. Even with a transistor

portable radio with a whip antenna, i could hear a “Lowfer”  experimenter ‘Part 15’ transmitter on the 160 kHz band, 1 watt,

MANY miles away. Quite a revelation.
