Oh, one other point I wanted to make.

Typically, from the house next door, a device that complies with Part
15 will be about S7 on HF. If hams know of devices that are
significantly louder than that, I would like to test them. If you
can, provide me with a model number and source and/or the unit itself,
which I can return to you.
