Hi Dieter,
For FM you can exceed the 15.209 general limit of 150uV/meter @3m. See section
15.239. It allows 250uV/meter @3m. There are some bandwidth restrictions.
No license required, but transmitter Certification is needed.

Worldly Experts,
I just learned that Keysight has unceremoniously dropped calibration and repair
support for the 8546A EMI receiver.
It's an old beast, but we like it and use it a lot. Does anyone still use one
of these and know of a facility (preferably U.S.) that can calibrate them?

Robert,
Explain the FCC Rules to your customer and that while your equipment conforms
to the technical requirements, that is not always sufficient to prevent
interference in all cases. If their eyes haven't glazed over yet, you might
explain the effect of source-to-victim separation distance.
Worldly Experts,
I am trying to determine FCC requirements for a system that uses technology
similar to In-House BPL devices. The difference from BPL is that the data is
not carried on AC power lines. Rather it may be carried on other unshielded,
