I wasn't making a value judgement but merely putting this on the CHA record
to raise awareness of the situation. The topic has arisen a few times here
and elsewhere. The first incident I recall was around Homestead AFB a few
years ago.

I believe most of the frequency bands where low-power, unlicensed use is
allowed by the FCC are subject to the same thing. Most carry an FCC required
disclaimer that they are not allowed to interfere with licensed use and must
accept interference from licensed use.

With more and more HA applications using RF in some manner, it will likely
be an ongoing issue, especially for all-RF systems like RadioRA, Z-Wave,
ZigBee, etc. It's one more reason why I think a reliable PLC system (e.g.
HomePlugCC) will eventually be the preferred retrofit solution.

And, those who import X-10 gear from the USA to save money should be aware
that the French military uses the same RF frequencies that N. American X-10
gear uses.
