Isn't the estimate that something like 90% of all wireless mics are being used
by folks who technically never had the authorization to use the spectrum
(...that is used...) is the first place? Something like how only radio and TV
stations had the authority to use the standard wireless mic frequencies, but
these days anyone doing professional sound for theater, sporting events, etc.
is also using those same frequencies?


The FCC and the TV broadcasters looked the other way because there is no
evidence that such activity has ever caused any interference. I can get
6 microphones to work in an occupied analog TV channel and neither
notices the other.

The TV Band Devices the FCC has recently begun the process of
authorizing are way more damaging than a 50 mW 65 kHz deviation FM signal.

Luckily, these devices will not be allowed anywhere near where I work.
The FCC has banned them from the 13 biggest cities, and from within a
kilometer of a venue or stadium using wireless microphones. The
proposed rules do not require a Part 74 license for these protections.
