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.

OK. I don't have a big problem with folks using frequencies they're not
assigned when there isn't an interference issue, although I also don't have a
whole lot of sympathy for those same folks if one day they *are* interfered
with by assigned users.

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.

What are the power levels? Presumably the occupied spectrum is potentially
many tens of MHz?

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.

If these are consumer-type devices, realistically how will the FCC stop their
use in those 13 cities? It'll be like GMRS where technically everyone's
supposed to be licensed yet, in actuality, I imagine that well under 1% of the
actual users a If the consumer can buy a radio off-the-shop at Wal*Mart,
there'll use it wherever they want, regardless of what FCC rules say.
