There is clear value to the WISP industry if you register your base
station locations because -
1. There is a serious interference problem to TDWRs. The FAA
desperately wants to end this problem.
2. The FAA is pressuring the FCC to take action to end the problem.
3. The current "solution" is to ask WISPs to register their (base)
station locations in the database. Doing so gives the FCC a visible
sign to point to and to show the FAA that the problem is being
resolved because, in theory, having base stations (or both ends of a
point-to-point link) registered allows the FAA/FCC direction-finding
enforcement teams to quickly rule out registered WISPs as the source
of a problem, thus making their job of finding the actual
interference source that much quicker.
So even if you are staying clear of a TDWR frequency, registering
still helps to show the FAA and FCC that the WISP industry is
cooperating in the effort to end the TDWR interference problem.

Jack,
That is clear and I am practicing that. My concern was the
database.
Would it help to know I have nothing near those frequencies? Is
it only for people operating 30-100 Mhz within a TDWR? I guess I
just miss the point of the website. If operators stay away from
the "bad" frequencies what's the point of the website?

Josh,
The band is 5470 to 5725. This includes the 5600-5650 part
that the TDWRs use.
If you are within 30 km of a TDWR, you should stay at least
30 MHz away from it (below and above). For example, if the
TDWR is at 5610 then you should exclude 5580 to 5640. If you
are further away but within line-of-sight of the TDWR (like
on a high mountain) you should also stay 30 MHz away.
