Are these not USA channels?
If am wrong let me know and I will change them.
Yes, if your radio is type-approved for 15.407 with DFS. Otherwise only
the latter block, which can be type-approved under 15.247 and doesn't
use DFS. The first three blocks are UNII-2, which requires DFS. And of
course the power limit there is lower.
AFAIK no MikroTik radios can legally use the DFS frequencies. UBNT has
it approved on at least some models as of AirOS 5.5.2. I have however
seen "professional installers" put up MikroTik radios on, uh, unapproved
frequencies. I don't know if any UBNT radios block operation even if
they are up to rev. Ticking off "obey regulatory rules" on a v5.3 radio
certainly does narrow the frequency choices... anybody have an up-to-rev
one handy?

I'm going to agree with others...
Running outside legal limits doesn't look good to the FCC, and it
sounds like you are definitely running outside the limits since
you are whining about the ability to run your radios in a mode
which seems to have no use than to exceed the limits.
I will also add that if you're running all your radios hotter than
they should be that your nose floor problem is most likely self
inflicted. My experience over the years is that radios are
designed to run at a specific tx power and if you're exceeding it
you get a lot of out of channel bleed over. Even if the radios
don't do this you are introducing far more rf than is likely
needed causing an overall rising of the noise floor.
Please don't interpret everyone's ire incorrectly. We've just
all either dealt with an operator like you are now or have been an
operator like you are now. And right now we're trying to gain
credibility with the FCC which is hard to do when some operators
are flagrantly breaking the rules. Which makes us a bit grumpy.
I'm sure some of your neighbors out there would love to help you
better understand what you are doing to yourself and help you
improve your operations which will in turn improve your quality of
service. Heck, I'd drive over there for a weekend if my schedule
wasn't so packed.
In any case please ask for help in appropriate spots and let us
help you reap the rewards of a correctly and legally operating
network.

Recent events make me wonder if the FCC is trying to muscle
wisps out of these frequencies.
Since we are primarily Ubiquiti equipment I can only speak
from that platform.
First the latest firmware update removes compliance test which
for about 40% of our equipment deployed would render them
unusable since 5735 - 5840 runs at - 50dBm or higher noise
levels in our area,
Second is new product released only supports 5735 - 5840.
Seems like DFS is such a pain that manufacturers do not want
to mess with it.
Case in point the new NanoBeam M series only support 5725-5850
for USA.
Worldwide version which we are not allowed to buy or deploy
supports 5170-5875.
Seems the only alternative is to go with licensed P2MP which
makes more money for the FCC and drives the cost of wireless
internet up for both wisps and consumers.
