Well, most of our issues seemed to just be flakey hardware... the first
link we put up was the very first batch (they were actually pre-orders...
made in California). One of them kept randomly rebooting, and we went
through trying everything we could come up with (cables, power supplies,
etc.) and eventually swapped sides to see if the problem followed the
radio, which it did - at which point we told them we wanted a new one, and
they were pretty quick about replacing it (and the RMA process was pretty
painless). Once we got that problem dealt with, that same link just refused
to run at full modulation (I don't remember exactly what it was doing, but
it was only able to handle around 500mbps of real traffic). I eventually
decided we should have a spare radio on the shelf anyway (since we had two
links up at that point) so I bought a new one and swapped out the last made
in California radio, and that link has actually been pretty stable now that
it has the new made in China radios on it... and for the most part it does
run at, or close to, full modulation (it does still drop down sometimes,
for no reason that's apparent to me, but it stays high enough that I don't
really care).

Now, our other link... why it won't run at full modulation is beyond me -
the signal is where it should be, and there's no reason I can see for it
(see attached screenshot)... and yes, it will randomly drop to lower
modulations with no change in signal level, or any other obvious reason...
it almost seems like it's picking up interference from 5ghz radios (whether
or not that actually is happening, or is even possible I have no idea). It
does consistently stay at high enough modulation to handle as much
throughput as it needs to, so I haven't really put a lot of effort into
trying to get it working better, but it just doesn't behave like I'd expect
a licensed link to.

I will say, I'm not complaining - the B11 is a good radio for what it is,
there isn't another 11ghz radio that can handle a full gig (yes, only one
direction at a time, but that's all I care about anyway) for anywhere near
the price, and their support has been pretty good, in my experience. Also,
a lot of my impressions came from dealing with odd problems on early
hardware, which is understandable, but I just don't see the B11 as being in
the same class as a normal licensed radio.
