Yah. Good point. We also have some AN-80s that are starting to get up
in age. But like you say, they are super stable, and they are doing the
job. They do provide more than the bandwidth we require of them, but
switching to something newer would conserve spectrum if we needed it.
Never thought they would be leaking at ~~ 700 MHz.

Not sure, the units are pretty old now and although super stable, well
out performed by more modern radios, so I will try the CPU frequency
thing for a bit, and worst case just swap out the gear.

Wow. I didn't think there was even an IF-anything inside an AN-80
(which we have installed, BTW). Wonder if this is a malfunction, or
maybe some other internal clock/oscillator (like maybe the CPU clock)?

The 711 carrier IS coming from the Redline AN-80 radio. This
device has a full metal case, and the whole works grounding wise,
but they have a very high gain panel antenna pointed at the unit
from across the street, so it shows up. Going to see if Redline
can give me a different build to resolve the issue, or just
replace it with a UBNT AC link.

You can request a build of the UBNT AirOS that changes the clock
rate. We've had to do that on towers near Verizon.

With the UBNT equipment, it's the clock rate of the CPU.

-87 sounds like a big deal to me if your RSSI comes in around
-100 or so.
That said, isn't the IF on Dragonwave in the 900 MHz band?�
I would not expect the Redline to have an IF at all.

Had an AT&T contractor show up at one of our datacenter

have a Dragonwave Compact 18Ghz system and Redline AN-80i
5Ghz system mounted on the building.

711Mhz doesn�t sound like an IF of either of these
systems to me, but I�ve got tickets in with the
equipment manuf. It looks like they are some 3^rd party
AT&T has sweeping buildings downtown. Anyone dealt with
these guys before? He told me he measured a -87 with his
directional antenna 10 feet away from the equipment and
acted like that was a really big deal, sounds like a
pretty low level to me honestly. Anyone know what the
legal limits for spurious emissions are in the 700-800Mhz
band?
