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.

Right. Me too.

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.

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 3rd 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?
