I have one link which recently has started producing some weird numbers,
I think because of adjacent interference. The tower site is very RF busy, with FM/AM/Aeronautical/Everything sources… Another user has had
interference between 3pm and 5pm in the afternoons on their 5ghz link
but that effect doesnt show on ours..
The tower end looks like this

The other end is fine.

If the SNR is -3db which is correct based on a noise floor of -78db and a signal strength of -81db how come the links working at all let alone with
ccq’s of around 75%.. The Tx signal strength is also showing on the town
end maybe that attenna has shifted, but how come the link works ok..
