I agree it sounds like noise. Mikrotik has an SA as well but isn't supported on all cards.

Don't look at the noise floor. Get a UBNT in spectrum analyzer mode, and let it run for a little bit. I bet you find something bleeding over the frequency.

Replaced all the electronics at one end early this morning. No real change. Replace the cable and antenna at that end this afternoon. When we got there the link was running with RSSI of around 67/70 and CCQ in the 50's both ways. Aligned the antenna and I watch the stats for a while while the climber we getting the old antenna off of the tower. Signal strength went to around 57/65 and quality was running in the high 80s to mid 90s. Thought it was fixed. Climber finished attaching new cable to tower as he came down. When He got to the bottom I checked things again. Signals are 67/70 and CCQ is all over the place. I have seen the CCQ jump from 90 to 14 at least once this evening. It didn't drop the link at 14, rather it climbed back up to nearly 80 and then dropped. I am at a complete loss as to what is going on. Oh, the last time I looked, noise floor was around -100 so SNR is running 30 to 40.
