I have about a 7 mile hop with two 5GH dishes(32). I haven’t had issues with this link in sometime, but when the Freq Usage shows 0%- 1.3% on any of the channels I try, why would I see perfect CCQ (90-100%) on one side of the link and watch it fluctuate from 100% down to 12% and drop off? Is this a card going out and what else would I check to verify? Thanks for any help.
Hi,
It’s possible that you have interferences in this side of the link, near your radio. Did you see any new equipment there or near?
Well, I thought that could be it at first but a Frequency Scan shows empty on the channel it’s been on, & I tried 3 others with no serious difference. Wouldn’t I see something different on other channels? Thanks for the reply/help!
You can’t see this here. You can use the spectrum analyzer with a N card.
There are a lot of more channels you can’t see there, or people using 10Mhz channels, 40 MHz channels or non stardard channels.
With the spectrum analyzer you’ll see the interferences.
Try to use channels of 10 Mhz or 5 Mhz, and you’ll see it work better.
OK, I have a board on that tower with a N card in it, I will scan. Thanks for the insight. 
good luck!
