Are you seeing interference on the uplink, downlink or both?

The radio GUI does show they're getting timing via CMM. My concern is that the timing is wrong in some fashion and the radios simply accept it as good.

Forrest does warn that multiple sync sources can become an issue, which means you could possibly have a CMM and SyncInjector on the same tower showing they're both good in GUI but not working right.

My underlying issue is that two of the APs on the tower are interfering, so I'm eating another 25 MHz to solve the issue for the time being.

    Well, 1PPS Active value = 1 and Radio 1-4 Sync values are all 1..
    so yes, the radios should be receiving sync just fine.

    Do the radios say they're receiving sync via power port / CMM?

    Ok.  To me that says the device has GPS. Doesn't necessarily mean
    the pulses are getting to the radios and providing timing.

        You're tracking 12 out of 13 sats and very few ignored
        pulses. Looks fine to me.

            I know I have two APs that are having interference
issues. Changing the channel brings/fixes the problem. This site was put up a year ago and my problem didn't
            arrive until last week.

            I want to start by making sure my sync is proper and
            working. According to SNMP the radios are happy.  The
            GUI shows that CMM sync is good (it's configured for CMM3).

            I'm looking at the SiteMonitor and I'm not sure what all
            to look at, but here are some numbers:
            12Radio 1 Sync241100

            String values list out the satellites, I'm going to
            assume that's not relevant.  To my eyes that looks good,
            but I really don't know what I'm looking for in terms of
            potential problems. The stats are 317d old.
