What could cause all 6 APs to revert to their on board GPS even though they are all receiving sync from the CMM4 on the power port? The CMM4 shows it is receiving sync from the master GPS(See screen copies below) and the APs show they are receiving sync on the power port, but do not Xmt until they switch to the onboard GPS

This scenario is true with all APs powered up or just 1.
----We did have a previous problem- when more than one AP was powered up, the power port sync would go away on all of them. With just one powered, it would behave exactly as they all do now (Power Port=Receiving Sync and Sync Pulse Source=OnBoard GPS) Fearing RF interference, I grounded the copper sheath on all the CAT 5s to the power ports and now all APs receive sync on the power port at the same time.-----
We have 6 APs mounted at 295ft. A CMM4 at the base of the tower.
Superior Essex CAT5 (Copper Clad sheath)
Cable length is 304-306 feet between the CMM4 and APs
We also have a permanent Default Cable from the AP to the base of the tower (ends are cut and cleared)
Could this be RF interference? The tower we are on is basically 300 feet of Fire and EMS antennas (and our 6 PMP 450s at the top)

These are the stats for the AP on start up. Some APs sync to iGPS after only a minute, others will after a couple of hours. The CMM4 GPS reads good all the time.Sync Status

Today we plugged 2 of the APs into a UGPS via the timing port. Low and Behold! they immediately synced to the POWER port! This change is immediate, plug into UGPS--AP syncs to POWER port, unplug UGPS--AP is searching for sync.( eventually to the iGPS). The status of the POWER Port is always RECEIVING. At least one of the APs internal GPS is blind to the sky, so if it does not receive sync on the power or timing port, it never syncs.

Solution?!?- buy two more UGPS (or a sync splitter, or a sync pipe with 6 outputs) and plug into all 6 APs? This seems like an expensive fix to me. Why would providing sync on the timing port cause an AP to sync to the power port? I was hoping someone would tell me about the "rookie mistake" I am making. Or something I am overlooking.
Attached is the html contents that you had asked for. Please help me debug the issue.
The file I am sending you is for AP 4. Where the sync input is set to Auto Sync, but instead of getting its sync from the power port (which I want it to do), it's getting the sync from the onboard GPS.
In AP4 case it receive the synce from On-Board first and software uses it .Our software is designed such that whatever first GPS lock it receive whether Power or iGPS will use it.
Please send logs of AP1 , which is more concerning since it has sync on both iGPS and Power but still sync status shows searching.
For AP1, I want to let you know that I tried changing the parameter for AP Type from "Standard AP" to "Remote AP". When I did this, it immediately disabled the sync to the power port and synced to the on-board GPS.
My question is, how to I enable to the Power Port again? I tried switching the parameter back to "Standard AP" and a reboot, but it seems like that did nothing because it still shows that the sync to the power port is disabled.
Attached is the html file before I changed the parameter to remote AP, and another html file after I changed the parameter to remote AP.
