[AFMUG] EPMP GPS Problems Increasing last week

[Nate Burke]

We've been running EPMP For a well over a year now.  I have not made any 
firmware changes in a while, everything is on 2.6.1, but last week I had 
2-3 sectors (not all sectors at the site) at 2 sites separated by 20+ 
miles that started having sync problems to the point where I had to set 
them to generate sync.  Is it just isolated to me, or is something going 
on with the GPS Sky thingies that is affecting EPMP?  All radios are 
using the included GPS Antennas, and have been installed for several 
months.  I'll see either all satellites disappear from the monitor->GPS 
page, or it will show satellites as visible but not tracked with an SNR 
of 0.  I have tried both Software reboot, as well as powercycle, and 
they're are still acting this way.

I've included the graphs for 3 sectors at the same site.  Blue is 
visible satellites, green is Tracked Satellites.  You can see the NW 
Sector has visible, but is losing tracking.  These were all working fine 
until last week.
