Get this all the time in Utah and Nevada, but the DOD normally publishes a schedule and lets the FAA know.

I have two sites where only the ePMP 2000 GPS works (and works awesome). One is a FM tower with a licensed 900MHz feed about 30 ft away and the other is the power company with 900MHz omnis blasting away. I haven't tried the ePMP 2000 without the sector to enclose the GPS puck so I don't know if is the way they are shielding the puck or the cable.

A power-cycle will usually bring them right back. They just seem to get confused once in a while. I have one very problematic site. We've tried swapping pipes, cables, everything. It just goes stupid. At times even no visible sats. Power-cycle it and it will see 10+ visible, but still can't get lock. A couple more power-cycles will bring it back. And then it might go nuts again an hour or two later. Then it's perfectly happy for weeks. I don't get it. This is at a grain leg where we're in the process of moving between legs. The new leg is across the street about 500 feet. That one has a SyncInjector and pipe on the ground with metal all around and it works perfectly fine. Splain me that. In fact, I pretty much never have these issues with pipes attached to SyncInjectors. I have a site that has been running for 444 days and the 1PPS event counter on that injector is at... 1.

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.
