Could be.That's what is happening. Sats in view never drops below 9 or 10, but the sats in use goes to 3, and then we get a sync event.
The view/use qtys don't really change after the power cycle, but the sync events stop for at least 3 weeks.
Smells like a memory leak to me.

Oh yeah, that one. Didn't realize it was still occurring.Let me pull my notes on that. I don't remember if the injector was seeing the events as well. My vague recollection is the sats in view number was dropping, and the GPS was coming out of lock. I'm still finding it odd that a reboot fixes this for some time. I'll ask my GPS vendor if they have any ideas. Wild speculation: maybe they do a power on calibration of some sort which drifts over time and needs to be re-performed every once in a while.-forrestOn Thu, Feb 18, 2016 at 12:23 AM, Bill Prince <[email protected] <mailto:[email protected]>> wrote:Yup. It's a SiteMonitor II, plus a sync injector plus a sync pipe. It's not in the best location. It's on the 11th floor of a 13 story building, and is blocked from seeing ~~ 190° of the sky. It's exposure is generally south. From the time we installed it, it would occasionally get sync events. We figured it was probably the lack of a good sky view, but decided to replace the sync pipe anyway, just in case the one we had was particularly sensitive. Lo and behold, the new sync pipe did not get any sync events for ~~ 3 weeks. We thought we had fixed it. Then it started behaving the same way as the old one. On a hunch, at 0-dark:30 one night, I power cycled the sync pipe and sync injector. By golly, the problem cured itself for another 3 weeks. Hmmm. maybe I got something. So the next time it got a couple of sync events in one day, I power cycled it again. Rinse. Repeat. bp <part15sbs{at}gmail{dot}com> On 2/17/2016 11:00 PM, Forrest Christian (List Account) wrote:On this site, I'd like to find out more about what the syncinjector is seeing ... is there a sitemonitor attached to it? I get random reports occasionally where there is 'something odd' happening. Where this is recurring, and there's a syncinjector attached, this seems to present an opportunity to look at this when it's misbehaving and figure out whether it's the syncpipe misbehaving or something else. Would I believe that the GPS receiver can get into a state where it isn't happy and needs a reboot? Definitely. But these tend to be really hard *especially* if you can't get instrumentation on the misbehaving device. If this is reoccuring, then we can possibly get a look at this.

We've found if we power cycle the sync injector and the sync pipe, the errors "go away" for a period of 3 - 6 weeks. So that is our solution for the time being. We set up an alert when we get sync errors. At which time we power cycle the sync injector/sync pipe during off-hours (~~ 2AM-3AM), and wait for another few weeks. bp <part15sbs{at}gmail{dot}com> On 2/16/2016 8:07 AM, Forrest Christian (List Account) wrote:The only issues I've heard like this are specifically related to mounting in a bad location, and then the problem seems to come and go just like you expect.The units don't really have firmware on the unit itself, only in the GPS module, and I can honestly say we've neverhad to update a module in the field. I don't even know how to make that happen at this point other than it can be done. The modules come from the factory with our preloaded firmware, which never changes unless we switch modules, which has happened once, the last time being at least a year ago. One caveat is that the newest syncboxes have been modified to work with the 450i. So the radio driving electronics areslightly different, even though the firmware is the same. This only is relevant to units shipped in the last month or so.If you can come up with the serial numbers of affected unitsthat might help in case something happened to a batch here (like some undetected bad modules from our supplier)The other thing to look at is if the status screen is really updating on the radios. If the gps module doesn't supply data, the screen stays the same.

However, several of the syncbox12's we have deployedseem to loose and acquire sync repeatedly until they are power cycled. This affects all the customers on the tower during that time. Is there a firmware version that fixes this? I'm not sure how to even update firmware on a syncbox? The Sync status tab always shows that the device is tracking 10 or so satellites but the device is not passing sync on. In some other installations we have out there they have never had any issues. It seems to be several that were deployed about the same time that are doing this but I cant swear to it. Forrest?? is there an easy fix to this or have you heard about this from anyone else?
