Hi all, I posted this problem many months ago and I came to the conclusion at that time that it was my 1PPS signal from the GPS into the RTCM that was the problem. I have changed hardware now to fix that and I still have the problem so I am suspecting a config issue and hope someone will have an idea. This is on a stock DIAL box. RTCM is setup and working great as a standard node. Everything is working great on the repeater as long as RTCM is in non-voter mode. I have the chan_voter module loading in modules.conf. Here is my voter.conf: [general] port = 667 buflen = 200 password = blah [1115] Horsetooth = blah,transmit plfilter = y txtoctype = none I am happy to share any other config if requested. In the RTCM menus, I have a static IP, I have the voter server IP, all the approriate IP fields filled out. As mentioned, the RTCM works fine with the asterisk server when it's in non-voter mode. Here's the way I am testing: Verify RTCM menu item 10 is set to (2) None. Boot server, then boot RTCM. RTCM console says: GPS Receiver Active, waiting for aquisition GPS signal acquired, number of satellites in view = 9 04/05/2016 17:58:17.560 Time now syncronized to GPS 04/05/2016 18:13:18.580 Host Connection established (Pri) (10.16.1.240) I have a very nice, clean, 5Volt 1PPS signal going to pin 7 on the DB15. Verfied with o-scope. as soon as I change menu item 10 on the RTCM to either a (1) or a (0) instead of (2), I *instantly* get this on the RTCM console: 04/05/2016 18:44:13.660 Lost GPS Time synchronization 04/05/2016 18:44:13.660 Host Connection Lost (Pri) (10.16.1.240) and it sits there forever and never re-establishes connection to the host. Here is a snippet of the GPS output: $PFEC,GPtps,160405181603,1,0,1,150701000000,00,17,160405165607,1891,238580 $GPGGA,181603,4020.9810,N,10506.4515,W,0,07,00.00,001566.7,M,-020.0,M,, $GPGSV,2,1,08,03,53,215,46,07,09,253,37,09,28,305,39,16,63,126,43 $GPGSV,2,2,08,22,26,178,44,23,60,316,43,26,52,066,41,31,17,061,34 $GPRMC,181603,V,4020.9810,N,10506.4515,W,,,050416,008.9,E,N*1A $PFEC,GPtps,160405181603,3,0,1,150701000000,00,17,160405165607,1891,238580 $GPGGA,181604,4020.9810,N,10506.4515,W,0,03,00.00,001566.7,M,-020.0,M,, $GPRMC,181604,V,4020.9810,N,10506.4515,W,,,050416,008.9,E,N*1D $PFEC,GPtps,160405181604,3,0,1,150701000000,00,17,160405165607,1891,238581 $GPGGA,181605,4020.9812,N,10506.4495,W,1,07,01.73,001573.3,M,-020.0,M,, $GPRMC,181605,A,4020.9812,N,10506.4495,W,,,050416,008.9,E,A*0F $PFEC,GPtps,160405181605,3,0,1,150701000000,00,17,160405165607,1891,238582 $GPGGA,181606,4020.9812,N,10506.4494,W,1,07,01.73,001573.2,M,-020.0,M,, $GPRMC,181606,A,4020.9812,N,10506.4494,W,000.0,283.2,050416,008.9,E,A*06 I am just not sure where to go from here. I can't seem to find anyone that's had any problem like this or what might be causing it. I have tried 5 different RTCMs and 5 different GPSs from 3 different manufacturers. Any suggestions on what I might be missing? Many thanks for any help anyone can offer! James KI0KN
