I have tried a couple of different circuits to fix it. I first built a circuit using 2 transistors and that worked sometimes. Then I built a 555 circuit and that worked better but still not perfect. I am still experimenting with both hardware and software to improve the results. The biggest problem is with power cycle restart, it is almost always 1 second off. Then I do a telnet session to reboot the voter and it sometimes syncs up with the correct time. Once I get it synced it stays synced for months, till the next power interruption reboot, then the voter will be 1 second off again. All of my other sites use the Garmin GPS and they almost always start up fine with both power up and software reboot.<o:p></o:p></p><div><p class=MsoNormal>I have verified that the GPS itself is always exactly accurate, it is just the Voter syncs one second off.<o:p></o:p></p></div><div><p class=MsoNormal>Chuck<o:p></o:p></p></div><div><p class=MsoNormal style='margin-bottom:12.0pt'><o:p> </o:p></p><div><p class=MsoNormal>On Wed, Nov 27, 2013 at 10:34 AM, Gary Herzog Gmail <<a href="mailto:kc5daq@gmail.com" target="_blank">kc5daq@gmail.com</a>> wrote:<o:p></o:p></p><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>We are trying to interface a Trimble-SVeeEight-Plus to the RTCM.
