However, it doesn’t make sense as the receiver reports a strong signal and doesn’t show signs of loss of signal on the front alarm panel. The GPS antenna is designed with high RF immunity and is at a site with little activity.</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>Kindest Regards,</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>Kevin Babich | N9IAA</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>Valparaiso, IN 46383</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>From:</span></b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'> App_rpt-users <<a href="mailto:app_rpt-users-bounces@lists.allstarlink.org" target="_blank">app_rpt-users-bounces@lists.allstarlink.org</a>> <b>On Behalf Of </b>Hayden Honeywood<br><b>Sent:</b> Thursday, May 31, 2018 5:56 PM</span><o:p></o:p></p><div><div><p class=MsoNormal><br><b>To:</b> <a href="mailto:app_rpt-users@lists.allstarlink.org" target="_blank">app_rpt-users@lists.allstarlink.org</a><br><b>Subject:</b> Re: [App_rpt-users] RTCM [RX Packet Out of Bounds] ***Updated***<o:p></o:p></p></div></div><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><div><div><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Is the time in UTC?

Are all RTCM TX buffers set to the same value? Yes, 480. These values were based upon the math Jim provided, which is a function of maximum latencies on the network. We rarely have greater than 1ms to any host on the network.<br><br><br><br>Are all the GPS's in a location where they cannot be swamped with RF? Yes, and they utilize PCTEL antennas with filtering for use in RF dense environments.<br><br><br><br>Some users have had success with a dedicated RTCM as the master timing source (with no radio connected).

I can infer its meaning, but, one can’t be certain. Any thoughts why the system time is always so far off? It has always been, since I began experimenting with the RTCM in 2012.
