For those of us who use Trimble GPS units be aware that a bug has cropped up with these units impacting RTCM voting/simulcast systems. RTCMs without GPS timing are not impacted. In voting and/or simulcast applications the date and time of all clients must be an exact match with the server's RTCM in order to provide seamless audio switching and launching. The Trimble bug has reverted it's date to 1997. This causes Trimble timed RTCM's to not send or receive with non-Trimble timed RTCMs. If you have an all Trimble system, no Trimbles or no GPS’ you're good. Only mixed systems will experience the problem. See for more: https://www.m1dst.co.uk/2017/08/trimble-thunderbolt-week-rollover-fail/ Don’t know what the fix is yet. We’re looking for options. -- -- Tim
