Jon Rorke for a well thought out reply. You hit the nail on the head and I
haven’t seen anything on this topic. That’s why I asked. I have a
Motorola MSF’s and a Motorola MSR that have a VCO input and I was curious
how to interface to it for simulcasting. I also have Motorola GPS receiver
modules that plug into the repeaters. I sincerely apologize if some find this
message thread as stupid, based on private emails, but not knowing where or who
to ask I thought that this was the correct mailing list.</span></font><o:p></o:p></p>

easier way that as a noob with Allstar I just don’t know about yet? If I
read you correctly any GPS that provides a 1pps output provides the VCO locking
in some form but is there a tutorial or a HOWTO that discusses this? I have a
TKR-850 that I want to use as well and I’m not aware of a VCO input. If
ya’ll could just point me in the right direction I’d be much
appreciative.</span></font><o:p></o:p></p>
