<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Thank you 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.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Is there an 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.<o:p></o:p></span></font></p>

Seriously? (I know I'm working on cup #1 and it's not quite 6am... I had
to read this a couple of times to 'really' see this question and it's just as
silly, every time!)<o:p></o:p></span></font></p>

synchronizing transmitters for simulcast, then that is done with an external
