K7IZA was working on a board that does this. You might try contacting him thru his micro-node website.

This has been on my list of projects but aside from the RTCMs I don't have a source for the rest of the gear. What are you planning on using to convert the 10mhz ref signal to 14.4? I figured I'd be stuck buying Mastr III's or MTR2000's k0jsc On Wed, Jan 2, 2013 at 10:22 AM, Ron Simpson <n6gkj.cm98@yahoo.com> wrote: Hey guys, Happy New Year! Looking for ideas to cleanly phase lock a MAXTRAC. I have the boards, I have an idea on how I want to do it. Just would like input from those who already have done it. I looked online for some info but found nothing. I can break the ref osc tune line and take that signal out. I can pick off the 14.4 mhz and bring that out, but I want to do it cleanly, not a hatchet job. Anyone have pics? 73, Ron, N6GKJ Sent from Yahoo!
