I'm also interested in locking a transmitter frequency to stable reference. The ICOM FR-6000 repeater which I use has a TI LMX2352 PLL which relies on a 15.3 MHz Crystal Resonator, CR-826 type. It appears that I might be able to replace the crystal with a reflock board (Link below), with the reflock generating the 15.3 MHz. http://www.qsl.net/ct1dmk/reflock.html Here is an example of a ham reflock'ing a yaesu 817 all-mode radio to a 10 MHz reference input http://www.vk3hz.net/riglock/FT817_External_Reference.pdf The 10 MHz reference signal can be from a Rubidium Oscillator or from GPS Disciplined Oscillator, both of which are available from eBay. The Trimble Thunderbolt is a common GPSDO. Some good general info is on John's web site: http://www.ke5fx.com/tbolt.htm 73, Randy - VE3RWN / W3RWN On Wed, Jan 2, 2013 at 12:22 PM, 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?
