Tim,

You certainly have a lot more patience than I do!  If this is MICOR
equipment, both the PA and the bandpass filter require modification to
make them work on 2m.  Kuggie has instructions for modifying the
bandpass filter (on the Repeater-Builder Web Site), but the PA- that's
an awful lot of work.  I'm guessing that the PAs are TLD1694 models, the
"H" version, but what you need is the TLD1692 or "L" version.  Just
about every discrete component is different between the two versions. 
My hat's off to you if you have the time and energy to convert an H PA
to an L PA.  It's one thing to tweak a few components to get the PA to
work at all on 2m, but most of the components are optimized so that the
PA is efficient, stable, and spur-free.

Most MICOR stations need at least a Station Control module, an F1-PL
module, a Squelch Gate module, and a Timeout Timer module.  Depending
upon the capabilities of your external controller, you may be able to do
without all but the Station Control module.  You definitely should
obtain the two detailed service manuals for your stations before making
this decision.
