Hello Mike,
I'm sure that was it's intended purpose but it is not responding to the
frequency that is noted on the top of the crystal can. We did not
follow up because it is to easy for me to run up and shut the thing down
if needed. I will have to do a little more study on the 70cm receiver.

Our Micro is on 2 meters and has a 70 cm receiver in the cabinet
who's frequency I don't know. Need to find that out!!
^ control receiver maybe??? just a thought...

Thanks Nate, I've put your email in the special folder on our
repeater.. I remember when I was with the Phone Co., we did just what
you are suggesting.. Wrote it all down, twice or three times, that was
before digital photos of course..

I think our Micor must have been properly converted because it
has been on the air for about 25 years according to the original owner
who I talk with 2 weeks ago. Our Micro is on 2 meters and has a 70 cm

The main reason for a possible change of equipment is the
possibility of some digital work later on.
Thanks for the pointers.

Side note for your project there Bob,
Just because it was "on-air" doesn't mean it performed well, or
even to spec.
If you have things like a UHF receiver in the cabinet that you
don't know what it is, now is the time to document, document,
document...
Later on, you'll certainly want to know things like, "Just where
is that wire from the controller hooked to", and digital photos,
drawings of all wiring, etc... are what you'll need. Attack the thing
with a label maker too, and label every cable interconnect and every
port they plug into. Take lots of pictures. Go nuts. Digital is
cheap.
Next, find someone with the right test gear and measure all the
basics as it's installed at your site. Receiver sensitivity off and on
the antenna system, transmitter power level, duplexer isolation,
feedline losses... whatever you can measure, and write it all down
somewhere -- start your "engineering book" for the repeater system, and
then require that if changes are made, the docs get updated.
You'll be happy you did later. And as friends say, if you haven't
measured -- you don't know where you're starting from...
