Re: [Repeater-Builder] Micor Repeater - ID?
Eric and Joe, Thank you for your replies. Assuming this repeater is in functioning (or near-functioning order) on its current frequency (464.050), is it possible to take it down to amateur frequencies? From what I read on the repeater-builder website, it seems like the procedure would be to (paraphrasingsimplifying here) replace a set of capacitors to retune the repeater and then send the channel elements to a crystal house to be re-crystalled/calibrated. Is this correct?

Good day, I just picked up what I believe is a Micor repeater at a Hamfest today for free. I'm told the repeater works, but I can't verify that. Here's what I know about it: Form Factor: Rack-Mounted Model Number: C64RCB-3105AY FCC Xmit Info: CC4224C FCC Rcvr Info: RC0080 Frequency: 464.050 MHz (I assume this is TX, but it doesn't say specifically on the label) Cards installed: 2x Four User Control Modules 1x Master Decoder 1x Squelch Gate 1x Station COntrol Module 1x Time Out Timer It has a Motorola power supply in the rack at the bottom. I didn't see any cans mounted in the rack, but I only found one N connector on the back (ublabeled, of course, but it looks like it comes out of a large silver box at the top of the rack with a heatsink on it. I can provide photos of the unit if needed. I'd like to convert this down to the 440 MHz amateur band if possible, for less than say, $1000 in new parts/repairs. Can anyone tell me, based on the information given, if this seems like a reasonable thing to do? If this is a boat anchor, I'm perfectly happy to get rid of it - but I figured, for free, what do I lose?

Actually, the C in RCB means continuous duty. If it were a T as in RTB it means intermittent duty. I found this information in almost every Motorola Micor manual I own. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of MCH Sent: Saturday, February 02, 2008 9:48 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Micor Repeater - ID?

Re: [Repeater-Builder] Micor Repeater - ID?
Mike, I think you need to know the following: The receiver is in the bottom of the unified chassis. It has a BNC connector, you should find that on the left hand side facing from the rear. The un-labled N (F) connector by the silver box is the transmitter output. Commercial repeaters are High In / Low Out, so should be 469.050 / 464.050. Likley there is also a PL or DPL element in both the Rx and Tx strips unless it is a CR backplane, then you will have the PL and/or DPL 4 user card and master decoder card. And, to answer your important questions, yes it should go down to the 440 ham band. Make sure it works on its present frequency and record how well, i.e., transmit power, recieve sense, etc... then follow the instructions on the repeater builder page for conversion. Good luck, thp Big Snip
