Mark, With the capability to have 16 users, I am guessing that it is more likely to be a community repeater station than a PURC station. Of course, there may be components that are common to both.
Since you already have the manuals you need for a basic Micor repeater, you might consider swapping the TRN6421A backplane for a "standard" TLN5644A backplane. That way, you can use readily-available modules, and not worry about finding new manuals. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of n9wys Sent: Sunday, July 27, 2008 4:56 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] UHF MICOR Unified Chassis I looked at 7 of the 14 chassis I have; the ones I looked at were *all* TRN6421 - including those with what appeared to be the Zetron interface wiring.

Most of the time that I have seen the TRN prefix, it usually has been tied to the PURC series of radios. Are all of your backplane boards that you have, this same model number? On the backplane board what are the cards slots labeled as? Knowing this information may help identify what the original station service type was.
