Jim, The TLN5970A Station Control Module (SCM) is used in Digital Voice Protection (DVP) stations, which have a TLN5979A backplane. The TLN4635B/C SCMs are used in almost all conventional Micor stations, which have a TLN5644A backplane. The two SCMs are not interchangeable!
The schematic of the TLN4635B SCM is in the Micor Control and Application Manual 6881025E60, which is now NLA. However, it has been scanned and will be posted on the RBTIP shortly. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of kh6...@netscape.net Sent: Sunday, April 18, 2010 10:59 PM To: Repeater-Builder@yahoogroups.com Cc: n3...@yahoo.com Subject: Re: [Repeater-Builder] Micor TLN 4635, info.wanted On Date: Sun, Apr 11, 2010 4:06 pm From: kh6...@netscape.net <mailto:kh6...@netscape.net> To: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder@yahoogroups.com> Thanks for your section in the Motorola Micor, Modification of the older Station Control Module TLN4635B, By Kevin Custer W3KKC.

[Ryan, you should be able to locate this. http://www.repeater-builder.com/micor/stationcontrol.html <http://www.repeater-builder.com/micor/stationcontrol.html> ] Any chance there is a schematic for the Station Control Module TLN4635B? Information on the jumpers? Are the Vhf & the Uhf Station Control Modules the same? Mine is on a Uhf Micor. The problem is constant transmit. In my Vhf & Uhf book, there is a section for a Stn ctrl module., TLN5970A. I await reply(s), thanks. 73's, Jim Kh6jkg. -----Original Message----- From: n3ssl <n3...@yahoo.com> To: Repeater-Builder@yahoogroups.com Sent: Sun, Apr 18, 2010 3:19 pm Subject: [Repeater-Builder] Micor ? Hi Group, I have a Vhf Micor unified station that was modfied prior to ownership. The Mods for the Station control module were performed as on the RB site. The problem I am having is there is no PTT on pin 5 of the back plane. Is there something i should check ? The Station control module is the TLN 4635 Ryan n3ssl
