Realize that this board was really designed for the Micor Mobile, and a Station COS is generated a bit different. My suggestion is to do the following modification to your Station Audio and Squelch Board so the Micor delivers the Active Low squelch logic that the SingleM is looking for: <http://www.repeater-builder.com/rbtip/station-a-s.html> Even if all you wanted to do was the COS part of the mod (and not the muting mod) that will be fine. This will effectively give you the same squelch logic as a Micor Mobile, and the SingleM will operate correctly as designed. > COS Pot doesn't seem to make much difference where I set it. > That pot only controls the Control Receiver COS logic, not the main receiver port. >Well let me double check later this evening as I stared at the project so long >I was overlooking an obvious diode.

Please do the A&S mod above and drive the controller from pin 8 of the A&S board, and all will be fine. After you get it going, consider the following modification for the Unified Chassis: <http://www.repeater-builder.com/rbtip/stationmod.html> This conversion will even allow you to eliminate the FET you added for enabling the exciter channel element, if you do the mods to the Station Control Module as outlined, plus, have nice controls for desense testing.
