Dave, I've done a number of radios for making links. Usually commercial rigs bring out COS on a connector for they are often used in other applications such as remoted bases, etc. Having the docs is a must.
On Ham rigs COS is very seldom brought out. I've dug inside to find. It is there with any rig that has a squelch and is most often the audio on/off switch of the squelch circuit. I find a scope is most helpful with this. The point is it is there, but sometimes one has to dig for it. Sorry I cannot help with docs for the Relm rigs. 73, ron, n9ee/r >From: dakaratcaptivereefing <[EMAIL PROTECTED]> >Date: 2008/07/01 Tue PM 01:42:03 EDT >To: [email protected] >Subject: [Repeater-Builder] RELM SMUxx Link Radio? > >I've recently been tasked to link a couple of VHF repeaters with a UHF >link.. not too difficult, however the link radio's provided are Relm >SMUxxxx's, they are all programmed and ready to go. > >I'm just having trouble finding any good docs on locations to tap for >Rcv/Tx audio and maybe COS in these radios. > >On the plus side, I've bought an extra controller for myself and have >an extra mobile rig of the same model to experiment with before >tackling the repeaters... might as well make a mobile remote base for >my RV to play with while out fishing etc... > >Can anyone recommend a good starting point or some docs?
