Gervais, take a look at the link below for an interface to EchoLink for one of the PSE-508 controllers.
http://www.pionsimon.com/w5zit.htm My original interface used the stock GE Repeater Audio and Repeater Control cards, and I found that the PSE-508 could be modified the same way. But you can see where the signals need to come from in the GE Repeater for an external link. Use the RUS signal through an inverter to key your PTT on the link radio, and connect the audio to your link radio in parallel with the repeater transmitter audio input. You will have to condition your CAS from the link radio to operate the PTT on the repeater while the audio from the link radio goes to the mic input screws as shown. The opto-isolators can be used for both purposes, one to key the repeater and the other to key the link radio. The circuit shown has some provisions to interface RS-232 signal lines which you will not need for a radio interface, so you will have to make some modifications. I think I ran off a schematic for a radio interface to the PSE-508 that I may be able to find and forward to you if you are interested. You are probably not using a PSE-508, but this may give you some ideas for your controller. 73 - Jim W5ZIT --- On Fri, 11/21/08, gervais fillion <[EMAIL PROTECTED]> wrote: From: gervais fillion <[EMAIL PROTECTED]> Subject: [Repeater-Builder] Master 2 vhf and a link radio Uhf,How??? To: [email protected] Date: Friday, November 21, 2008, 11:16 AM Hi i have my repeater that is master 2 base repeater,,the oven as called. i wonder what is the simplest way to connect an uhf radio,Ge phoenix on her?? i could use the screew on her back plate?? i need an uhf that would be use as a link radio,anyone that want to use the Vhf repeater could "enter" via the uhf link radio. can it be done in a simplest way. i dont need cw id since i already have one on the vhf side so it would tx on uhf too. can you help me ?? thanks all gervais ve2ckn le bic,quebec _,_._,___
