I have used a pair of DR radios in a cross band repeater and all the signals you will need are present on the DB9 connector. Use the 1200 Baud packet connections and you will be all set.
Realize that the COS output is an open collector that keys to ground, so you will have to use a pull up resistor to interface the RLC-4. The radios are configured so that if you wanted, you can directly connect the COS to the PTT of the other radio and connect the audio out to the audio in of the other radio and they will repeat. 73 - Jim W5ZIT --- On Sat, 1/30/10, ve6cpu <[email protected]> wrote: From: ve6cpu <[email protected]> Subject: [Repeater-Builder] Alinco DR-135 and RLC-4 To: [email protected] Date: Saturday, January 30, 2010, 12:10 AM Just a warning up front. I'm really new to the RLC-4. I've done 1200bps packet on a bunch of different radios. I've got my hands on a RLC-4 that I'm thinking of hooking up to a pair of dr-135 radios. Looking at the docs on the both the controller and the radio it seems I could use the 9 pin din on the back of the alinco to run audio and COS to and from the controller. Just wondering if anyone out there has tried this before? Is this something that can be done easily or do I have to get in to the radio and pull the audio and COS from somewhere else? I don't want to hurt either piece of equipment just trying things out. Thanks for any help you can provide. Stephen VE6CPU
