I doubt you need shielded cable for a couple of inches of adapter length.Some use Cat 5 stranded cable.

I've had issues in the past with stray rf. You don't have to use it. I've seen some opc-617 cables that are shielded, some aren't. A decent option is CAT 5W, the foil shield does pretty well. CAT 5 works as well (the one I pictured was CAT 5).

Ok I just found out that the folks I am building this repeater for now want a controller interfaced with it. So that changes what I need. Instead of the pigtail cable and the OPC-617 cables Preston Moore offered a Cat Interface cable that basically combines two OPC-617 cables into one that can plug into the controller albeit a CAT200B or since money is tight a ICS Basic Controller Kit. This combined cable is what I need. So is there a source out there that produces this cable other then Preston Moore. He is no longer building any cables. It is getting down to crunch time with this project. I really need to source these. So far I haven't been able to find anything compatible. Any help would be appreciated.

If you get a CAT controller, it comes with the DB-25 connector. There is no 'source' that I know of, for the controller interface cable. You need to make it yourself, and it is not all that hard to do. All you need is some shielded 4 conductor cable, and about an hour of time. COR, RX Audio, and Ground on the receive radio, and PTT, TX Audio, and Ground on the TX radio.

Your going to have to build it. What kind of control do they need?

Most radio shops I knew who built this kind of repeater either didn't put a controller on our just used something like an id-8 or nhrc micro.

Mostly they want it for a CWid. But also to be able to access it remotely. The radio can be programmed for hang time and TOT but since it is going in a remote location it needs to have a controller for setting up the ID and remote access.

If you are going to put this repeater in a remote location and use a controler of some type, then some things you need to know.

Use the OPC 617 and the a DB9 wired like the xcross over for the radio, on then wire to the controler just like a full xcross over cable.

Radio side of the OPC 617 pin out pin1-VCC pin 2-Dim pin 3-Horn pin 4-gnd pin 5-PAAF pin 6-gnd pin 7-DISC pin 8-gnd pin 9-in pin 10-gnd pin 11-PTT

Now DB 9 side pin 1-Dim or ign control in pin 2-Audio out pin 3-Det. AF out pin 4-tx audio in
pin 5-PTT in pin 6-Horn drive out (COR) pin 7-AF gnd pin 8-Det AF gnd pin 9-TX AF gnd.

This gives you the ablity to build a DB 9 to what ever is on the controler.

Also remember that you CAN NOT have any control of the radio remotely thru the controler unless you have some type of relay on the controler that can turn off power to the radio.

There NO WAY for external radio control.

You also will have a low level TX audio out that is set in the software, I set all of mine at 3 some times at 4, you will need to try yourself for quailty.

Hope this helps.

Some controllers actually won't key the transmit radio if the repeater is in "knock down". If it was just for ID, I'd say use an ID-8.
