[Repeater-Builder] motorola repeater cable problem
I have two Motorola sm50 mobiles using a repeater cable that goes between the two at the option plug in the back. I have tried every configuration two get this to work with no results. Before I condem the cable I got off ebay does anyone know of any mods or settings that need to be done to get this simplex repeater up and running. I have confirmed the radio operation itself and they are good to go.

I've been in contact with a half-dozen folks via private email over the last few months and EVERY single one has been because COR was on the wrong pin. COR can be on any one pin of these: 4, 8, 12 or 14. See the tables on this web page: http://www.repeater-builder.com/maxtrac/maxtrac-option-plug.html Mike WA6ILQ

Dan, From your message I am guessing that you are trying to set up a crossband repeater from VHF to UHF. Otherwise you will need to explain 2 mobiles and a simplex repeater. The rear 16 pin connectors have some pins that are fixed in function (mic audio, PTT, Gnd) and some that are assigned via software (type of audio output, indication of valid PL/DPL/carrier detection). The switching functions must be configured to be active atthe proper level (High or Low). Both radios will need to be properly configured. The configuration of the cable must be bi-directional; it must pass the COS, PTT, and audio signals in both directions, GND is comman between both units. Without the proper equipment and software to program the radios and documentation of the radio and the cable it's going to be rather hard to get things properly set up.

Re: [Repeater-Builder] motorola repeater cable problem
I hooked a pair of GM-300s together for a friend who bought a cable off the internet, and it worked just fine. All I had to do was set the level for deviation with the pot mounted on the board that also mounts the radio connector. The cable he got would cross-band repeat, meaning that it would transmit and receive on both radios, taking audio and key from one radio to key the other. All I had to do was have one radio programmed for the repeater input frequency and leave off the transmit frequency. The other radio was programmed for both transmit and receive. The receive frequency for the second radio was programmed to an unused frequency. The first radio gives a couple of beeps when you turn it on indicating an error in the programming (probably since the transmit frequency is not properly programmed). The repeater functions just fine this way. The cable does not provide for any squelch tail delay, but other than that - it sounds like a normal repeater. 73 - Jim W5ZIT --- On Tue, 1/6/09, dan d dwd71...@yahoo.com wrote: From: dan d dwd71...@yahoo.com Subject: [Repeater-Builder] motorola repeater cable problem To: Repeater-Builder@yahoogroups.com Date: Tuesday, January 6, 2009, 8:30 AM I have two Motorola sm50 mobiles using a repeater cable that goes between the two at the option plug in the back.
