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.

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.
