I have an old STS AV7600VOR handheld radio, which is as good as new. STS are long out of business, I hear. I can find new batteries, no problem, but I can't seem to find an adapter that would let me plug my headset into the weird 6-pin plug it has. Anybody know where such a thing might be found? Searching the net, i am not the only one looking, but I found no answers.
I have a diagram that shows where the mic, speaker and PTT go in the plug, but that's it. It is not a Mini-DIN plug, nor a P2S, though it resembles those. I know nothing about electronics, but surely these plugs must still be around?

Will look around but looks like the the handheld mic cord from any mobile station.

Someone selling a radio. Might buy another one to get the adapter.

Thanks guys, but it is turning into a futile quest. I even talked to avionics shops who were baffled .

The plug is unlike anything out there, even though it may resemble others closely. Not visible btw, is the external thread around the jack, so the plug actually screws onto the jack as well.

Given the wiring diagram I have in the manual, I am thinking of simply getting a regular headset-handheld adapter, cutting off the exiting plugs and making up individual wires with pins which I'll push into the holes of the jack on the radio and then secure the whole mess permanently with epoxy and heat shrink tubing or something. It really is a shame to throw out this radio, which works great, has a brand new battery and even the VOR works pretty well.

Not knowing a damn thing about electronics - if you look at the diagram attached it gives locations for GRD, PTT, mic input and speaker out. Two pins are unused. Now if anyone can tell me how these would relate to the standard headset jacks, I'd be very happy. I could find out eventually, but sometimes it's just easier to ask someone who knows.

Before you give up, try a CB shop or an old amateur radio hand. It looks like some of the connecters on CB radios. It is not likely that it was special made for your radio, but was an off the shelf item for something. jrh

Agree, this plug was used for various electronics and not made only for this radio.

Look around, sure you will find it.

I have two of these old radios and have looked for the adapters myself with no luck. Please let us know if you find anything.
Thanks,
Jeff

I looked at the common CB 6-pin plugs - different configuration. Guess it's time for the soldering iron, epoxy and heatshrink tubing. Goes against my grain not to use a perfectly good radio...

Have you considered replacing the connector with a type that will fit in the hole on the radio and work with a plug that you have. I know this is obvious but why epoxy and make some thing permanant when it doesn't matter what the type plug as long as you have both the male and female plug with at least the number of termanals that is required to make it work.

Just my 2cents
