Thats really cool Noble. I'm a tech novice here, but I have always wanted to make my Racal into a headset for my phone.
Does the talkabout 250 connector have anything in common with a standard 3.5mm jack that most cell phones use? (Sorry if that is a newb question, but I have not yet sliced any open to check)
Most cell phones use a TRRS (Tip, Ring, Ring, Shield) connector. yes you can adapt you just have to figure out the wiring of the pins.
I will do a hand drawn sketch once I get my hacking piece done. I am hoping to use some scraps from dad's garage to make a fascimile unit to look fairly close to the movie piece.
Our problem is that once something is about 30 years old, well, good luck finding parts. We kept running into that on our old 873 with a perkins 163 made by isuzu in japan for perkins of england for their order for bobcat in the united states. Same with the Case 850 diesel we had that had a cummins engine in it and no documentation or locatable serial number, ha ha.
In light of that I am more willing to use a mainstream unit still in production and easily sourcable to accomplish the same task.
