Military HMMWV circuit questions

Military HMMWV circuit questions

Military HMMWV circuit questions

I am a Sergeant heading over to Iraq. My XO wants me to create a circuit that enables us to hear our radio transmissions from our speaker box (24v, BN 123 connector - 6 pin), but when no transmissions are being heard, for us to listen to our music through our handheld player. I am trying to find a circuit diagram and/or parts list so I can create it. Any help would be great. Thanks ahead of time.

RE: Military HMMWV circuit questions

You might consider contacting Sigtronics.


They probably have what you need and would likely cut a deal for a soldier in need.

RE: Military HMMWV circuit questions

What's old is new again.

Way back during the Citizen's Band (CB) craze (19??), Radio Shack sold a gadget that performed exactly that function (allowing one to intelligently 'combine' the audio from a CB and a car stereo).

The interfaces are sufficiently different that, even if you happened to find one, you wouldn't be able to use it directly.

RE: Military HMMWV circuit questions

Standard audio mixers will do this, if you have the right adapters.  No need to build it if you can buy it cheaper.  Back in the day when Radio Shack actually sold electronic gadgets, this would be easy.  Now you might have to order it online.
