Wiring a 2 way radio headset to also record audio? Answered

I am a hang glider pilot and like to take videos during flights. I would like to add narration and the back and forth communication with my chase driver as part of that. I have a headset in my helmet that is wired to a ham radio for that communication. The jack to the helmet is a three conductor, 1/8" jack that goes to the earphones, microphone and a common ground. There is a push to talk switch that trips the radio to transmit which is between the helmet and the radio. What I would like to be able to do is put a jack/splitter inline with the existing jack to then go into the mic jack on a voice recorder to get three things; Radio audio (receive), Radio audio (transmit) and me just talking into the headset mic - Narration.Not sure how well I am explaining this and I could just experiment, but I am thinking it's not as simple as just wiring stuff together. I'm good with a soldering iron, but no EE by a long stretch.

Any thoughts?



Did you managed to get this done?

If NO, let me know. I am not sure if this thread is closed as I am new and happened to stumble upon this.


I have a cheap MP3 player that will record audio - I guess you could take the audio out and wire to the mike connection on such a device.

Depending a LOT on what equipment you have will decide how and if it works.

You may have to buy or experiment.

I found a website (cobham.com) that makes 2 way radios with the ability to record audio on them... I know that doesn't answer your question, but honestly I have no idea how you'd go about wiring something that you described.
