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