Hey, I don’t know if this is truly the best subreddit to post this in, but it seemed the most related to my question.
My job utilizes digital and analog (both simultaneously) Motorola radios that function with an earpiece with separate microphone and audio jacks. They’re switching over to Zello, which is an app for the phone that has push to talk functionality. Zello can support buttons on earpieces that are connected via wire to the phone.
I’ve seen someone discuss that the way cell phones and two way radios run buttons/microphones are not the same, and that it can actually short the connection through ground to the button and microphone when connected to a phone with typical adaptors. Is there a way or an adaptor that would allow me to use the existing earpiece I have, while connecting it over aux (and then from aux to lightning) to a phone? And is there a way that preserves the push to talk function of the button that’s already a part of the earpiece?
In case there are differences between headsets, the ones we use are also Motorola. I’m attaching a photo of the radios we have and the earpiece.
