I want to make an amplified PTT so I can use it with one of my boutique radios for which premade PTT adapters do not exist. I have several PTT both oem 3M (peltor) as well as those made by Disco32.
I have purchased a speaker mic for the radio which I intend to cut off and use as a pre-wired connector. I have purchased a nexus U94 part and am just looking for some assistance with the amplifier circuit needed to make this all work. Does anyone know where I can find an electronic diagram for one? Bonus if someone knows how to make it all fit in a u94 chassis.
Brother is electronics guru so he can help build it, but I figured it would be easier to get some info if anyone else has done this before.
Headset is peltor comtac 3.
Thanks for your assistance.
