Purchased my first DISCO 32 PTT back in 2022. I use it with a set of Liberators and my Yaesu VX-6R in an Ops-Core Ballistic helmet. Works perfectly! Purchased another Disco 32 PTT ,,,,, same part # to use with an Ops-Core AMP headset and my same Yaesu VX-6R radio,,,, I could rcv OK but could not emit ,,,,, messaged Disco and they got right on it ,,,,, they payed to have the new one sent back to them ,,,, they troubleshot the problem, and fixed it in a very short time ,,,,, and then sent it back ...
