Headset Compatibility
Compatible with tactical headsets using the standard U-174/U downlead.
Headset Impedance
This PTT is wired for dynamic (low impedance, ~150Ω) microphones — the standard for military headsets including Ops-Core AMP, 3M Peltor COMTAC, MSA Sordin, and OTTO NoizeBarrier. No radio menu changes required.
All PTTs below require a standard U-174/U (TP-101) downlead. If you have a U-384/U (TP-105) plug, you need our Adapter Pack.
