U-94 push-to-talk for Icom handhelds using the standard Icom 2-pin accessory jack.
This is a mil-spec U-94/A for this radio jack. Select Dynamic or Electret at checkout to match the headset microphone — they are not interchangeable. Headset side is U-174; red-ring U-384 downleads take the TP-105 o-ring. If you need one PTT that auto-senses both mic types, that path is Constant Able.
U-174 Headset
Radio Interface: Icom 2-Screw (I3)
Connector: Icom 2-screw (screw-attached) accessory connector — not the older straight 2-pin I1 jack
Verify your radio connector visually before ordering. Headset side is standard NATO U-174/U (TP-101). U-384/U (TP-105 / red rings) needs the TP-105 O-Ring adapter.
