DISCO32 Constant Able PTT — Full ComTac Compatibility
The DISCO32 Constant Able series PTTs are fully compatible with PELTOR ComTac headsets. The ComTac’s standard NATO U-174 connector plugs directly into any Constant Able PTT — no adapters, no downleads. The Constant Able’s auto-switching circuit detects your headset’s dynamic microphone and adjusts impedance automatically — no manual configuration required.
This gives ComTac operators single-channel push-to-talk capability across a wide range of conventional and LMR radios: Motorola APX/XTS, Kenwood, Hytera, Harris/L3Harris, Icom, Baofeng, and more. If your radio isn’t covered by the FL4063 series, the Constant Able fills the gap.
