Conference Call Amplified Push-To-Talk

You’ve got a lot to say. Say it all loud and clear with the “Conference Call”, the only drop-in amplified PTT board that supports two dual push-to-talk capable radios, a feat no other PTT can claim.

The Conference Call is simple to install in any PTT that uses a Kenwood style plug. Some we've tested and found to work well are the EARMOR M51 Single PTT and EARMOR M56 Dual PTT, which have shielded cords and a large amount of internal space to work with.

Compatible with any single or dual PTT radio that accepts Kenwood style plugs, the Conference Call is fully functional with channels A and B on both the Baofeng UV-82HP and Wouxun KG-Q10H radios.

For only $9.99, this first batch of boards is an early test release. Get a discounted board, test it out, and let us know your thoughts. We’re especially excited to hear from testers who have DMR radios, but any feedback on performance and function is good feedback.

Key Features:

• Amplify the microphone on PELTOR™ ComTac™, Ops-Core AMP®, and other similar headsets to work with regular commercial radios.
• Supports two dual push-to-talk radios at once. That's right. Four total push-to-talk buttons at once. If you dare.
• Secondary radio mute button / volume adjustment capability. Teammates won't stop talking? Not any more with the ability to mute or control volume to your heart’s content.
• Fully shielded band pass RF cancellation means that the only thing being sent is your voice. Background noise from unwanted radio signals is shunted directly to ground through a multi-phase filtering system.
• Hear optional stereo audio when using a compatible headset and wiring setup.

Be advised: This board requires soldering to install. A soldering iron with temperature control and a conical/chisel tip less than 3mm wide is highly recommended. A multi-meter is also needed to check wires and pins on the radio connector and the headset socket.

Warranty: All Conference Call boards have a 90-day warranty in the case of manufacturing defects. Cooking a board due to improper soldering during end-user installation is not a defect in manufacturing.

Limited Liability Disclaimer: We’ve tested the design thoroughly for general function when wired correctly. Due to the necessary requirement of many variations of end end user installation, while we do provide a general guide to reference we are not liable for improperly installed boards damaging any equipment they are connected to.
