Push to Talk (PTT) with connections from Midland, Kenwood, Motorola, Yaesu and Topcom.
The PTT (Push To Talk) ensures that sound is transmitted over the channel only when the Talk button is pressed.
This prevents unnecessary (disturbing) sound from being sent over your channel and your team members from being bothered by it. PTT buttons come in different types, choose the one you find most practical. Pay attention to the connection in the walkie-talkie, these are brand bound.
