ComTech's channel marker circuit board is an accessory item for Motorola's CentraCom II and Gold Elite consoles used with trunked radio systems. ComTech's channel marker is designed to provide a short beep over radio channels notifying listeners a "special event" is in progress and radio transmissions on the channel should be kept to a minimum. Special events would involve officer and/ or public safety. The beep tone is timed and adjustable to typically less than 1 second in duration and spaced up to 10 to 20 seconds between beeps.
