A '''Plectron''' is a specialized [[VHF]]/[[UHF]] single-channel, emergency alerting [[radio receiver]], used to activate emergency response personnel, and disaster warning systems. Manufactured from the late 1950s, through the late 1990s, by the now defunct '''Plectron Corporation''' in [[Overton, Nebraska]], hundreds of thousands of these radios were placed in homes of first responders across all of North America. This included [[ambulance]] crews, full-time and volunteer [[firefighters]], off-duty specialized [[police]] response teams, [[Civil Defense]] members, and [[search and rescue]] teams.

A Plectron's main feature (distinguishing it from a regular [[squelch]]ed radio) was its selective de-squelching. It would only sound when a correct pair of tones were broadcast - allowing many agencies (with different tones) to share the same frequency. Some Plectron Models had a set of "Built-in Re-chargeable Batteries", making the Plectron Portable. The [[Motorola MINITOR pager]] also uses this function and has largely replaced the Plectron.
