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 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 squelched 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. The Motorola MINITOR pager also used this function and have largely replaced the Plectron.
