Biophone

The Biophone is a combination voice and telemetry radio communications system used in the 1970s and 80s by paramedics to talk to the physicians supervising them from a hospital base station.

The unit had a connector for a vehicle-mounted antenna allowing better signal reception and transmission from the back of an ambulance.

The Biophone could have any 6 (the maximum that could fit in the PE radio) of the 10 UHF medical duplex channels in the 450-470 MHz range.

[citation needed] This Biophone radio can be seen throughout the 1970s TV series Emergency!, being used by the fictional Los Angeles County Fire Department paramedic characters John Gage (Randolph Mantooth) and Roy DeSoto (Kevin Tighe).

The actual Biophone 3502 radio used on the show was donated to the Smithsonian's National Museum of American History.
