RAY JEFFERSON 7878 VHF FM 55 Channel 25 Watt Marine Radio

Circa 1988

A fixed-mount communication transceiver designed for watercraft.

Use Case:

This radio provides essential voice communication for marine vessels, operating on VHF (Very High Frequency) marine band channels.

• Communication: It allows boat operators to communicate with other nearby boats, marinas, bridges, and the United States Coast Guard or other rescue authorities.

• Emergency Channel: The dedicated "PRI" (Priority) button likely switches immediately to Channel 16, the international distress and calling frequency.

• Weather Monitoring: The "WX" (Weather) button provides access to NOAA weather channels to receive severe weather alerts and forecasts.

• Scanning: The "SCAN" function allows the user to monitor multiple channels sequentially, while "DUAL" allows monitoring two channels simultaneously, typically Channel 16 and a working channel.

• Power: The unit operates at 25 watts, a standard power output for VHF marine radios, with a low power setting available for short-range communication in harbors or marinas to avoid interference. 

Historical Significance:

Devices like the Ray Jefferson 7878M represents a period of significant standardization and technological adoption in marine safety and communication.

• VHF Dominance: The widespread adoption of affordable, reliable VHF/FM radios like this one largely replaced older, less reliable AM radiotelephones and direction finding (RDF) radios.

• Safety Net: The consistent monitoring of Channel 16 became a crucial safety net for mariners before the ubiquity of personal satellite communication devices or GPS-enabled distress beacons.

• Design: The radio's durable, plastic construction and compact size made it suitable for the harsh marine environment and easy to mount in small boat cockpits.

Accessories Available Separately;

• Hand Mics.
