Nautel Ltd. is a Canadian manufacturer of AM and FM radio broadcast transmitters, navigational radio beacons, Differential Global Positioning System (DGPS) transmitters, medium frequency (MF) telegraph and NAVTEX transmitters, and high frequency (HF) amplifiers for dielectric heating applications. Nautel is best known as the first company to develop a commercially available fully solid state broadcast transmitter.

History

Nautel was founded in 1969 in the rural community of Hackett's Cove, Nova Scotia. Its primary operation was building and supplying solid state navigation beacons for the Canadian government. To better serve the US market, Nautel Maine Inc., a wholly owned subsidiary located in Bangor, Maine, was founded in 1974.[1]

Nautel delivered its first transmitter, a radio beacon for the Canadian government, in 1970. This was a fully solid state unit operating in the 190-535 kHz Aeronautical/Marine navigation band. These transmitters were the first ever commercially available solid state transmission devices, all transmitters up to this point having been of the tube variety. Because of the greater reliability and longevity of solid state transmitters many of these early models are still in use today.[2]

The introduction of 10 kW and 50 kW solid state AM transmitters from Nautel in 1982 and 1985 was another first for the broadcast industry.[2] The first 50 kW AM transmitter from Nautel was purchased by CBA (AM) in Moncton where it remained operational until April 8, 2008, when the station's AM signal was taken off the air.[3] Although commonplace today, solid state transmitter technology was non-existent before Nautel entered the market. More than 20 years after being introduced, many of Nautel's first generation of AM transmitters can still be found operational and on the air at transmitter sites around the world.

Nautel's introduction of solid state transmitter technology has had a large impact on the radio broadcast industry. As the benefits of solid state technology became clear, the industry began to shift away from the use of tube transmitters and began to adopt the more reliable and efficient solid state designs. By the early 1990s solid state transmitters were being widely used in radio broadcasting, while sales of vacuum tube transmitters began to decline. Since its inception in 1969 Nautel has focused solely on solid state broadcast technology with a lineup of 100% solid state radio transmitters at power levels ranging from 1 kW to over 1000 kW.
