DANIELS MODEL NUMBERS
Daniels Electronics Ltd. has manufactured radio systems for more
than 50 years. In the early years, Daniels manufactured AM and
SSB radiotelephones for the marine industry, and more recently,
the MT series of radios for mountain top repeaters and base station
applications.
MT-2
The MT-2 series of radio modules were originally manufactured in the
1980’s. This radio series was a crystal controlled analog radio system
capable of wideband (25 KHz) operation. Although systems are still in
operation throughout North America, this series of radio modules was
discontinued in the 1990’s and is no longer supported.
MT-3
The MT-3 series of radio modules were originally manufactured in
the early 1990’s. This radio series was available with both crystal
controlled and synthesized analog radio modules capable of wideband
(25 KHz) or narrowband (12.5 KHz) operation. The MT-3 radio series
is manufactured and sold for use throughout North America and the
world. The crystal products have been discontinued.
