A car telephone described as having planned non-obsolescence is offered by the Harris Corporation,of Rochester, New York.
Harris' Alpha 2000 series car telephone will work in any channel spacing plan, including future channels as they are made available, according to Tim Vatcher, of marketing communications.
The radio has a 128 duplex-channel programming capacity, meaning non-obsolescence regardless of change in future regulations and allocations without major modification or major expense, he said.
Alpha's two synthesizers provide total flexibility in channel assignment without compromising performance, while the dual integrated synthesizers on two custom LSI chips replace dozens of discrete parts and circuits in other radio equipment, he said.
The LSI chips are designed and manufactured by Harris to their own standards and carry a 10-year warranty, the company notes.
Transmitter power output is 50 watts for VHF and 30 watts for UHF, providing greater talk-back range for rural applications and enhances urban operation where coverage can be artificially reduced by concrete canyons, Vatcher said.
Alpha's design is such that it can be taken apart and assembled with just a screwdriver, and there are no soldered connections, he said
