Abstract
A radio which can operate in two separate frequency bands, with size, weight, and cost that is comparable with a conventional unit that can operate in only one frequency band. The radio includes two local oscillators which respectively produce signals at substantially the same frequencies for operation in both frequency bands. By appropriately choosing the frequency of the oscillators' signals, the radio can produce an intermediate signal which has the same frequency when the radio is operating in either band.
