Abstract
In order to program the output frequency of a synthesizer such as that of a two-way radio, first the reference oscillator is warped or tuned substantially to one limit of its tuning range. The 'N' divisor of the synthesizer dividor is then selected to produce a loop output close to the desired loop output frequency. The reference oscillator is then tuned to provide the desired loop output frequency.
