Abstract
A method is provided for selecting the frequencies of local oscillators and intermediate frequency converters of a receiver that selects the frequency for a first intermediate frequency converter, selects a frequency for a first local oscillator above the frequency of the first intermediate frequency converter to provide an overlapping harmonic first gap, and selects a frequency for a second local oscillator to provide a harmonic gap overlapping said first gap.
