Abstract
A radio selective calling receiver having at least two, i.e., a first and a second, local oscillators constituted by respective synthesizers. The oscillation frequencies of the local oscillator are controlled by the apparatus including a frequency calculator for executing frequency calculations according to the received call signal frequency and the oscillation frequencies of the first and second local oscillators so that harmonics of either one of the oscillation frequencies are not interference frequencies to the other oscillation frequency or the received signal frequency.
