Abstract
A multiband radio receiver having an electronic preset tuning system is provided with a switch which is ganged with a preset switch in the electronic preset tuning system, so that an automatic frequency control is interrupted from a local oscillator in preset operation. During preset operation, no automatic frequency control is provided, as a result of which fine-tuning can be accomplished to memorize a digital signal representative of a completely tuned frequency in a read-write memory.
