Abstract
A broadcast receiver includes an automatic search tuning arrangement, the tuning being automatically selected on operation of switches which correspond to a number of regions (A . . . F) and other switches which correspond to the chosen program (VF, P.sub.1, P.sub.2 or P.sub.3). These switches cause a control circuit (59) to address a gate circuit (95) to sequentially produce an output corresponding to a subarea of a region to be applied to an address memory (93) of a memory circuit (23). The address memory in turn causes a memory (33, 35, 37 or 39) corresponding to the selected program to produce codes stored therein which correspond to the transmission frequencies of that program and which are used to control the output frequency of a local oscillator (7) via a phase locked loop. The transmission chosen for reception is determined by a count of the number of receivable transmissions corresponding to tuning data from one and the same group.
