Abstract: In a radio or television receiver containing an automatic station finder with a digital counter, a clock generator, and a digital-to-analog converter forming the tuning voltage for the varactors, a recall memory consisting of two series-connected parallel memories is connected in parallel with the digital counter. At a stop signal from the automatic station finder the first parallel memory records the instantaneous count of the digital counter; at an automatic-station-finding start signal the second parallel memory, to which the parallel input of the digital counter is connected, records the contents of the first parallel memory.
