ABSTRACT:
A station selecting device which comprises: a plurality of variable resistors, grouped into several reception bands, the variable resistors in each group being connected in parallel; band selection switches for selectively supplying power to the variable resistors of the desired band; and channel selection switches for picking up the tuning voltage across the selected variable resistor, said each channel selection switch being connected to one of variable resistors of each band. Since each channel selection switch is connected to the variable resistor of each band, the number of the channel selection switches required are very few as compared with the conventional device, which in turn reduces the size of the device and makes the construction simple.
