ABSTRACT:
In a digital tuning system for a radio receiver, which system includes a station memory having a plurality of memory locations for storing digit representations identifying respective broadcast frequencies to be received, a plurality of station selector elements each connected to be actuatable for addressing a respective memory location to cause the tuning system to tune the receiver to the station identified by the representations stored in the addressed memory location, a plurality of band selector elements each connected to be actuatable for causing the receiver to be tuned within a respective signal band, and components operable for continuously varying the receiving frequency to which the receiver is tuned, the station memory is provided with a plurality of additional memory locations and each band selector element is connected to address, upon being actuated, a respective additional memory location to cause the tuning system to tune the receiver to the station identified by representations stored in the addressed additional memory location, the additional memory locations not being addressable by the station selector elements.
