ABSTRACT:
A signal-seeking radio receiver is provided which utilizes a single crystal to establish a reference frequency and digital selection means coupled thereto, for selecting a plurality of predetermined and programmed frequencies from the plurality of frequencies in the high frequency (HF), the very high frequency (VHF) and the ultra high frequency (UHF) radio bands that are monitored for broadcast signals on those predetermined frequencies. All of these predetermined frequencies are scanned and, when one of said plurality of predetermined frequencies carries a broadcast signal thereon, the receiver is operable to broadcast that signal in its entirety. The receiver relies upon a singular antenna configuration for reception of all frequencies in the three bands. The absence of a signal on one of the predetermined frequencies allows the receiver and the digital selection circuits therein to rapidly and continually scan the predetermined frequencies in any or all of the three radio bands until one of the predetermined frequencies contains such a signal.
