Frequency synthesized scanner having conductive programming elements for channel selection |
| abstract |
A multi-band radio receiver is disclosed for automatically and sequentially tuning to a plurality of discreet, separate preselected frequencies. The receiver incorporates a phase locked loop frequency synthesizer which includes two separate voltage tuned oscillators alternately operative according to the band of operation of the receiver. Channels are selected by inserting metal combs having teeth removed to form a binary coded memory into corresponding sockets in the receiver. One comb is used for each of the channels to which the receiver can tune. By replacing a specific comb with an alternate comb, the channel to which the receiver tunes can be correspondingly changed. The combs are made of relatively brittle aluminum in order that they may be readily programmed to the appropriate binary coded decimal arrangement of pins. Programming is accomplished by the simple bending and breaking of the appropriate teeth on the comb to achieve the desired binary coded information to achieve tuning to the desired frequency. |
