摘要： Time referenced RF signals are periodically received and processed for updating a microprocessor-controlled clock. The clock automatically scans several frequencies at which the coded RF timing signals are transmitted, selecting the strongest received signal for synchronization therewith and causes a capture LED to be illuminated upon detection of a sufficiently strong signal at the beginning of a minute tone at one of the received frequencies. The microprocessor periodically determines the timing difference between an internal timer and the received RF timing signals. A time difference correction is provided to a digital-to-analog converter which provides an appropriate voltage to a varactor diode in a crystal oscillator circuit for adjusting the microprocessor's operating frequency until it can no longer resolve a difference between the received RF timing signals and its internal timer. This permits highly accurate clock operation in between the periodic reference time updates and eliminates cumulative time error. Manual switches are provided for correcting for received signal propagation delay and for selecting the appropriate time zone as well as for allowing for daylight saving time and UTC.sub.1 correction. In addition, the microprocessor-controlled crystal oscillator ensures accurate time-keeping when the transmitted RF timing signals are too weak for clear reception.

摘要： A scanning radio and method using a receiver, a channel memory and a display in conjunction with a frequency and linked descriptor database. The frequency and linked descriptor database is queried using a geographic reference to produce a list of local radio channels that includes a list of frequencies with linked descriptors. The list of radio channels is transferred into the channel memory of the scanner, and the receiver is sequentially tuned to the listed frequencies recalled from the list of radio channels while the corresponding linked descriptors are simultaneously displayed.
