A pager receiver includes an addressable data memory for storing sets of digital frequency data for application to a frequency synthesizer which responds to each set of frequency data to tune the pager receiver to a channel or frequency identified by the frequency data, and a process controller which controls both the storing in the memory of the frequency data identifying a plurality of channels or frequencies and the reading out of the frequency data one set at a time in sequence in searching for a paging signal being transmitted to the paging receiver. The pager receiver is operable in a preprogrammed mode in which frequency data which identifies a plurality of channels is supplied to the pager receiver from an external source with the pager receiver scanning only those channels for which frequency data is stored in the memory or in an all channel scanning mode in which the pager receiver rapidly scans all available pager channels or frequencies and stores in the memory frequency data which identifies only those channels for which acceptable signal level and system code is detected, the pager receiver then scanning only those channels for which frequency data is stored in memory.

A hunting arrow tracking system includes a tubular housing removably connectable to an arrow shaft and enclosing a battery-powered transmitter. The batteries are disposed in a container in the housing which is spring biased against a piezoceramic transducer which generates a trigger signal in response to longitudinal acceleration or deceleration of the arrow to set a latch for connecting the battery to the transmitter, thereby causing it to transmit a low duty cycle pulsed signal. The transmitter is connected to a strip antenna which extends the length of the arrow shaft and is adhesively secured to the outer surface thereof. A directional receiver receives the transmitted signal and indicates the direction from which it is being received. The latch can be reset by passing a magnet over the arrow to activate a reed switch.
