ABSTRACT:
To program a scanning receiver for selected priority, a counter in the scanning control circuit is manually stepped to the channel to be selected for priority and that channel is indicated in a memory by depressing a program switch in the program mode while the memory is being addressed by the scanning circuitry. When the scanning circuit thereafter begins scanning, it returns to the established channel. A special weather and alert channel may be energized on the frequency set aside for weather warnings and emergencies by depressing a switch. This channel is continually sampled when the switch is in the energized position so that all such warning signals will be received.
