<p>45-MR-394 MULTIFREQUENCY SCANNING RECEIVER WITH PRIORITY FREQUENCY MONITORING A scanning receiver is provided with a pause detector which causes the receiver to tune to a priority channel during pauses in the transmission on a nonpriority channel. If a priority transmission is present, the receiver remains on the priority channel until the priority transmission ends. If no priority transmission is present, the receiver is tuned back to the former nonpriority channel.</p> |
