Radio transmission system with compensated stability of the transmitting frequency and corresponding search of receiving frequency

摘要

The system has a radio transmitter with a transmitting control circuit, and a radio receiver with a receiving control circuit that is arranged to switch the receiver for receiving radiograms from the transmitter. The receiver has a timer with a time measuring device to determine transmitting time points, and a carrier frequency transmitter to provide a radio transmitting frequency. The receiver is arranged in a search run to implement an automatic radio receiving frequency search run with radio frequency search frequencies in the time intervals to determine the radio frequency of the receiver. An independent claim is also included for a radio system including a measuring device.
