Abstract (en)

[origin: EP0762681A2] An EON list of transmission frequencies of radio transmitters and an AF list of alternative transmission frequencies is transmitted with the RDS data. Attempts are made to change to an alternative frequency when the field strength of the received signal falls below a minimum value. After several futile attempts to switch to an alternative frequency, the frequency range of signals indicated to have a minimum field strength is scanned. The frequency of these signals is compared with the frequencies stored in the EON list and when there is a coincidence the transmission frequency is adjusted.
