RDS Radio Data System
RDS transmits additional information in the FM 
frequency range. RDS stations have the follow-
ing properties:

transmit over a number of frequencies, 
there is an automatic switch to the fre-
quency with the best reception quality.
>If the reception conditions are good, the 
station names are shown on the Control 
Display. If the reception is weak or dis-
rupted, it can take some time before the 
station names appear.

Radio, please contact your nearest National 
Weather Service Office, or write to National
