[EAS] National Weather Service Message Flooding

[Clay Freinwald]

Agreed - 

RDS is find, as long as you are close to the stations transmitter, or are in
a strong  signal area.   RDS, like all FM Subcarriers, is a very problematic
means of delivery of text.    I wished I'd had the mind to take pictures of
screwed up RDS message - I recall one instance where a Christian format
stations RDS was reading something very pornographic as I drove thru a weak
signal area.    The HD variation of this is much better, at least you don't
get false and misleading messages.

R D S only works on R D S equipped radios. And it only works within a
certain distance from the transmitter since this subcarrier is not sent at
the same amplitude as the primary modulation of the fm transmission (the L+R
mono signal).

If I am driving from Saint Louis, MO after renting a car from the airport
listening to my favorite station I am loosing the RDS signal before I lose
the stereo signal from that station. Then I would lose Emergency Alerts if
we discontinued the very reliable existing EAS system which works in the
main audio.

Experience based on a trip from St. Louis, MO to Quincy, IL.
