RDS/ RDBS

[John Bolduc]

My moms car has an radio in it the has RDS as a feature/option.

In playing around with it, I noticed that if you program an FM station
that has a clone, such as WOKQ 97.5/97.9/103.7, or the Shark 102.1/105.3,
that the radio will switch frequecies from one clone to another without
any human interaction. I'm guessing this is done based on signal quality??
(It reminds me of a public safety dispatch center which is tied in to
several receive sites, and a voter chooses the best signal to pass through
to the dispatcher.)
Can anyone enlighten me on what I am observing.  

I also noticed traffic messaging seems to be non-existant in New England.
I did get a message driving near Charlotte NC indicating it was a traffic
message, but in fact it was just a typical station promo message. Is the
traffic portion of RDS a subscription based service??
