Actually, I am a programmer and a pretty good one. I am in favor of
anything that extends the life of AM radio or terrestrial radio in
general.
The consumer, too, should be in favor of this as commercial-based radio is
free, and every other option has ongoing delivery charges.



So, digital modulation is an attempt to extend the life of commericial
radio. Will digital modulation always remain free?
