Still amazed at WSRO's Digital quality!

[Dave Doherty]

Although I am not conversant in Italian, I am subscribed to the Italian
Broadcast Engineering group on FB. They seem to be shutting down analog FM
in favor of DAB, and the engineers have posted dozens of photos of analog FM
sites that are now defunct.

Of course, US broadcasters would have been strongly opposed to the adoption
of any digital system that did not preserve the inequality of signals and
service areas, so the FCC never pursued such a thing, even when there would
have been plenty of VHF spectrum available to make it practical.  Canada
used the Eureka 147 DAB system for a while, in a less suitable frequency
band, and had very limited uptake on the part of both consumers and
broadcasters.  Meanwhile, a number of European countries have entirely shut
down mediumwave broadcasting and have or are in the process of doing
likewise for analog VHF FM.
