Instead listeners must buy another radio, when their current radios
work.

Thats why it will take time for HD to gain traction.

No one expected people to throw out all their radio and buy new ones.

The new ones will start appearing in cars, etc...and will simply replace the
others.

This is why all the naysayers who want to proclaim it dead after 2 years are
wrong.

As was stated here...it brings added functionality to the old technologyu of
broadcasting....and operators like the extra streams.

It's not going anywhere.

So far IBOC stations are
simulcasts of existing stations, or mostly vanilla jockless jukeboxes.

Vanilla Jockless jukeboxes? Sounds just like satellite radio!
