I don't see how it can signficantly block other stations. If the range
of it low as some have claimed then whats the difference from day?

As of yet the three AM ones I can get in HD haven't moved to hd at
night...now two of them are a bit out of range sometimes but one of
them is a 50kw so I guess they are deciding not to. In some reguards
it's a bit redundant because the power is such that probably a quarter
of the country could probably receive it

FM hd makes sense although I think AM definatly needs work. There's
things the IBOC can do to calm some people down...like what? how about
these for starters

1) giving a huge discount if not free transmitters for hd to college
radio, religious and non profit

2) We've seen similar content grouped with subchannels...why not the
opposite? Radio is known for some talk that definatly bends a bit to
the right...why not say attach air america as a subchannel on
something with rush?

3) sort of combining #2 and #1 how about subchannels that act like
the community band (88-90mhz) since that can get crowded and fm
transmitters sometimes override it.

4) Making sure that local channels retain local news and events rather
than having simply interruptions for other events
