Funny that you say that, because they use an average of about 46 kbps,
which is actually over the average used for HD radio. That this is not
adequate to match FM is what we are trying to tell you for some time now.

Where did you get the idea that HD averages less than 46 kbps? If it's
HD1 only then it's 96 kbps. If there are sub-channels they divide that
up, but unless they have more than one sub-channel, the average could
not be less than 48 kbps.

Most stations use subchannels. There are very few stations using more
than 48 kbps. The difference between 46 and 48 kbps or something like
that will be hard to notice.
Of course the smart thing to do would be to use the digital for a second
service *only* and leave the first one on FM (for now). For instance an
owner of an AM and an FM station might simulcast the AM on the HD at 96
kbps to lure the audience over. The big saving would come when the AM
can be switched off. The FM would of course benefit when the FM goes as
well and the bandwidth goes up. A third station could be added then.


Also remember that once analog is turned off there will be 300 kb/s to
be divided up among the channels.

Of course, but that is of no use at all for now and many years to come.

In any case, there's no contest between the quality of audio on
satellite radio and HD Radio, HD Radio is far better.

Bitrates are similar, sound is similar. I tried both. There are a few
positive exceptions though, indeed some of the ones transmitting just
one service.
