There's some hiss in analog
but it goes away when the HD locks
I haven't heard any rumbling but I'm over a hundred miles away
down here on the border, and on the other side of the station from you
so it could be something up your way.
There are a few times when it seems I hear a transient echo but I think
that the audio version of temporary digital corruption (QSB related?)
like what would be seen as pixelation when it occurs on TV.

The hiss doesn't go away for people that don't have HD, oh, like
someone listening on a AR7030+. It isn't that the radio sidebands are
so wide that they are getting the HD noise (OK, signal) because you
can select a narrow filter on the 7030. Not all IBOC stations have
this problem, so it could be pilot error of the broadcast tech that
set it up.

Now the poor schmuck using a car radio, which doesn't have tight
filters, has to put up with the IBOC noise. So they brickwall the high
frequency content of the analog, add noise, then tell you it is for
you own good. This is so nasty, Dick Cheney must be involved.
