I recorded Limbaugh yesterday, thinking to play it back later.

I forgot WTVN 610 Columbus OH was running IBOC, and so there's a
huge hiss and rumble on the entire recording, from interaction
with the receiver's sync detection (Sony 2010).

You not only get the favored rain-barrel acoustics, but there's
a great clatter in the background throughout.

This is the _designed_ result, not some interference with some other
noise source.

You can't use a sync detector on an IBOC AM station unless you get
both sidebands. The digital carriers are 180 degrees out of phase so
that they cancel each other out in a regular receiver.

This is interesting. How many radios besides the AR7030 have this type
of sideband?

The Drake R8B can tune upper, lower or both.
