Over the past few years, I have been toying with the idea of developing a
Quadrature noise blanker. This might be just the thing that can remove that
digital sideband noise from the adjacent channels of the IBOC stations.
Listening to the frequencies between 1100 and 1150Khz in the Chicago area in
the evenings is a joke. With the various stations' sideband noise
encroaching on each other, it sounds like somebody had a noise vacuum
cleaner running all of the time.
The IBOC folks did a good job of starting to ruin the MW band.

You can thank folks like 'Eduardo'!
