Steve,
The hash between FM channels who are broadcasting in HD is indeed awful. It
usually wipes out both the channel above and below the carrier frequency for
DXing purposes. I have noticed that during powerful eskip openings, signals
will sneak through. But overall, it really takes a lot of the fun out of the
hobby.
