What does HD have to do with DXing???

HD-AM transmits the digital data as two sidebands 20 kHz either side
of the AM carrier, so if you have a local HD station and want to
listen to a distant station that's on one of those "second adjacent"
frequencies, you've got a bunch of local RF. Something like 1% of
the stations analog signal power, but that could still be a lot of
interference.

Each one of those sidebands is 10 kHz wide. Contrast this to
DRM, which doesn't bother to transmit an analog signal and only
uses 9 or 10 kHz of bandwidth centered around the assigned frequency.
