Your old radios will still work; the high-definition (HD) signal
that's currently in use is compatible with good old-fashioned AM
receivers. This is because the digital information is placed (in
frequency) above and below the analog signal. There are couple of HD
stations here in the Washington DC area, and on any AM receiver I've
used so far, including my antique tube radios, this digital "hash" has
not bleed through to the audio stages. When accurately tuned to an HD
station, the voice and music sound just as it always has.

That's total BS. All the highs are gone.
