Tony, sometimes if you'll take an am radio and sit it next to your short wave
receiver you can tune the am rig to get a beat frequency against the short wave
receiver that will let you receive sideband.  SSB is the removal of the carrier
from an am signal in its simplest form and beating a frequency against it from
another radio puts that carrier back in.  Just speeding up a recording will only
give you faster ssb to listen to and it will still sound like garbage.
