I downloaded the live flPuppy Live-CD today with fldigi 3.0 built-in
and have been playing around a bit with it and I am impressed. With
everyting in RAM it is sure fast. I saved everything and will see if
all is restored when I boot the computer again.

I am in the midst of a major reorganization of my radio
room and may dedicate a Kenwood TS-180 to digital modes,
including DominoEX and also sstv, dsstv, PSK31, etc ...
seems there are new digital modes or updates to existing
ones every week!
I need to find an affordable older laptop and run the
tiny Puppy Linux OS with digital modes on it. Possibly
an older IBM 600-series as they are very reliable and
lots of parts are available. Whatever I can be sure
will be natively compatible with Linux and will run
directly (if not charge the internal battery) on 12vdc.
WDYT?
