Not just any 300-baud modem, unfortunately.  Some folks up in Ottawa,
including a friend of mine, did a CHU receiver at one point.  They ended
up custom-brewing a modem.  The problem is that the 300-baud carrier is
not continuous, and commercial 300-baud modems take too long to lock onto
it -- you need something that will lock on almost instantly if you don't
want to miss the start of the data.
