A couple of people on tonight's boot camp asked for info on common frequencies 
for digital on HF.

This is a link to someone's personal site where he has put together a good 
collection of frequency information.  References to "stream" are the sound card 
digital modes other than PSK31.

On HF digital sound card modes are sent via SSB.  Note two very important 
things:

	* The frequencies used for the digital modes are in the CW portions of the 
bands, even though you're sending SSB.  The FCC has approved that usage.
	* All of the SSB digital transmissions use UPPER sideband, even on 40 and 80.
Thanks all for participating.
