Just listen to 80m at nite and this is what you will get with channelized P4 digital venue.
This whole line of discussion is doing a wonderful job of turning the reflector into an email version of the same. Congratulations.
I myself happen to be one of the volunteer developers of the digital software, and am in a state of continual astonishment at the sense of self-righteous entitlement expressed by some of the commentators here. What is the point of amateur satellites if not the advancement of the radio art?
If you ain't part of the solution, you *are* the problem.
Without getting into the personal aspects of this, I think it is important that one point be made clear for those who haven't been closely following the design of software defined transponders and the advanced digital package. The former technology (abbreviated as 'SDX'), in its usual configuration, provides a linear transponder which, to the ground station, will be functionally equivalent to the ones we use now. It is easy to get confused and think that SSB/CW, etc. will not work on this because it is 'software defined'. I understand we'll have a chance to try this out in space on Suitsat2; can't wait -- got a school class all lined up, too.
In contrast, the digital package will support various digital modes including a messaging system that will make much less demand on the ground station from a radio standpoint.
Around here, 80m facilitates some excellent conversations and some poor ones. That's the nature of human communication, in my experience. I don't expect Frank Bickle and others to solve *that* problem, too :-)
