Viktor et. al.

I can understand the interest in receiving the 9600 baud transmissions.

But isn't it true that there will also be 400bps transmissions just like 
AO-13, and for those we can use the same modems as before, but with a new 
program to be made available by AMSAT and w4sm?

thanks, ron.
