John,

If this modulation is the MIL-STD/FED-STD/STANAG 8PSK waveforms, 
wouldn't they be at 2400 baud at all times? We can not use baud rates 
over 300 here in the U.S. on the text digital portions of the bands, but 
they could possibly be used in the voice/image portions for sending 
images/fax.

Possibly packets could be received as long as you are not linked and the 
program can send unconnected packets?

What will be extremely helpful is for any experiences you have with data 
throughput vs S/N and interference.

It is still curious to me that the promoters of "ALE" modes do not test 
these protocols in the voice portions of the bands. Also on 6 meters and 
up. There has been absolutely no measurements of S/N in real world tests 
on the amateur frequencies that we have heard thus far.
