Concerning the AOR DV...
I believe that you might be able to get two DV QSOs in the same 3 KHz channel at the same time...but I can't say for sure.
The problem with the AOR DV or Dream DV

Well yes...speed and robustness. Something down aroung -5 to -10 dB SNR on a poor CCIR channel and speeds that would produce 3-5 printed pages of information a minute. Pages Per Minute (PPM) is now how

know that Walt wants an ultra wideband unconnected mode for HF emergency

Walt,
Did you get a chance to try out SCAMP when it was temporarily available
as an experimental mode?
The average computer of today, 1 GHz, can handle some pretty strong ARQ
decoding. The concept of not being able to download the next block
while decoding seems to me to be an obsolete

My assumption of 100% utilization was based your saying The
composite signaling rate would be 51200 bps. If you're now
saying this is a shared-channel protocol design to support 4
users, then why not instead provide a single-channel protocol
that's *only* 4 khz in width? If we think about
