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 is

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 conce

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
