Tony, most interesting information. Many thanks for posting. Please
email me offline about your testing. I would be most interested in
participating if possible.

>Jon,
>I have no idea about DSTAR, but did do some path simulator testing
with WinDRM and the latest variants as well as the AOR fast modem.
Nothing serious, just some informal testing from >PC-to-PC.
>The modes were tested for sensitivity and the ability to fight
ionospheric distortion. Some QRM tests were also done by mixing on-air
QRM with the digtial voice signals.
>They all sound great and work well with a clear channel and high
signal-to-noise ratio, but the better mode shows itself when the going
gets rough.
>It would seem that the latest WinDRM variant offers the the best
compromise between audio quality and robustness. We are still beta
testing the mode with on air testing when we can.
