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.

Has any testing been done on the DV modes above? WinDVM sure looks
attractive as no additiona hardware is required. Thanks for any/all replies.
