[Dx4win] Wish List

[Mel]

maybe you should ask Paul to consider supporting it. You could always 
make an optional cheaper 4 port version for radio control I suspect. 
Maybe some of the contest logger guys would be interested too. I'd love 
to interface it with a box to route Audio and CW lines as well as the RF .
