[CQ-Contest] HAL-DXP38 vs MMTTY

[k8gt at twmi.rr.com]

Everyone seems to be missing the obvious reason why MMTTY didn't work 
as well as the HAL-DXP38, and that is the soundcard.  Don't use the one 
on the motherboard, in fact, get a decent one with at least 96kHz 
sampling rate.  I found a Sound Blaster Audigy SE 7.1 Surround 
Channels, 96 kHz SR for about $30US online.  Now if I can only find a 
Linux driver for it.  :-(  Otherwise I'll have to run Winbloze.  :-(  :-
