Gee, with 2 radios and 2 soundcards, you can sure do some interesting
things!  http://wa9als.mystarband.net/mixwin.gif - This shows
transmitting with the 706 and MMTTY via the Soundblaster and receiving
with the PROII and MixW via the Integrated Sound!  Although the signal
was outside the expected passband at the default MixW setting, it was
easy to shift it up to where the 706's signal was, then turn on AFC to
lock on.  However, there was still no print, as seen before with MMTTY.
If the shift (170) is also being altered by the Integrated Sound, it's
only slightly visually apparent.

It's interesting to note that MixW has more versatility in setting up
the souncard.  In the first place, it lets you choose which
Windows-recognized sound card you want to use, BY NAME as opposed to the
MMTTY choice of DEVICE ID - this is really nice!  Then you can choose a
sampling frequency and a "clock adjustment" in ppm.  There are also 4
DSP filter choices on the Soundcard Settings screen.

I gotta go - I think I've been talking to myself too long!  ;-))  At
least I haven't blown a front end talking to myself.  Sure hope there
are some REAL signals on the air later today!  73
