Some further observations on the WaveTool utilities. <br>
<br>
1) These are actually 16-bit Windows 3.1 programs, but they work
well on 32-bit Windows 2000 and Windows XP systems. They will NOT
work on Windows Vista or Windows 7, since the 16-bit compatibility
layer (a.k.a. the "thunker") that has existed in 32-bit Windows
since Win 95 was quietly dropped in Vista and beyond. <br>
<br>
Note that this breaks many older supposedly 32-bit programs. Many
early Win95/Win98 "32-bit" programs contained chunks of 16-bit code
(especially device drivers) recycled from their 16-bit Windows 3.1
predecessors. Such programs depend on the thunker to seemlessly run
the mix of 16- and 32-bit code. <br>
<br>
2) Windows XP allows multiple applications to access the sound
card simultaneously. The WaveTool scope or spectrum analyzer can
run AT THE SAME TIME as the AGW Packet Engine, APRS Messenger,
mmSSTV, MixW or other other sound card app for a REAL TIME display
of the incoming signals being fed into these apps. <br>
<br>
3) The WaveTool scope in dual-trace mode can do the tricks
"real" scopes do of displaying A-only, B-only A and B, A-B, A+B and
A vs B vector displays. <br>

<pre wrap="">With today's sound cards in every PC, surely there is a free
O-Scope display. If so, then there is no excuse for any ham to
not use this tool for cleaning up some of the trash we see on
144.39.

There is a very simple and FREE app for this on my website. <br>
<br>
Go to <http;//wa8lmf.net/miscinfo> <br>
<br>
Scroll down the list of downloadable stuff and look for <font
face="Verdana"><a moz-do-not-send="true"
href="http://wa8lmf.net/miscinfo/WaveTools.exe">WaveTools.exe</a>
. <br>
<br>
Right-click and download this self-extracting archive of 4 audio
applets for your sound card. <br>
<br>
Four separate small programs turn your sound card into a
dual-trace audio scope -or- a sine/triangle/square-wave audio
generator -or- a volume-unit meter -or- an audio spectrum
analyzer switchable between a linear and log scale. <br>
