F5VIH gave me the big clue - do NOSOUND and the stuttering goes away. Note that
I was hearing the stuttering both on the sidetone from the computer AND on the
actual CW sent via LPT1 (PCMCIA plug-in card), but turning off the sidetone on
the PC gets rid of it - I'd previously just muted the PC sidetone with the PC
audio controls, but killing it at the WinTest level did the trick. CPU is still
high, but not giving any problems now. </FONT></SPAN></DIV>

getting the gear together for Moscow - have finally nailed a USB-SERIAL adapter
that works as well now - no luck with the Prolific chipset or the real generic
cheapies that are around, but the FTDI chipset seems to play ball.

style="FONT-FAMILY: Arial; FONT-SIZE: 10pt; FONT-WEIGHT: normal">While
trying to get WinTest configured on an old laptop I've run across a problem
with stuttering CW (both as sent from the LPT port and in the sidetone
generated by the PC). The computer isn't fast (Toshiba R100 1.1 GHz
Pentium-M, Win XP SP3, 1.2Gb RAM), but itbs not an old dog either. I've done
al the usual stuff of running ccleaner, defrag the disk, checking the disk
cache isn't partitioned etc.<BR></SPAN></DIV></BLOCKQUOTE>

<DIV>I just tried WT 4.4 on a very similarly equipped IBM ThinkPad X40 (1 GHz
Pentium-M, WinXP SP3, 1.2 GB RAM) using a real docking station LPT port for CW
(as well as the DTR line on COM1). No stuttering heard (except in the PC
speakers, which is "normal"). Try NOSOUND [Enter] and listen only to
your rig's sidetone.</DIV>
<DIV><BR></DIV>
<DIV>Is your rig in QSK mode or semi-breakin VOX or is it relying on PTT from
Win-Test? Did you try rebooting the PC? Disabling
AutoProtect?</DIV>

<DIV><SPAN
style="FONT-FAMILY: Arial; FONT-SIZE: 10pt; FONT-WEIGHT: normal">I find that
I can get the CW to go normal if I turn off the 'How many minutes since last
QSO' bar in the status window. Importantly I also find that running that bar
raises the CPU utilisation on the computer from around 4% to around 25%
which seems an inordinate amount of CPU to just display that
bar.<BR></SPAN></DIV></BLOCKQUOTE>

<DIV>Interesting. Maybe there's a graphics library or DirectX
dependency. Run C:\WINDOWS\system32\dxdiag.EXE to display the current
version. My X40 is running DirectX 9.0C and all pages report "No
problems found."</DIV>
<DIV><BR></DIV>
<DIV>Perhaps your display resolution or limited no. of display colors is
causing excessive CPU time to calculate the colors for this bar? Does it
work any differently if you use only an external monitor?</DIV>

style="FONT-FAMILY: Arial; FONT-SIZE: 10pt; FONT-WEIGHT: normal">As a
reference, I don't see this problem (or the high CPU from the status bar) on
a P4 1.6 GHz desktop. Win Test version is 4.4.0 in each
case.<BR></SPAN></DIV></BLOCKQUOTE>

<DIV>Open up Windows Task manager, click on the <B>Processes</B> tab,
then click on the column header labeled <B>CPU</B> (<I>not</I> CPU Time,
but <B>CPU</B>). The click on <B>CPU </B>again. This will sort in
reverse order, telling you which processes are currently using the most CPU
time. That will give you important information.</DIV>
<DIV><BR></DIV>
<DIV>While CW is sending and the timer bar is moving on my ThinkPad X40, I see
very little CPU being used by Win-Test.</DIV>

Win-Test doesn't place any requirements on the Java version on the PC (this
machine has had a few different versions of Java for work - otherwise it's
pretty normal).</SPAN></DIV></BLOCKQUOTE>
<DIV><BR></DIV>
<DIV>Win-Test doesn't use Java at all; it's written in C++. But it may
have a dependency on DirectX or the Windows Graphics libraries or the color
settings of your display. I'm using 1280 x 1024, 32-bit color. Are
you driving two displays at once or only the Toshiba laptop display?</DIV>

<DIV>Win-Test usually sends good well-timed CW via LPT or COM port, but you
still need to hook up your paddles to a separate keyer wired in parallel.
The only time I've heard any kind of stuttering is if I tried to use the
menus while Win-Test was sending via LPT. Other than that the CW timing
always sounds great, though I wish it offered WEIGHT and Keying Compensation
(K-Factor) options while keying via LPT or COM pins).</DIV>
