<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>for your easy reference I do include the wording of
the email of Joe Subich as follows:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV>Rudolph, <BR><BR>The issue of uncommanded speed changes with WinTest and
<BR>microKEYER is absolutely an issue in the way WinTest <BR>controls WinKey
speed. It happens also with a "bare" <BR>K1EL WinKey and it does not
happen with the other leading <BR>software. <BR><BR>Well over a year ago I
posted information on eliminating <BR>the issue. Other authors have made
use of that data to <BR>eliminate the uncommanded speed changes but it appears
<BR>that WT has not. The key portions of that information
<BR>include: <BR><BR> 1) A program should never use "Change Speed
Buffered" <BR> (<1C nn>) except for temporary
changes within a <BR> macro and their use should include
a "Cancel Buffered <BR> Speed Change" (<1E>)
command at the end of the <BR> macro. <BR> 2)
always add a WinKey "Set WPM SPEED = 00" after <BR> the
macro has completed (when WinKey signals PTT <BR>
released or busy=0) to reset the speed to that <BR> set
by the pot<BR> 3) always include a "Set WPM Speed" command at the
<BR> start of a macro to sync WinKey to the speed the
<BR> program believes it should be.<BR> 4)
(helpful but not required) poll WinKey for the <BR>
current speed whenever receiving an unexpected <BR>
(uncommanded) speed change. This will help to <BR>
filter "excessive" speed changes due to RFI <BR> 5) (helpful but not
required) ignore speed changes <BR> from WinKey of +/- 1
WPM as this could be "noise" <BR> in the speed pot A to
D converter. <BR><BR>The microHAM implementation of WinKey is completely
transparent; <BR>Router makes no changes in any data to or from the WinKey IC.
<BR>Any speed changes are entirely generated by the application or <BR>user.
