font-family:Arial'>We’ve talked this subject to death and still both of
my MK2R’s running under WT begin erratic CW speed problems sooner or
later during a contest. I recorded a transaction log for OM7MM at MicroHam and
he said he could not see any anomalous behavior of the MK2R. <o:p></o:p></span></font></p>

relate it here because I would like for all of you to consider if the issue is
USB related.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I have six Green Heron rotor control boxes. With their USB
ports connected, I experienced extremely erratic behavior. It took many
restarts to connect to the GH server each time I shut one of the boxes off.
Sometimes, I had to delete and reinstall the drivers or the devices. I decided
to install an 8 port Serial card in the computer and all of the problems have
gone away. I have worked with W2FU in the past and know him to be a very
capable engineer, but I am also aware that USB protocol is massively more
complex than serial or parallel protocol. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Is it possible that the time has NOT YET come for USB to be
stable enough for our needs in ham radio, or is USB too complex for the amateur
to implement? Just a thought. The three groups involved in this issue need to
have a summit and fix this problem.<o:p></o:p></span></font></p>
