This second PC really needs more RAM to avoid swapping, but I'm not sure if
that could affect how quickly commands are sent from Win-Test to the Winkey
(it might).

What version of Winkey CHIP is inside these microHAM boxes?  Win-Test
reports the detected Winkey version in red letters at the bottom of the
logging window when you first start Win-Test.

DL6ZBN provided a microHAM communications log between the Winkey and
Win-Test that showed no errors, even though there was a speed jump heard
(actually a failure of the Winkey to perform the Send Buffered Speed change
command that it received from Win-Test).  He also reports using a Winkey v10
chip, which may be the real problem.  It's a little tricky, but with the
covers off, you *can *replace the Winkey chip inside an MK2R/MK2R+ using a
long thin screwdriver, without having to completely disassemble the unit.
An IC pin straightener is recommended to be used on the new chip before
attempting to plug it into the chip socket.

A microHAM Winkey COM port communications log captured at the time of the
speed jump would indicate if Win-Test and the Winkey had a problem
communicating, or if Win-Test sent something "wrong".  In DL6ZBN's log,
everything looked fine.  It's as if the Winkey received the command, but
ignored it.

What version of Winkey chip do they use?
