[Elecraft] Missing first piece of dash or dot when sending CW with K3S USB input with Wintest.

[Bob Wilson, N6TV]

I did not experience any problems like that during 24 hours of the IARU
contest keying a pair of K3S rigs with Win-Test over the USB line, in full
QSK mode, on a single computer (which was running Windows 7 32-bit).  With
Win-Test's excellent software CW timing, there's usually no need to buy a
WinKey.

The suggestion to check the USB Power Management settings is a good one.

I think further questions about this should be addressed in the Win-Test
reflector <http://lists.f5mzn.org/cgi-bin/mailman/listinfo/support>, since
this is unlikely to be a K3S problem.

73,
