[Elecraft] Vedr: K3 and MicroHam USB 3 issue

[Guy Olinger K2AV]

Hmmm.   RF in the shack is famous for causing troubles that make no sense
whatsoever and go away when substituting things, or changing cables, etc.
 See if the problems stop if you reduce power to 5 or 10 watts.  If it's
really RFI, you will chase your tail forever with the other changes.  One
person who shall remain nameless was going to send his K3 back, because a
problem in his digital setup would go away when he put his hand on top of
the K3.

73, Guy.
