[Elecraft] KIO2 noise problem

[Don Wilhelm]

Scott,

The only thing I can think of is either a very noisy computer or that the
cable shield is connected at both ends (that is likely to produce ground
loops and those do create noise).  Check your cable again to be certain the
shield is connected only at the K2 end - no connection to the shield at the
PC end).
