[Elecraft] K3S USB intermittently disconnects when transmitting

[Guy Olinger K2AV]

RF in the shack and/or voltage between equipment cases. Very easily can
come from handful of separate causes which will all need to be
fixed.  Numerous causes.

No common bond for cases in shack. Problem with grounding. Lack of common
entry ground where cables come into dwelling. Antenna is very close and
cables in shack need ferrite. Insecure connection in connector wiring. Ad
nauseum.

Time to clean up and get proper. Read K9YC's treatise for pin one problems.

Welcome to an old club with many members.

73, Guy K2AV
