Re: [Elecraft] K3S USB intermittently disconnects when transmitting
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.

Re: [Elecraft] K3S USB intermittently disconnects when transmitting
I first experienced this in a different room using a Buckmaster dipole at 35’. Issue occurred with 100w and with 40w, Only seems to happen with CW. I have been able to reproduce the error sometimes in test mode so no RF goes out (I’m currently attending CW Academy). I’ve changed offices and now use a 20m hamstick. I only intermittently have the issue when sending CW in test OR transmitting.

Re: [Elecraft] K3S USB intermittently disconnects when transmitting
Put a clamp-on ferrite with a turn or two through it and locate it at the USB port at the computer. Mine did that too, but only when using the amp on 160M. I figure it was a bit of RF being picked up on the cable. 73 Bob, K4TAX K3S s/n 10163 On 1/20/2016 7:44 AM, Jerry Moore wrote: I've checked the connections and can't seem to find anything to explain why the USB disconnects from my PC when transmitting.
