Thanks Rick,
My Antenna situation is temporary. I purchased a Hustler 6BTV from DX
Engineering am working on getting it installed. It may take several weeks as
I work full time and am working towards my MBA full time. I may shuffle the
project priorities around and work on the Coax routing
You could try setting up counterpoises for the ham-stick. If it's for the
20m band, then ra few adial wires about 5m long should help. Connect to the
earth side at the base of the ham-stick. They're 1/4 wavelength so if tuned
correctly will act as a low impedance to the RF energy at the base of
It really sounds from the posts as if the radio and everything connected to
it was acting as counterpoise to the ham-stick. This is dangerous because
it means your radio is acting as part of the antenna. You don't want to
touch antennas while they are transmitting, especially at higher power.

Jerry,
Ignoring how you've set up your station for the moment (every station
has compromises but some push that to an extreme); the shutdown of the
connection is likely that RF got into the USB cable (as demonstrated by
the hot ferrite) which caused the USB port hardware to lock up.

Hi, Jim.
I think he was talking about the ferrite core embedded in the USB
cable. Check the title of his post.
But for sure, his setup is a really poor one.

That's an "un-natural act" -- the antenna is not designed for that
application, and, among other things, requires a good

Are you saying that’s what’s causing the ferrite core on the USB cable to heat
up?

You're safe, but obviously your K3 isn't...

I’m not sure, but, it’s a good point. I’m only running 50Watts.

With your antenna that close, are you sure you're not exceeding human
body RF exposure requirements?

Today I was working a digital mode (FT8) and lost connection to the radio. I
cycled power with no success. On reseating the USB connection at the
computer I felt the ferrite core was HOT. The cable didn't feel hot at all.
I'm using a 20m hamstick in the office as my antenna. I shut everything down
