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?

Subject: [Elecraft] USB Noise core gets hot when operating FT*? 

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 
to cool off. Afterwards everything seems to be working correctly. 

Any ideas? 

Tnx and 73
