[Elecraft] K3S/FT8/Mac mini Problems

[Bob McGraw K4TAX]

Sounds as though RF is getting into the computer. 

I had the issue and added ferrite cores to several cables. Including the one between the radio and computer. Some improvement noted.   Replaced the USB cable with a good quality shielded cable. Problem solved even at near legal limit.
