I would say that you simply have pin 1 problems in the gear that is 
detecting the RF, and the antenna is now working well enough that 
it's putting out enough RF to excite them. This MAY be complicated 
by the lack of a balun (that is, the feedline is radiating), and I 
would try to add a good one. 

For RFI fixes to the computer and audio gear, and an explanation of 
"pin 1 problems," see the RFI applications notes on my website. 
Grounding is NOT your problem. 

BTW - virtually ALL computer audio interfaces, most consumer audio 
gear, and most ham gear, have what Neil Muncy would call 
"screaming" pin 1 problems.
