[Ham-Mac] Update #2 on RFI and Right-Click Mouse Issue

I had a similar experience but the other way.  iMac connected to wired  
1 Gbps CAT5e ethernet causes noise on my HF radio (Basically beside  
each other.) I switched to wireless network and noise was removed from  
radio.

I also had a similar experience with a touch sensitive light fixture.   
Touch the base it goes on/off.  Transmitting at 100 watts (not a  
perfect SWR match either) caused the light to flicker on and off. It  
was band specific. Cool disco light however. :-)

I think mostly the issue is that USB wire becomes an antenna and/or  
they are sharing the same ground in shacks.  By going wireless you  
remove the antenna (the USB wire). I am pretty sure none of this  
computer gear is tested in RF field of the type/level we generate as  
HAMs.

Hummm... wonder how the neighbours are coping. ;-)
