[Elecraft] Mac Grounding

[Phil Hystad]

Follow up on some of this discussion...

Any wiring made to an Apple computer that is not supported via
standard cabling (e.g. USB, Firewire, etc., video, etc.) is not
authorized and may violate the warranty.  This is essentially what
it says in my iMac 24 user guide.  I did not quote it exactly since
it is about 3 paragraphs long with really tiny print.

As far as I know, I do not have an RFI problem in my shack and 
I am certainly not going to ground my computer (other then the
grounding plug for the 120 volt AC connection) nor will I put
a ground strap wire on my laptop.  I mean, does anyone really
do that?

But, like I said, I do not have any hum, buzz, or RFI that I 
know of and if I don't know of it it certainly does not bother me.
