[Elecraft] KPA-1500 Fan Noise with added VGA comments

[Bob]

Not from Elecraft but...

Yes the caution is warranted for "VGA" cables.  They are not always pin for pin 
and can do two things wrong. One is that not all pins are wired and the other is 
worse as they sometimes tie the shields together shorting out needed pins. There 
are multiple versions of VGA cables.

My source for the correct cables is L-Com here:

I've had good luck with products from them being reasonably priced and good 
quality.  I'd just get the length I'd need rather than an extension.  An 
extension adds another failure point as with all  cabling jobs.
