[Elecraft] K3S K-line cabling

[Gmail - George]

Jack,
Don't use a 15 pin straight through - not all pins are to be connected. My 
recollection is that 1 or 2 pins Must Not be connected to the K3!
Use the manual if not using the Elecraft Aux cable sets.

Because not all VGA cables are the same - you can use a VGA cable if you 
positively confirm that all 15 conductors pass through and No conductor is 
hooked to each other.
Some VGA cables tie the coax shields together at one or both ends - these 
cables should not be used. I had a half dozen VGA cables - the second cable 
I checked was one to one with no pins shorted together. I broke off the 
pin(s) not to be connected and voilà free cable from the junk shelf.

If in doubt - buy the Elecraft cables or make your own from the information 
in the Elecraft instruction books.

I recommend using the Aux cable sets to interconnect the K3, KPA500 & 
KAT500. The seem to operate as a single unit in 3 boxes.
Only thing I'd love to see is for the K3 "Tune" button to put the KPA500 in 
Stby & Tune the KAT500.

Hi David! Great to hear form you...

     . . .

Lastly, be sure to use a cable with all 15 pins connected straight through. 
Do NOT use a VGA cable. They play with the signals in those cables, 
connecting several together, which will mess things up for us.

Hope you are enjoying CQWW this weekend; we miss you in NCCC!

73!
