[Elecraft] K3S K-line cabling

[Bob McGraw K4TAX]

Just purchase the correct cables from Elecraft.  This approach works 
100% of the time.

Go cheap, dig out your own or roll your own.  Then trouble shoot the 
issues.   How much money and time was saved?

For a few dollars saved, it isn't worth it.
