[Elecraft] Amplifier Cable:K3 to Alpha 8410

[Ron D'Eau Claire]

If you're after decent shielding to keep RF out of the circuit, Radio Shack
might have what you want. Nowadays a "high impedance" is typically 1 or 2K
ohms instead of the 50K ohms are more common a few decades ago. Audio cable
shielding has been reduced accordingly - especially from lower-cost
suppliers. Where audio cable shields used to look much like the shield on
good RF coaxial cable, nowadays it's common to find RS and other low-cost
cables have a "shield" that consists of a few strands of bare wire running
parallel to the insulated center conductor - maybe 10% or less shielding. 

For that reason I make my own using RF type coaxial cable. RG-174 makes
excellent lightweight shielded cables with a diameter of about 1/8".

I just use a regular old "phono" (RCA to RCA) cable between my K3 and 
87A.  Works fine.

assume that the end that connects to the K3 is also a phono plug.  Does
anyone have any suggestions looking through the Radio Shack website as to
the cable that would work the best.  Thanks for your help!  Mark KB3Z
