What do you mean by "spaghetti wire?" Zip cord of any type should never
be used around transmitter sites because it is really poor at RF
rejection. Twisted pair is MUCH better -- it provides 30 dB or more
rejection of noise and RFI as compared to parallel wires (zip cord).
Over the years, I've cured a lot of RFI to home stereo systems by
replacing zip cord, glorified or otherwise, by twisted pair. In North
America, at least three very good cable companies, Belden, Gepco, and
West Penn, all manufacture twisted pair cable sized in the range of #13
to #10.
We can easily "roll our own" twisted pair simply by buying two colors of
stranded wire at the local big box store, spooling out needed lengths of
both colors, sticking one end of both conductors in a vise and the other
end in a drill, and twisting. Works great!
