Bob,
Thanks for the info. I did read K9YC documents which I found quite
informative but the question on how many turns really was not
specified. I was hope someone could point to a study that might relate
the number of twist to effectiveness at different frequencies or
conditions. I searched google but have found one yet, but I do know
twisted pairs work very well. It is interesting to note that each pair
of wires in a CAT5/6 ethernet cable has a different number of turns to
prevent cross talk between pairs. Therefore some one must of figured
this out.

Hi Chuck,
Using twisted pairs is always a good idea. You might wish to review
the tutorial written by Jim Brown (K9YC). http://k9yc.com/RFI-Ham.pdf

Currently getting back into ham radio and re-wiring my station. I
would like to eliminate as many spurious signals as possible. Does
it make sense to put the red and black zip cord used for DC power
feeds in a drill to twist it to reduce and cross talk and coupling of
stray signals? If so how do you determine the number of twist per
foot for effective results?
