[Elecraft] Snap-On Ferrites and RF Noise On 160M

[Merv Schweigert]

Another solution is to take the "zip" cord and pull it apart,  chuck two 
ends
in a variable speed drill and turn slowly,  it will make a very nice 
twisted
pair out of any guage.   Just be sure to use a length longer than what 
you need
as it looses length as it is twisted of course. 
To keep it in a tight twist I use small pieces of heat shrink spaced 
along the
wires at intervals.  I suppose one could use a piece of heat shrink over 
the
entire wire if you wanted. YMMV
