[Elecraft] [K3] birdies and cable routing?

[Edward R. Cole]

John,

As Wayne has stated, routing varies with individual radios, so what 
works for one may not be optimum for others (definitely a trial and 
error process).  A though occured to me, though.  Since cable layout 
seems to make a difference for some, I wonder if double-shielded 
cables would make any difference?  That would only if leakage is 
occuring.  If birdies are being conducted over the coax shields 
(common-mode) then perhaps a few ferrite beads would help?

This stuff is in the area of "magic touch" and hard to reproduce as 
"exact science".

  " He sent along a pictorial of a Italian gent
who has rerouted his TMP cables in such a way to
substantially reduce receiver birdies."


Perhaps Elecraft could post the photos somewhere so that we might
decide if it makes a difference in our individual rigs (mine
included).
