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". 73, Ed - KL7UW ------------------------------ Message: 15 Date: Wed, 8 Sep 2010 08:29:01 -0400 From: John Fritze <[email protected]> Subject: [Elecraft] [K3] birdies and cable routing?

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