The firmware birdie removal took care of every bothersome birdie (and I
am a stickler about weak signal performance) except for one that was
still an S2 or so ... and that was in a portion of the band that I don't
care much about.
I did play around quite a bit with cable placement (see humorous note
below) to prior to using the firmware fix, and didn't necessarily find
the best arrangement to be the ones that Elecraft recommends. By the
way, the best layout is quite dependent upon whether or not you have the
2nd receiver installed.
Of course the firmware birdie removal won't remove them from the
panadapter ... don't know why you'd think it would. If you read the
description of how it works it simply shifts them out of the normal
listening passband, but they will still be in the IF window.

Note: Prior to the firmware fix, I tried all sorts of things to reduce
the birdies. Once I got the cable placement as best I could, I even cut
up sheets of carbon impregnated foam, put them inside of plastic
sandwich bags, and stuffed the K3 with them to hopefully absorb some of
the coupled energy between cables and various metal parts. It was a
total waste of time. ;)

Hi,
Can you give me a list (frequencies) of your worst birdies and I will check
if I have them. In general I have not found many bothersome birdies in the
K3S, but there are some. If I don't have them, there is clearly something
wrong with your radio which may warrant a return to Elecraft. BTW, I don't
have much faith in firmware birdie removal. It certainly doesn't remove
birdies in the panadapter display (LP-Pan and NaP3 in my case).

I LOVE my K3 … It’s the best radio I’ve owned (and I’ve owned
many/most/all of the very best)., except on AM where my old Orion/Orion II
(the ones I sold to buy the K3) were much better … but that’s a different
issue. (And E’craft won’t “formally" deal with it). Everything else
about the K3 is FAR superior.
After, I don’t know 8-9 years of ownership .. ALL (and I do mean ALL)
hardware/software updates have been applied, including the new K3S boards
that have been made available. So it’s as up to date as possible.
Still — the age old issue of “birdies” has been an elusive problem to
solve.
Just for the record .. I have 2x KYSYN3A’s installed, a subreciever, and
the other usual updated stuff. I’ve fiddled for hours with the birdie
removal routines in firmware. And yet — they’re everywhere. Most are low
enough in signal strength to ignore — but there are many LOUD ones here
and there on 80/4020/and elsewhere that are just “there”. Nothing really
helps. I just spent an evening fiddling with cable placement AGAIN, to no
avail.
I’ve followed carefully all of the cable routing instructions provided by
Elecraft. To no real effect.
So my question is — has anyone found a SOLUTION?? I’m considering sending
my radio to CA, but I'm concerned that after spending the $$$ to do that I
won’t be any better off.
To be clear — this isn’t a deal killer by any stretch … just looking for
input.
