have used the new birdie removal feature successfully. This will be
included in the next beta release.
But don't take my word for it :) I'm sure others will weigh in.

The software fix works extremely well. I haven't found a single birdie
yet that I couldn't handle. Done properly, they go completely away.
I'm curious, though ... did adding the KRX3 accentuate the birdies
compared with how it was before you added it?
I built my K3 and installed the
It works a treat on fast-moving birdies (the ones that flash across the
bandpass as you tune slowly by them). After reading your message I looked
for and found one near there - on my K3 it could be heard between about
14187.15 and 14187.3 kHz - I made a couple of adjustments with the birdie
I agree, the birdie-be-gone feature seems to work quite well at
removing fast tuning birdies within the limitations of its current
implementation. I hope there will eventually be software commands to
allow the process of removing a birdie to be automated. It's not
hard, just a little
The patch will NOT remove computer junk, it was a tongue-in-cheek comment.

Bill,
I looked through the archives but can't find the sig rmv patch. Can you

How does one acquire the birdie removal software and it is only usable
if you have the second receiver?

Personally, I don't think that's going to be likely. The birdies don't
all tune in the same direction, and they all aren't in the same position
relative to a 100 Hz boundary. As a result, some birdies are best
removed by a shift in one direction, and others by a shift in the other
I'm not suggesting that it would be possible to calculate a solution,
but rather provide audio feedback to a program so it could do what I
do: listen for a tone, adjust the shift until it disappears, tune up
(or down) to the next 100 Hz segment, adjust the shift, repeat until
you hit a
I could change the firmware so that when in you're in the SIG RMV menu
entry, it could slew the VFO over the present 100-Hz segment (i.e.,
from .000 to .099) once per second. This way you could hear the full
effect of each SIG RMV step without having to exit the menu and move
VFO A manually.
Waynes firmware seems to work very well in eliminating birdies. As he has
noted it envolves shifting the 1st LO and BFO slightly [less than 100Hz]
which in turn moves the birdie some 1 to 2 KHz.
As usual Elecraft [Wayne] resolved this likely solution --PDQ-- once the
problem was

My experience is a definite yes. However, if you spend some time in
position the cables, the birdies can be reduced. Some patience is required.
