K3 Birdies
Locked
 
|
I recently installed the KRX3 and seem to have some of the
birdie problems
others have noted, the loudest on 14.186.7 (S3). The
others are masked
when connected to an antenna and are not a
problem.
I have tried adjusting the cables and saw some improvement
but it will
not be a solution as Wayne noted. Has anyone tried
the test firmware
that Wayne mentioned a week or so ago?
Thanks all,
Bob W6VY

Bob,
I've had very positive feedback from a dozen or so K3 customers who 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. 73, Wayne N6KR On Feb 20, 2009, at 3:31 PM, Robert Dorchuck wrote: > I recently installed the KRX3 and seem to have some of the birdie > problems > others have noted, the loudest on 14.186.7 (S3).

Ditto! Works very well on fast moving birdies. Other junk,

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 KRX3 all at once before I checked for birdies so I don't have a comparison, but I have suspected that there are stronger birdies with the KRX3 than without it. The most obvious reason would be the additional TMP cables, but I'm not sure that's the culprit. I half suspect that the shield of the KRX3 (which does an excellent job for the KRX3) couples signals to the main receiver. I used a wide flat blade screwdriver to short the shield of the KRX3 shield to the case while monitoring the birdies, and I found that the birdies were VERY sensitive to where on the KRX3 shield I did that. It's possible that the screwdriver blade was acting as sort of an antenna, but I doubt it since the birdies always decreased in strength when I found the right spot ... I never found a spot where the birdies increased in strength as a result of my playing with the screwdriver. 73, Dave AB7E Robert Dorchuck wrote:

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 removal feature and now it's gone. 73, Rich VE3KI Bob W6VY said: I recently installed the KRX3 and seem to have some of the birdie = problems others have noted, the loudest on 14.186.7 (S3).

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 tedious. 73 -- Joe KB8AP On Feb 20, 2009, at 3:36 PM, wayne burdick wrote: > Bob, > > I've had very positive feedback from a dozen or so K3 customers who > have used the new "birdie removal" feature successfully.

The patch will NOT remove computer junk, it was a tongue-in-cheek comment.

How does one acquire the birdie removal software and it is only usable
if you have the second receiver? ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

The "birdie removeal" software is an upcoming revision of the MCU firmware.
Ask Wayne ([hidden email]) for an early copy. Before too awfully long it'll be available to all on the K3 software web site as a Beta version. 73 de Dick, K6KR -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of SidShusterman Sent: Friday, February 20, 2009 6:16 PM Cc: [hidden email] Subject: Re: [Elecraft] K3 Birdies How does one acquire the birdie removal software and it is only usable if you have the second receiver? ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

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 direction. Birdies near a 100 Hz boundary (i.e., 14174.101) often require both ... a shift in one direction for one 100Hz segment and in the opposite direction for the adjacent segment, but even that generalization is not always optimum. Since the birdies are mixer products of UHF harmonics and their strength varies from rig to rig depending upon cable placement, I don't think it's going to be very practical for the software to try to know what generated a birdie on any particular frequency in order to decide how best to remove it. For me, I'm just glad to be able to remove them manually. 73, Dave AB7E Joe Planisky wrote: > 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'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 segment with just noise. (I'm also not proposing that it scan the whole band looking for birdies. I'll do that. But when I find one, I'll hit a button that says 'take it out'.) 73 == Joe KB8AP On Feb 20, 2009, at 7:21 PM, David Gilbert wrote: > > Personally, I don't think that's going to be likely.

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. It might be sonically entertaining, too. 73, Wayne N6KR On Feb 20, 2009, at 9:05 PM, Joe Planisky wrote: > 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 segment with just noise.

I have had success in eliminating "birdies" using Waynes new program. I think the existing approach is sufficent in that you only have to do it once/birdie. So its no big deal. As Wayne noted some birdies requie more than one shift and its not clear [to me] when to shift up or down. Would guess with time I will understand that.
So help is on th way!!! Larry moore w6od
