Birdies
Locked
 
|
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.

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). AB2TC - Knut

Obvious questions ....
Do the birdies (mostly) go away when the antenna is disconnected? Could they be coming from in-house sources? Are they there when the receiver is operated (on a battery) away from potential sources? 73!

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. Dave AB7E 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. ;) On 3/8/2017 7:30 PM, ab2tc wrote: > Hi, > > Can you give me a list (frequencies) of your worst birdies and I will check > if I have them.

I might fiddle some more with cable placement. I also plan to clear all of the signal removal data and just rework it.
I had the birdies cleaned up with the removal tool in most areas of the bands I operate. But since relocating the middle of last year into an “antenna free” zone, I’ve been primarily using my KX3 with various temporary and stealth antennas. Had the K3 out the past couple of weeks to put a couple of updates in, and while tuning around to make sure everything was working again, really noticed them. Most likely I didn’t get the various cables back in the same place they were the last time I had the radio torn down, and that affected the previous removal settings. As someone suggested, it might be external signals, but they move backwards like a birdie and don’t show up on the KX3, so it isn’t likely. It didn’t help either that at least part of the time, I had no antenna connected, which made even the weak ones that normally get buried in band noise stick out … :-) > > 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.
