Re: [Elecraft] KX3 Spur/Birdie on CW Receive

[James Bennett via Elecraft]

OK - mystery solved! I had posted this on the Elecraft reflector and shortly 
thereafter realized it should have gone on the KX groups.io  
list. So, I put it there and THAT is where my answer came from. Now, why it 
took almost a week to get into the Elecraft reflector is another question. But 
anyway, my problem was fixed AND now I know why I’m seeing double! Sorry for 
all the confusion, folks.

BTW - the “birdie” thingy was resolved by the Tech Mode entry RX ISO - turning 
it ON got rid of the “birdie”. Thanks to JPE1HZG for clueing me in to that one.

 I’ve got my KX3 connected via an MFJ 178B-SDR switch to my computer

 Additional software syncs the KX3 with SDR++ and RumLogNG - a logging 
 program. Anyway, When I have the KX3 in CW mode, I see a birdie or spur 
 (not sure the actual name for it) about 500 Hz up from my zero-beat 
 frequency. As I turn the KX3 dial, the spur mores right along with me. It 
 is showing with a signal strength of about -79 db. Now I know that is a 
 really low signal, but it does show up on the display and is a tad 
 annoying. Actually, as I type this I’m on 10.116 and as I was testing, I 
 find that there was a low level signal there, under the birdie. The fact 
 it was being covered up bugs me a bit, too.
 
 No matter what band I go to, my little “buddy” is there with me. If I 
 switch to USB or LSB, it is gone - it only shows up in CW. And if I do 
 CW-R, it switches to about 500 Hz below my frequency.
 
 Anyone else have this? Is it something worth reporting to Elecraft, or is 
 it a known “thing”.

Wow - this is strange! I posted this last week and got an answer fairly quickly 
- it was a setting in the tech mode menu that resolved it. Thought it was all 
done. Then this morning around 08:30 local time I got a couple messages that my 
post had been accepted from the reflector, and it all started over again!

Anyway, the “problem” is resolved on my end and now it looks like something 
funky is going on with the reflector.

That should have been MFJ 1708B-SDR.

[Elecraft] KX3 Spur/Birdie on CW Receive

[James Bennett via Elecraft]

Folks - 

I’ve got my KX3 connected via an MFJ 178B-SDR switch to my computer running 
SDR++. This gives me a nice BIG pan adapter display on my monitor. Additional 
software syncs the KX3 with SDR++ and RumLogNG - a logging program. Anyway, 
When I have the KX3 in CW mode, I see a birdie or spur (not sure the actual 
name for it) about 500 Hz up from my zero-beat frequency. As I turn the KX3 
dial, the spur mores right along with me. It is showing with a signal strength 
of about -79 db. Now I know that is a really low signal, but it does show up on 
the display and is a tad annoying. Actually, as I type this I’m on 10.116 and 
as I was testing, I find that there was a low level signal there, under the 
birdie. The fact it was being covered up bugs me a bit, too.

No matter what band I go to, my little “buddy” is there with me. If I switch to 
USB or LSB, it is gone - it only shows up in CW. And if I do CW-R, it switches 
to about 500 Hz below my frequency.

Anyone else have this? Is it something worth reporting to Elecraft, or is it a 
known “thing”.
