Uwe,
Looks stable and very strong over the night.
That step in my 238 uHz window is because DHO went QRT for 1h.
I use DHO 23.4 KHz experimental as reference in only this 238 uHz window.
At 09h UTC today I did switch back to 22k1 as reference for Specrum Lab.
 
At 06h30 was your signal very strong today.
The cursor say's -116dB at that moment.
 
Where do I read the noise floor in Spectrum Lab ?
Average of the Yellow grab ?
In that case Noise is -140dB

Hi Uwe,
Between ~11 and ~16 h UTC today was stabillity perfect.
Befor 11 was a short break and also after 16 h
Not sure how it is right now.
The new traces are building slowly and the picture is not complete yet.

Hi Peter / Uwe

Maybe that explains why when I ran my my Grabber yesterday I could detect nothing. I haven't been running any 8.9KHz for a while as my WSPR on 474KHz makes a mess.

Hello Uwe,
Your signal is not very stable now.
 
 
It feels not good to me to complain about 0.001 Hz drift, but I hope you understand when you take a look at my grabber ;-)
 
Thanks anyway for all the experimental broadcast's.
