Hi Peter,

To get a numeric indication of the noise floor, I suggest to use the lower-quartile algorithm. In SL, you would also define the frequency range in which to measure the noise. You can put the display on one of the 'programmable buttons' on the left side of the main window. Details:

http://www.qsl.net/dl4yhf/speclab/controls.htm#programmable_buttons

http://www.qsl.net/dl4yhf/speclab/interpr.htm#noise_func

Example to put this all together (as an expression for a button's text).

"Noise: "+str("###0.0",noise_n(300,2700))+"dBfs"

73,

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.
