Hi Peter

I was just hoping that the signal is Henny. If the indicator is Green it seems all is OK and the line is indeed at 8.96995
and possibly local. Since looking at 8.999 to 9025 kHz I note a carrier on 9.000 kHz which starts at 10.00 to 11.00 and continues to 23.00 daily I suspect it is something local.

Hi Eddie,
I have set that 'Sampling rate detector" in SL.
I use 20k9 FTA, the indicator is Green, I have Enabled it.
What els have I to do ????
I use that Bandpas filter in the left Black box.
8970 Hz center, 500 Hz width.
Spectrum on L2
FTT input size is 524288
Decimal input by is 216
That gives:
Effect of FFT settings with fs= 48.0000 kHz:
Width of one FFT-bin: 423.855 uHz
Equiv. noise bandwidth: 635.783 uHz
Max freq range: 8.91444 kHz .. 9.02556 kHz
FFT window time: 2359.296 s
Overlap from scroll interval: 87.5 %
I did not callibrate it somehow. On 30 meters / QRSS I use that time sign on 9996 KHz. I don't know how to callibrate it on VLF.
I can't whistler that stable :-) 
That signal on 8.969,995 has a kund of fading. I hope it's not something local.
Feel free to inform me if I do somnething totaly wrong !
No hard feelings :-)

Very good, how is your calibration? Henny is on 8.97000 you have a line at 8.96995 if it stops at 23.00 that is when Henny is QRT.

Hello all,
Today I did plant the "PA0RDT Mini-Whip" antenna in the backyard at about 20 meters from the house and 4 meters above ground level.
Last 2 week I was using 2 pasive loop antenna's who where connected direct into the mike input.
That wasn't a succes...
I hope to see some results soon :-)
Take a look at the links below. I did start logging on Friday evening at about 19:00 UTC, so perhaps I have to adjust contrast later.
A page on QSL net  or direct to the grabber schreen plot

QTH is Appingedam in JO33kh, in the very North- East part of The Netherlands.
