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.

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