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.
