Big congratulations Riccardo !

You are 1233Km far from here, but detecting you and decoding will be a next challenge
One more amazed with the outstanding performance of Paul’s receiver :-O

Asunto: Re: LF: Little TX test at 8270.00046 from JN64
Many thanks for your efforts!
I'm running with a GPSDO at 16384.0000kHz clocking a DDS AD9850.
The output is divided by 4 (SDR quadrature generator). Tuning dword is 8671724.
Now only 90W from the audio amplifier and about 13kVrms on radiator.
Next days, I will try to find a better antenna match (and more power).
Antenna current is now oscillating due to a fresh breeze.

That's nice to hear - Stefan is running out of receivers
and I'm running out of transmitters!
I'm looking for you with
http://abelian.org/vlf/fbins3.html#b=160&s=fd&m=fb&w=r&c=1
but nothing shows yet. If you can launch 10 or 20 uW, it
is likely to be visible.
Later, when you've been on air a few hours, I'll run a narrow
band spectrum. You're locked to GPS I hope, otherwise
I have no chance at this range (1017 km).
Let us know when you switch off.
