Very nice, Ric! Glad to see a new station venturing on Dreamer's band.

How far are you from Cumiana?

Hi Paul, VLF

 

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.

All the best

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.
