Dear Mal,
well I would like to persuade you into getting a
NOV and setting up to transmit on 9 kHz.
If I understood the info on your antenna system
correctly, you have a total of 600 m of wire in the air, at a maximum height
of 30 m. With a capacitance of 3 nF, and assuming a safe
operating voltage of 20 kV, you could bring a current of 3.3
A to probably 25 m effective height. Depending on your ground system,
you might need to put in about a kilowatt for this.
You would then radiate approximately 10
mW, slightly more than what Stefan can currently achieve with his 100 m kite. At
a time of low QRN, such a signal would most likely appear immediately
on the German grabbers, and would probably be detectable across Europe. I also
believe that there would be quite some interest in crossband QSO's
(9 / 137 kHz), which would give less equipped stations (like myself) a
chance to participate in the dreamers' DX.
Think about it - I'm sure you won't be wasting
your time ;-)
Best 73,
Markus (DF6NM)

Subject: LF: 9 kcs
What is happening on 9 kcs, some seem to be
aiming for earth induced signals downward penetration with earth rods etc
while some are trying elevated antennas for long haul.
I am interested in elevated antennas long
haul experiments but I think I am wasting my time.
The chance of me hearing some of these signals is
non existant bar a Miracle. Information is also scarce in the UK especially
about receiving capabilities, what is being heard especially alpha signals,
strength, audibility and general band noise.
