Thanks Markus

for the info but it requires too much effort for me for ONE qso hi

It appears at present maybe a  couple of German stations would hear me but no one in the UK  seems equipped to receive, no one is responding to my request for information about their RX capabilities.

Why so much interest in 9 kcs when most cannot generate signals on 137 or 500 kcs and those that do are very weak, although there are some strong Dutch stations active on 500

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)

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.
