LF: Question about ground impedance at 8.97 KHZ Stefan.

["Paul A. Cianciolo" <paulc@snet.net>]

Hello All,

Below is a quote from the Stefan's web page concerning his latest "Dreamers 
Band" DX contact Congratulations again Stefan.

>system impedance.




"100m Vertical wire antenna, coil/antenna voltage was abt 15kV rms, average 
antenna current about 480mA, giving up to 1,7mW ERP. Applied power was up to 
250W."

Pertaining to the coil "Technical and mechanical data: L=553mH, Q=82, R(DC)=283 
Ohm; 0,4mm diameter enameled copper wire, about 1200 turns! Average diameter 
0,55m, height abt 0,5m. So, about 2000m wire! :-)"



I have built a small impedance bridge that operates at 10 KHZ and shows my 
sloping 170' wire as 70K Ohms. I can also see approx 500 PF that can be nulled 
out using the bridge?

Can the 70K value possibly be correct?   (3) 6' ground rods about 6' apart are 
the ground... plus the electrical ground of the house.

I am hoping to attempt a local transmission on 9KHZ 

Any information would be helpful.

Thank you

Paul
