Hi all,

 

its no longer a secret :

Stefan and Markus found a carrier at 8970,022Hz on Stefans and Ge= rhards grabber and I had to confess that its origin is my QTH because the= TX was switched on at 1740UTC yesterday and that matches the visibility= of the carrier on Gerhards grabber.

 

My aerial: pse see

 

h= ttp://dj8wx-dl.de/hompage500kHz/TX%20equipment.htm

 

second last pic on the site. The 23m long wire has been lengthene= d by an other 20m.

The radiasls have a overall length of  500m.

 

I tried a measuring of the current between  the footpoint of= the matching coils and the radials:

Sri, but the meter doesnt show more than 200mA and its far >= than that.

 

The TX bumps 7,5A at 284Vpp (753Wrms) into the field coil of 134u= H (Z 7,5 Ohm).

 

The diameter of the circuit single layer winding coils: on averag= e 60cm.

inductivity: 245mH.

 

The generator is a homebrew BPU lf-exciter with the possibility= of all usual kinds of modulations.

 

The class E PA makes 2,4kWrms on NF. I could get 1700Wrms out of= this (misused) disco PA on 9kHz.

When I did so the consequence was:  One couldnt touch any ga= rden hand tools or other things longer than 50cm.

Txing with 750W: My XYL doesnt shriek any more when working in th= e garden and touching p.e. the barrow.

 

Best regards

Uwe/dj8wx still txing a carrier on 8970,022Hz. In some days Ill= send in qrs6000.

VLF,

Someone is transmitting on 8970.022 Hz, visible in my "DFCW-6000" window=
and visible at OE3GHB! It is neither Markus nor Ossi nor Gerhard nor me,=
so who is it??? :-)
Frequency is very accurate over time!

On 8969.97 i am doing a local test so pse don't wonder.
