Congratulations. I am already looking for your signal on 8970.= 022Hz and will let you know if I see it in 423uHz BW.=A0

My grabbe= r is active now centred on 8970Hz. See https://dl.dropbox.com/u/15047843/xbm_grab.jpg= . Please take a look to see if you become visible.

I will add you to the table on my sub-9kHz webpage shortly. Activity in Europe= is developing so fast that I am struggling to keep this table up to date!=

Hi all,

=A0

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.

=A0

My aerial: pse see

=A0

http://dj8wx-dl.de/hompage500kHz/TX%20equipment.htm

=A0

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=A0 500m.

=A0

I tried a measuring of the current between=A0 the footpoint of th= e matching coils and the radials:

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

=A0

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

=A0

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

inductivity: 245mH.

=A0

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

=A0

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:=A0 One couldnt touch any garde= n 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.

=A0

Best regards

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

Betreff: LF: Who is transmitting on 8970.022 Hz??


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.

73, Stefan/DK7FC
