Hi all,
 
its no longer a secret :
Stefan and Markus found a carrier at 8970,022Hz on Stefans and= Gerhards 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 visibili= ty of the carrier on Gerhards grabber.
 
My aerial: pse see
 
 
second last pic on the site. The 23m long wire has been lengthe= ned by an other 20m.
The radiasls have a overall length of&nbs= p; 500m.
 
I tried a measuring of the current betwee= n  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 13= 4uH (Z 7,5 Ohm).
 
The diameter of the circuit single layer winding coils: on aver= age 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= garden hand tools or other things longer than 50cm.
Txing with 750W: My XYL doesnt shriek any more when working in= the 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.
