Tnx Gary and the group for that excellent discussion!=20
=20
Maybe, if you are involved in that VLF group, you can give them a hint wha=
t is happening here in the last days ;-))
I rather will spend my time for setting up that vertical TX antenna on 8,9=
kHz... I will start in 30min, driving to my parents, where my "electronic-=
lab" is ;-) Building that PA, tmw getting and testing and resonating that=
 coil. Testing the PA at the coil (if there are HV and heating problems).=
 Perhaps, if everything, including the wind, will be right, i will try a=
 transmission on sunday morning but that is still uncertain and i would te=
ll it to the group before.
I wrote a mail to some Lowfers in my region if it's possible to RX there.=
 Bernd/DF8ZR is just abt 16km away from my /p QTH and well equipped on low=
 frequencies. Marco/DD7PC is abt 45km away...

Hi Stefan, LF,=20

There is a VLF Group at the following :-=20

http://tech.groups.yahoo.com/group/VLF_Group/

<http://tech.groups.yahoo.com/group/VLF_Group/> The members discuss & are=
 involved in a different field of VLF, mainly in "natural radio"

Have a look at some of the discussions, it is an interesting & informative=
 group.

73, Gary - G4WGT.

    Which commercial VLF transmitters can actually be received in the 10kH=
z range? There is much listed in the web but in times where these transmit=
ters are shut down all this may be already old stuff. Who is receiving in=
 this frequency region and can tell us a frequency and the SNR he is achie=
ving? There are so many OMs who watch the VLF sector and have nothing done=
 with LF and this group. Perhaps it it an idea to activate/motivate them=
 for some tests, to increase the RXers density.
    Maybe it is good to compare some RX rprts in that region. But i will=
 rather be active at the transmitters front now ;-)
