Hi Stefan, LF,

I am not involved with the group, I joined only to read the interesting mails & discussions & do not get involved. Just the occasional response from me. I know that some members also subscribe here to LF.

You could subscribe yourself & I am sure you would be made very welcome & share experiences with the other members. I have seen that they are very helpful to each other.

I can receive down to about 5kHz or so with my transverter (performance not measured) & lower with sound card receivers & I do occasionally tune down & look/listen.

Good Luck with your project es 73,

Gary - G4WGT.

Tnx Gary and the group for that excellent discussion!

Maybe, if you are involved in that VLF group, you can give them a hint what is happening here in the last days ;-))
I rather will spend my time for setting up that vertical TX antenna on 8,9kHz... 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 tell 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...

73, Stefan/DK7FC

Hi Stefan, LF,

There is a VLF Group at the following :-

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 10kHz range? There is much listed in the web but in times where these transmitters 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 achieving? 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 ;-)

       Stefan/DK7FC
