Aw: LF: Re: new VLF-Activity on the next weekend

["Eike Katzera" <dl3ike@web.de>]

Hi everyone,

 

I´m glad to inform you, that our VLF PA is since 20min running.

We had some trouble with the  Y-capacitors in the switching power supplies. They didn´t like the 8970Hz and bourned up. We have now an alternative powersupply with conventional transformers.

 

We are driving now ~100Watts into erthelectrodes over a distance of ~250m.

The DC-loop resistance is ~30 ohms. 

TX frequency is 8970Hz.

We plan to increase the ouputpower in the evening. I´ll iform you then.

Hello Eike,

I went QSY with my 423 uH grabber window to 8970 Hz. (was 8270 Hz)

Looking forward to see your show :-)

Hello Group,

we are planing some VLF-activity at 8970Hz during a Meeting of  electronic hobbyists nearby  Kassel / Germany (JO40vr) on this Weekend.

The Plan is to run a VLF-PA between some ground electrodes. Due to other activities we have no exact time plan, when to start.

Depending on internet access i will inform you about the details.

Thanks for looking for our signal in advance.
