Re: LF: 4X1RF VLF Grabber on line

Hi Stefan,

 

Yes, I'm pretty exited also... Lots of sferics lately, been watching the live lightning map and looks like the Mediterranean area is quite active http://en.allmetsat.com/images/lightning-europe.php

 

Looking forward to your next kite test and hope for quite conditions.  

 

 

Thanks,

 

Chris

Chris,

Thanks for setting up this really promising looking grabber! Most time, the sferics are dominating the spectrum arround 6...9 kHz, not the mains hum. Thus i think you will have a good chance to receive something in the next test!
Tony/EI8JK received my signal in 1310 km at 15 dB S/N in 4.5 mHz. Your distance is not even twice that ;-)
So i will take the challenge in the next experiment!
Furthermore the grabber is in a quiete far location which will give us some ideas about different propagation on VLF :-)

So, CU soon!

Hello VLF enthusiasts,

I've been working for a while on this and I think it's time to publish my new on-line VLF grabber: http://www.qsl.net/4x1rf/vlf/vlfgrabber.htm

For now there are three displays, a 0-24Khz wide spectrum, one for the 33Km "dreamers band" and one for the 46Km band, refresh rate is set for 15 minutes.

I want to express my thanks to DK7FC for guidance and who's endless enthusiasm can be really addictive. Thanks Stefan and looking forward to your next kite experiment!
