Hello Marco and Eddie,

The problem is solved. Thanks to Herbert, DG3MDE who showed me what was wrong.

Internet Explorer seems to ignore the mistake and displays the site correctly anyway.

I changed the html document now. So now it should work on all browsers.

BTW the sensitivity of this grabber is still poor. In many spectrograms, the noise background is still given by the soundcard noise. I have to build a preamp soon. However the location for the 2 loops is far from ideal. So it will be mostly a monitor for strong signals, such as sferics and local tests.
BTW local tests: Marco, the transmission is still going on! I am in Darmstadt for some days and the small VLF generator generates very little power on the fixed antenna, just in the range of a few uW, probably close to 1 uW. But i will QRO soon.Anyway, don't hestiate to try to receive something.
In a few days i will change to real DFCW-60000 / 47 uHz.

Now the 2nd experimental grabber should work as a reference, displaying my local test.

HiStefan

I did see your second Grabber when you first put put the multi colour on it but every time since you have a nice page but no captures. I am running Firefox, just tried the link again, those new visitors have not necessarily seen more than me you know, they could be disappointed visitors like me. :-)

Where are these .jpg stored ?<

All I see are 9 square bullet holes.

When ever I look at your second Grabber it is dead, like NOW, so I didn't look to compare, and I was in the garden planting out so as to catch this lovely Bank Holiday rain.:-)

Odd. Here it works all the time. Don't know what the problem is. Are you using Firefox or Internet Explorer? I'm using Internet Explorer and it works without a problem. Try again http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html

The last new visitor is from Italy so it seems to work for others too. 10 visitors yesterday...
