Hi VLF

Grande Stefan !!!!

Unfortunately have just read your email. This is amazing. I have just set m=
y last window at my grabber
to try 17.4701 KHz https://ea5dom.ure.es/grabber/index.html

Thoght that this Christmas we would have no SAQ, but then you fixed that ! =

Hi VLF,

Since 23 UTC a 700 mA carrier is running on 17.4701 kHz!

It is a little surprise to the VLF community i think ;-)

Legal? Yes: http://www.iup.uni-heidelberg.de/schaefer_vlf/VLF/17,47kHz_Sond=
erlizenz.jpg
Actually the document has 3 pages but the other ones are no so relevant.
My ERP is limited to 5 mW. I did not request more because more isn't possib=
le anyway with this antenna.

I wound a big single layer coil with 0.5 mm enameled wire on a PVC tube wit=
h 315 mm outher diameter.

0.7 A is just a first careful step. The coil is designed to hold 1.5 A 'key=
 down'.

The carrier will run the whole night and even tomorrow at daytime.

Worldwide reports are welcome ;-)

It is not sub-9-kHz but still VLF, the 17 km band!! So give it chance :-)

The tree has still some solar power to stream the signal from the EW loop d=
own to the city, so there is a feedback spectrogram at
http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html


73, Stefan

PS: I still can hear that tone of the coil. It is terrible! Be happy when y=
ou are older than me!
