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 ;-)
Actually the document has 3 pages but the other ones are no so
My ERP is limited to 5 mW. I did not request more because more isn't
possible anyway with this antenna.
I wound a big single layer coil with 0.5 mm enameled wire on a PVC tube
with 315 mm outher diameter.
0.7 A is just a first careful step. The coil is designed to hold 1.5 A
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 down to the city, so there is a feedback spectrogram at
PS: I still can hear that tone of the coil. It is terrible! Be happy
when you are older than me!
