Betreff: ULF: 5 characer message detection = at 970 Hz

Hi ULF friends,

Last morning i transmitted a 5 = character EbNaut message on the 309 km band.
At 970.1 Hz i run 1.7 A antenna current into my 900 m = spaced earth
electrode a= ntenna. The transmission took about 3 hours.
The DC resistance was quite high this time, about 93 O= hm. Anyway i got
about t= he same antenna current when running about 300 W.
The QRN/QRM was low and just a few days ago i adde= d a shutdown option to
m= y solar charger. The Raspi can turn it off by switching a GPIO Pin, so
the off-time can be defined = into a script which is executed on the day
when the transmissions happens...

Best results were obtained from the E fied on its own! I got an SNR &= gt; 17
dB! See the attac= hment for details. The message is important these days.
It should be copied by a lot more people.

This is the first far field message detection belo= w 1 kHz
generated/receiv= ed by amateurs.

QRB, as usual, 57.6 km.

73, Stefan

PS: It was a gr= eat sunny autumn day, just like today.
