ULF,

After 9 hours of work the carrier is now back since 01:00 UTC. I'm now 
running the actual target level of *56 mA*, so the signal should be 6.3 
dB stronger now.
Eventually i'll have to do some worke work tomorrow but maybe not.
The carrier will stay on the air for a few days without interruptions if 
all works well!

Reports welcome :-)

73, Stefan

PS: Forgot to send the message last night (morning actually), must have 
been tired ;-)

Hello ULF friends,<br>
  <br>
I just opened up a new band by starting some activity on <u><b>1570 Hz</b>
  </u>! It is the <b><u>191 km</u></b> band! :-)<br>
  <br>
Since 8 UTC a carrier is running at 1570.01 Hz. Soon the first trace
will appear on a spectrogram from my tree which is in 3.5 km distance
from the transmitter.<br>

The carrier will stay on the air for 2.5 hours. It is just a first

DL0AO is already watching the band. I hope to be received by Paul and

on that band, just focusing on these 3 RX stations.<br>
