Hello Markus, LF,

Thanks for watching and the note. Join in! It is the time now! Let's see 
how many we can become!
There is a surprising + impressing high activity, better than a few 
years ago when i went to MF/VLF. Reports by 24 stations in the last 12 
hours, far from what i have expected. Not so many Russian stations any 
more it seems. But late in the night i saw RUSWL and switched to 
WSPR-15, reached him a few times then. Maybe the beginning of a come 
back of a few more...
Oh, now i see there is G3XIZ as well. Looks like a spontaneous party!!!

I'm running 150V*0.8A DC input to my H bridge PA and a small lossy coil 
wound with 0.75mm^2 loudspeaker cable, giving about 3 A antenna current.
I'll build a phase shifter with a XOR gate into the exciter line, so we 
can also try some EbNaut. Maybe you can decode my signal over that distance.

73, Stefan

I see you are strong again on LF. I started my JT9 RX here on LF.
However the QRN rised extremely since the afternoon.<br>
  <br>
The latest versions only support JT9-1. This was successfully used by
several stations on MF some months ago. For LF, a frequency below
137.45 should be used, to avoid collisions with OP32, WSPR and EbNaut
transmitters. So just try <b>137.4 kHz</b>. I'm watching there for you
now. If your U3S does not support JT9-1, maybe there are firmware
updates?<br>
