There is a faint trace visible on the waterfall at the moment  0.122Hz bins, .  I guess you're in carrier mode.    During the transmission, there were occasional short lines there, corresponding presumably to runs of '1's or '0's

Successful decode of your callsign.

Hi Andy and thanks for tip of putting the diode across the gate of
the PA MOSFET in your posting a few months ago.  I'm using the class
E amp at the moment. The XOR can idle with high output so I decoupled it with a cap.

The symbols are 2 seconds.

Are these transmission using 1s or 2s symbols ?

Missed the 2000 sessin, but I'll record some of the later ones.

Markus Paul and Domenico, Group

I have new message 5 characters 512 symbols and hopefully corrected
the timing offset a bit.  Will start in 1 minute at 2000 utc
and on the half hour.
Running 50 watts tonight to get some lower Eb/No values.
Its just starting to get dark now.

Good day all,

here the results of my decodes. I have used the time offsets indicated by
Markus and Paul (thanks !)  to start searching the sequence. Signal is
very
weak here and there is no possibility to found a peak in his  squared
spectrum.


For last night, there are other positive  decodes under processing now.
Looking initial results, seems that transmitter has  worked with -3 dB at
least.
Is it true, Joe ?

Hopefully my low power tx will work and the bugs will not bite.

Starting 0000 UTC with same parameters as before.
