Hi
Stefan, Markus, EbNaut
Confirmed Markus. After changing the FFT export files setting to
"Complex (real+imaginary)"
it decodes perfectly :-)
I have learn a lot this days. Will be updating some help files
I'm preparing to help my memory
and others on this issue. Thanks again Markus and Stefan
Yes. Next step will be to transmit a message with the proper
antenna. But may be still without
Mosfet. Will be interesting to check what can I do with 100mW
and EbNaut. With 30W I got
many Opera32 decodes at Markus grabber

Hi Luis,
Time to connect a MOSFET to the MOSFET-driver!
73, Stefan
PS: Don't forget the LPF :-)

Hi
Stefan
The FFT lenght is 32768 and the exported FFT bins are
16384. Anyway the .usr file is attached
The signal is almost 20dB over noise at 5mHz bandwidth.
Clearly visible and I can also see the sidebands in other (faster)
instance
when modulating phase at 0.1 s rate. The power is very
small. Just what I can get from a MIC4452 mosfet driver at 12V and
the Tx antenna is just a 5cm piece of wire. The Rx
antenna at about 15m away in the roof
Transmitting from my QTH with the big antenna and same
power produces a similar S/N
But then we add the posibility of a timing offset to the
puzzle
