hi,
"simple" =
- modulation ON-OFF , no needs for linear P.A.
- no precise timing (= little beacons stand_alone. no PC.)
- TX only 50% on. (to take in mind when compare whith other
"continous" mode at parity of output power.)
- the coding scheme is more robust than WSPR.

-32
Hi to all,
only a question to the experts:
is the SLOW WSPR better than the simple OPERA-32 ???

Hi Markus, LF,
It works! First reception of DF6NM in WSPR-8 here.

I have used a virtual audio cable, with success.
For those who still try without success, here is my description in simple
words.
If your RX is a HF TRX at 136 kHz dial setting, then the tone of DF6NM
appears at 1440 Hz, the tone of DK7FC appears at 1430 Hz.
The microphone input is used and it must be defined as the standard audio
input device. This is important since the SounInput program related
always to the default input.
Then soundinput generates the audio file and replays it in
SoundOutput.
SoundOutput replays it to the standard audio output device, which is the
virtual audio cable 1 for me. So VAC1 must be defined as the standard
output device!
The sound input of the WSPR software must be set to VAC1 too.
The file wspr-8_rx.bat must be edited. If the BFO frequency in the WSPR
software is 1500 Hz, then this value must be inserted for fc in the row
for the soundoutput settings.
Set the value for fc for soundinput (the row below) to 1450 Hz and save
the file.
Then double click wspr-8_rx.bat and wait some minutes. You may watch the
small souninput and soundoutput windows...
Hope it works for others as well now.
