Hi to all,

only a question to the = experts:

is the=20 SLOW WSPR better than the simple OPERA-32 ???

For those who still try without success, here is = my=20 description in simple words.

If your RX is a HF TRX at 136 kHz = dial=20 setting, then the tone of DF6NM appears at 1440 Hz, the tone of DK7FC = appears=20 at 1430 Hz.

The microphone input is used and it must be defined = as the=20 standard audio input device. This is important since the SounInput = program=20 related always to the default input.

Then soundinput generates = the=20 audio file and replays it in SoundOutput.

SoundOutput replays = it to the=20 standard audio output device, which is the virtual audio cable 1 for = me. So=20 VAC1 must be defined as the standard output device!

The sound = input of=20 the WSPR software must be set to VAC1 too.

The file = wspr-8_rx.bat must=20 be edited. If the BFO frequency in the WSPR software is 1500 Hz, then = this=20 value must be inserted for fc in the row for the soundoutput=20 settings.

Set the value for fc for soundinput (the row below) = to 1450=20 Hz and save the file.

Then double click wspr-8_rx.bat and wait = some=20 minutes. You may watch the small souninput and soundoutput=20 windows...

Hope it works for others as well now.
