only a question to the = experts:

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

I have used a virtual = audio=20 cable, with success.


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

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

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

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

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

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

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

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

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

Hope it=20 works for others as well now.
