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=20 appears at 1430 Hz.

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

Then=20 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 may=20 watch the small souninput and soundoutput windows...

Hope it = works=20 for others as well now.
