Hi Markus, LF,

It works! First reception of DF6NM in WSPR-8 here.

Timestamp Call MHz SNR Drift Grid Pwr Reporter RGrid km az

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.

73, Stefan7DK7FC
