...i just checked the old emails. It was in 2012. Here is a link to 
Markus' website which contains the slowWSPR tools, 
http://df6nm.bplaced.net/wspr/ . It works for TXing and RXing. For TXing 
you can use the normal software of course. For RXing you can use the 
latest WSJT-X software set to WSPR-2. You need something like VAC to 
lead the audio to the input of WSJT-X.
It is some years ago that is used the software but there is a readme 
file. So maybe someone likes to try to use it.
Jay/W1VD may add instructions on how to set it up for RXing.
I hope the file comes through...

73, Stefan
