First decodes using 8-minute WSPR:

Between 23:36 and 23:43:20, Stefan was transmitting 8-times slow WSPR with low power on 136172 Hz. This was recorded here to an IQ file using SndInput from DL4YHF, and replayed 8x fast during the next 2-minute slot, starting 23:44. In the process the audio was frequency shifted from 670 to 2000 Hz, and added to the normal audio data for WSPR.  Thus with the 4x acceleration, Stefan's transmission appeared 8 instead of 2 Hz above center.
 
This is all still a bit improvised, but the concept seems to work.
