Hello Marcus, Stefan,

 

very interesting.

Some WSPR-8 followed by WSPR-2 sequences during daytime would show if the gain is 6dB as one could expect.

That's it. Today i want to provide exactly such a test signal, i.e. WSPR-8 at 50% TX and WSPR-2 at 50% TX between the gap.
I will lower the TX power by 6 dB. This should be sufficient anyway :-)

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.
