Hi Terry,
 
the setup for wspr-32_rx is identical to -8, and the same fc edits would have to be made. Yes you can split accelerated slow WSPR from incoming normal WSPR. Using audio routing options a (two soundcards and analog cable) or c (VAC) will intrinsically do that. With option b (analog loopback through mixer) it depends on the choice of frequencies. I have now been using fc = 3000 Hz from SndOutpt to WSPR, which is well out of the passband of the SSB RX, so WSPR sees only the converted audio.
 
If you like I will start a WSPR-32 transmission this afternoon, using odd half hours and 136160 Hz RF (ie. 4 Hz below Stefan's current WSPR-8). As my antenna can only operate in fair weather I'm not sure how long I will be able to transmit tonight.  
 
Best 73,
Markus (DF6NM)

Hi Markus

 

Thanks for the opportunity to participate in the experiment! I finally managed to get it working with spots sent to WSPRnet with your correct frequency. Unfortunately, I see I am also decoding “normal” WSPR because both audio streams are seen by WSPR. Is it possible to separate?

 

As you have distributed the WSPR32 file I would like to try. Other than running the bat is there any difference in the set-up?

 

 

73 Terry

Thanks very much Jay, Terry and Chris for taking the effort to receive and report our experiment, and of course to Stefan for suggesting it in the first place. I think the expected gain in sensitivity is evident, even though there is no "miracle machine" of course. I have now ended the WSPR-8 transmission from Nuernberg for today.

 

How would you like to proceed from here? Try WSPR-32 next? Perhaps a slow WSPR experiment on MF? Or wait for Joe's 8-FSK mode JT8 which might knock off another dB?

 

BTW I don't use a transverter for MF, but an FE-5680A Rubidium synthesizer which can be controlled to generate WSPR directly.

 

Best wishes, and have a nice Sunday,

Markus (DF6NM)
