Hi Terry,
 
excellent!
 
Your SpecLab screenshot caused some head scratching... Stefans transmission from 15 to 15:30 was decoded and is visible in the WSPR waterfall. But then, this same one is also visible within the blue noise band in SpecLab, but only for half a minute ??
 
Finally the penny dropped: That must have been the 14:00-14:09 transmission which got trapped by the watchdog, and SpecLab timestamps are an hour off. Actually I had that same problem a while ago, with a newer version of SpecLab that automatically asks Windows for UTC, and I still had the local timezone offset engaged.
 
Unfortunately I didn't manage to decode Stefan in -32 here yet. Might have had a problem with my own transmission overloading WSPR outside the receive band. 
 
Best 73,
Markus

Screen grab showing decodes of FC and NM in WSPR32. I have now the correct  “Dial” offset to report the correct QRG. But spots not showing on WSPRNet which is running again. Is there a “filter” in WSPR2.11 which reads the dial QRG and, if not in an amateur band, does not upload?

Markus, i would agree to move to WSPR-32 now. Same QRG. Will be interesting to see the new spectrograms and the possible distances!


Stefan

Assume that you and Markus will be operational in WSPR-32 during the overnight as well? If you can, please TX running until shortly after your sunrise.

CFM, i will run the TX until 6 UTC in WSPR-32 mode on 136.164 kHz. My part is the first 30 minutes of each hour. This can be nicely seen on the grabbers, http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_LF_DX_Grabber.html ;arkus starts to transmit right after i have finished my last transmission.

An hour ago there was a very exciting funny race for me. I had to modify the watchdog circuit to allow a longer transmit time. This had to be finished before the next full hour starts. I took a micro-switch on the board and increased the R likewise from 560 k to 560+1500k Ohm. Soldering, drilling holes, connect 7 RG174 signal cables and the power supply, setting up the PC to generate the signal, giving power to the PA, all in 15 minutes ;-) I won the race but there was a bug anyway, somehow. Thus the time constant still was at 9 minutes and so my first attempt was negative. But the seconds was a nice success, as reported by Terry.

73, Stefan/DK7FC
