Here the results are looking most promising as well. Sri for the non decodes of DF6NM. But maybe in the next test! The SNR levels are very high. I would like to evaluate the effect of sferic blanking to the WSPR signals and its performance. If sferic balnking, done in SpecLab, improves the WSPR performance significantly, then this may be important for Joe and the new JT8 mode which is intended for MF/LF where QRN is much more dominant and aggressive than on 20m or so. For the next test i suggest to use WSPR-8 again, on the same QRG. I shall reduce the power level by 20 dB. Then Terry, i would like to have an audio recording, a wav file generated in SpecLab. If possible, my signal should be in the center of a SSB filter bandwidth (or wider), directly coming from the soundcard. Timing is critical again. You must start the recording exactly when my transmission begins and it must be stopped after exactly 8 minutes! Then you can pass me the file in Dropbox. I will then replay the file in SpecLab, in an endless loop. First i will use the file as it is, to confirm the decoding works and the decode levels are always the same. Then, i will add a 2.5 kHz bandpass and apply sferic blanking by using the SL noise blanker. In QRSS/DFCW this makes a subjective improvement of 6...10 dB, depending on the noise levels. If we can get another 6 dB by that, then is assume that W1VD will successfully decode DF6NM, which would be a nice confirmation. Jay, the DST levels according to http://lasp.colorado.edu/space_weather/dsttemerin/dsttemerin.html must have been very good for transatlantik LF work, right? Jay, would you like to try run the WSPR (including the add-on tools from Markus) "behind" the band filter and NB that you're using to display the EU60 band on your grabber tonite? First i have a "onw-way-sked" with Martin and also try to leave traces at http://icas.to/argo/eu.htm in QRSS-120. Conds are excellent! Later i would send some sequences in WSPR-8. For the recording and tests, it may anyway be better to use the typical night-QRN when the band is opened between Terry and me... Terry, OK? For testing and comparing night time QRN levels and daytime groundwave QRN/QRM levels and the difference of sferic blanking it may be even useful to have 2 recordings. Thus i will *NOW* start to run the TX in WSPR-8 with a 20 dB lower LF signal compared to the typical values. I'll run the beacon in 100% mode so that Terry or someone else can easily take the recording (if you like to participate in the test). The beacon runs until about 17 UTC, then i have to QSY to QRSS-120. 73, Stefan/DK7FC Am 24.09.2012 09:38, schrieb Terry GW0EZY: > > Stefan/Markus > > Full decode list as nothing was uploaded to WSPRNet (1530-1630 > adjusting dial QRG) > > UTC > > 1530 5 0.6 0.137987 0 DK7FC JN49 30 > > 1600 -6 0.2 0.136181 0 DF6NM JN59 27 > > 1630 6 0.2 0.136167 0 DK7FC JN49 30 > > 1700 -6 0.2 0.136165 0 DF6NM JN59 27 > > 1730 6 0.2 0.136164 0 DK7FC JN49 30 > > 1830 3 0.0 0.136163 0 DK7FC JN49 30 > > 1900 -7 0.0 0.136164 0 DF6NM JN59 27 > > 1930 1 0.1 0.136163 0 DK7FC JN49 30 > > 2030 2 0.1 0.136163 0 DK7FC JN49 30 > > 2100 -9 0.1 0.136164 0 DF6NM JN59 27 > > 2130 5 0.2 0.136163 0 DK7FC JN49 30 > > 2200 -9 0.3 0.136164 0 DF6NM JN59 27 > > 2230 2 0.1 0.136163 0 DK7FC JN49 30 > > 2300 -3 0.0 0.136164 0 DF6NM JN59 27 > > 2330 2 0.2 0.136163 0 DK7FC JN49 30 > > 0000 -5 0.1 0.136164 0 DF6NM JN59 27 > > 0030 3 0.1 0.136163 0 DK7FC JN49 30 > > 0100 -11 0.1 0.136164 0 DF6NM JN59 27 > > 0130 1 0.0 0.136162 0 DK7FC JN49 30 > > 0200 -6 0.0 0.136164 0 DF6NM JN59 27 > > 0230 4 0.1 0.136162 0 DK7FC JN49 30 > > 0300 -10 0.0 0.136164 0 DF6NM JN59 27 > > 0330 -2 0.1 0.136162 0 DK7FC JN49 30 > > 0400 -16 0.1 0.136163 0 DF6NM JN59 27 > > 0430 3 0.2 0.136162 0 DK7FC JN49 30 > > 0500 -9 0.2 0.136163 0 DF6NM JN59 27 > > 0530 4 0.3 0.136162 0 DK7FC JN49 30 > > 0600 -9 0.2 0.136163 0 DF6NM JN59 27 > > 73 Terry > Am 24.09.2012 13:24, schrieb jrusgrove@comcast.net: > Stefan > > Good T/A copy of your WSPR-32 transmission ... unfortunately no > reception of DF6NM.
