Estimated 15 °C in the sun... Like in heaven! See: https://www.dropbox.com/sh/7ek90nptdid00sv/AADzH49qyT-fXq6fmCXZsWWga?dl=0 I have completed the matching of the second loop now. So there are different signals beeing transferred via the stereo stream now. These are read in SpecLab here and generate separate spectrograms where the difference between both loops become visible, see http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_remote_Grabber.html As a test there are now WSPR uploads from each antenna. Instead of DK7FC/P i am now uploading spots from DK7FC/NW and DK7FC/NE, for each of the loops. This will be done for a few days, just to study the difference of SNR, watch phase variations, QSB on MF and so on. I still need to do a fine tuning of the loops, i.e. decouple them from each other. The angle between them is just roughly 90 deg and there is room for optimisations. It is a very first state of that system now. First coloured spectrograms will appear on the grabber site too, in a hour or so. 73, Stefan Am 27.12.2015 21:48, schrieb DK7FC: > Hi all, > > Just for the entertainment, here some new images from the tree. > Description contained in the file name... > > https://www.dropbox.com/sh/xe583ic42td6g37/AACCz_NNs0JZ_fm8BsYTZ1hCa?dl=0 > > There will be first colour RDF images on the grabber soon :-) > > 73, Stefan >
