[QUOTE="Analoguesat, post: 1159575, member: 176362"] What I found when I started playing with SD. I couldnt get the frequency plot to populate. SD was seeing the RTL-SDR & everything seemed to be ok but when I hit run nothing seemed to happen. Until on one occasion I happened to to restart SD & be watching the frequency plot just as I clicked start. The frequency plot appeared BUT it then rapidly sank right down till it was out of view off the bottom of the plot! After a bit of head scratching it turned out you change this in the FFT tab. These are the settings that are currently working here for me from top to bottom in the FFT tab FFT SIZE 1024 FFT RATE 50 WATERFALL RATE - waterfall not enabled - its too intensive for this processor & it bogs down FFT MAX -20.0 FFT MIN -87.8 - my noise floor is around -75dB AVG NUM 66.3 When I start SD now with these settings the frequency plot now appears at the top of the frequency screen & sinks down stopping in view at -75db [USER=275842]@pontiend[/USER] you can remove Meteor M2 if you dont have 1.7GHz antenna capability - the VHF is broken on that one. You also need to set the frequency in SCHEDULE & CONFIG like this [ATTACH type="full" alt="1710351782931.png"]154951[/ATTACH] also click on the little CONFIGURE tab to the right of LIVE & set the NOAA number for the NOAA birds. If you have a DC spike on the middle of the frequency you can ENABLE DC BLOCKING in the satellite CONFIGURE tab.
