Hello Jurgen, Just a thought... try to switch the various attenuator settings (in the Perseus sdr control panel) in and out, and watch the amplitudes (magnitudes) of all those peaks. When stepping th
Here the following 6h spans of today Should be interesting to some of you despite the discovered aliases The 9-10h section suffered a loose antenna connection http://dx.3sdesign.de/temp/Spectr-110126
I refer you to a previous msg of mine a few days ago about Images. Looking at a broad band spectrum one cannot distinguish between genuine signals and IMAGES. I described how to distinguish the genui
Hi Jurgen, Receiver kaputt? Please compare 16-26 by 36-46 kHz in that plot. Additionally there are some signals visible above 50 kHz never been observed by others. Gruss aus Kiel, Peter
Hi again Jurgen, It's a "ghost" of MSF, 60 kHz, which is incredible strong over there. All other signals appear twice in your plot shifted by +20 kHz. I don't know what happend since I do not know (i
Last night I started SpecLab to plot 10-72 kHz Here is the result until 0800 local ( = 0700 ut) http://dx.3sdesign.de/temp/Spectr-110126-0800_10-72kHz.jpg The same but zooomed http://dx.3sdesign.de/t
Hi Peter, Thank you very much for pointing that out ! I didn't realize it myself, was too busy with other things Something must be wrong with SpecLab when it uses Perseus h/w directly. I already repo
