Hi Wolf and others Just want to tell you that the "Correlogram" funktion works OK. To see the difference between pure noise and Schumann ... /Sven...
I do both periodic screen capture and periodic FFT export as part of my meteor reflection monitoring setup. Timestamps start the same on both when I start the...
Hi, I have to do a final project and I have to compute frequency and amplitude of a sample from a wav file. Can someone help me to do it in SpectrumLab?if you...
Greetings everyone, ... It depends on the sources modulation. The well known navy transmitters use minimum shift keying, and to plot their 'carrier phase' over...
I am running a late Beta version, using a nominal soundcard sample rate of 22050. The actual measured sample rate is 22200.056 - the system allows me to type...
Hi, I have a 9000D, Signalink USP and HRD with DM780. Signal link is connected from the packet port on the rear of the radio. I cannot get the program to read...
