Spec An Radio
So, I’ve managed to coax my spectrum analyzer to play FM radio!
It’s actually fairly straight forward, attach an antenna, with some physics, I found that a 100M monopole is around three meters long. I soldered a piece of 22ish gauge wire to a SMA connector.
In the Aux Ctrl menu turn ON demodulation, and select FM. Use the marker to tune channels. Adjust the dwell time to change the FFT length. Really you should just have a look at the video.
