RF Spectrum Mod

@General Meatsauce For the frequency spectrum calculation : do you use FFT ? There are very efficient methods to implement it (DFT) .
What is most useful for spectrum analysis is the so called "online psd" which is a very efficient way to calculate the power spectral density of a given signal. I once implemented it myself, works great.

It is not a time-domain signal being transformed into frequency space. Each row is generated analytically: the receiver asks “what transmitters are in view?”, estimates their received power (via FSPL + LOS), and paints Gaussian “energy bumps” at their frequencies over the noise floor. Those rows are then stacked over time to look like a waterfall
