+#X text 38 27 the "fft analysis" window here simply divides each complex bin of the FFT by its own magnitude to "flatten" the spectrum. The "squelch" control limits the amplitude boost the algorithm will apply. If infinite \, you'll get a white spectrum \; if less \, the louder parts of the spectrum will be flattened but the quieter ones will only be boosetd by the squelch value.;
