| HAM Radio Multimode Filter For Music?
So I've obtained some kind of HAM radio filter. It's clearly analog and it has multiple filter modes (lowpass, hipass, notch, peak). It has a limited frequency range (250-2500hz, and an "aux. notch" band reject that goes from 80-11000) but other than that, it sounds pretty rad. What I'm wondering is, can anyone point to some fundamental difference in the construction of a "musical" filter versus these radio hobbyist filters, or is the main thing just the frequency range?
