With roofing filters, 250Hz filters, DSP, etc. I think it is
possible to totally lose situational awareness of the band.
What you, in your expensive high-tech bubble, think is a
clear run frequency, may actually be terrible, with loud
stations only 200 hz on both sides. Many S&P'ers are going
to tune right by you, because it appears to be an
undecipherable mishmash. If a run frequency doesn't sound
good with a pair of 500 Hz filters, it is probably not a
good frequency.
