Indeed I am! I'm also adding ripple to the passband, decreasing the ultimate
rejection and adding ringing to the filter skirts. In short, it's a DSP way to
make the passband look more like the physically realized filters that we use in
analog rigs. My point was has anyone else tried this and did it sound more
"analog" to them when they did.
I know that analog AGC will also make a big difference to the rx sound and
there's probably nothing we can do about that aspect to make the AGC cat more
like an analog AGC (with all its attendant shortfalls), though I tend to like
my AGC to have a relatively slow recovery for anything but serious contesting
or DXing.
I guess this addresses how malleable our DSP is within our radios: can we use
the DSP to simulate or emulate an analog radio? Like a virtual OS, can be make
a virtual analog radio?

You're broadening the filter slopes by decreasing taps.
