My widest filter is 2.8. I am allowed to widen the DSP to 4. So why
not in AM, for BC receiving, be allowed wide enough for high fidelity,
without a roofing (or xmit) filter? (AM can be widened to "10", but it
sounds narrow and muffled)
I get much better bandwidth (fidelity) now using SSB to receive AMl,
but it makes noisy band-browsing because of all the heterodyne noise.

How can you have an IF bandwidth wider than 6KHz without using a
filter
that's wider than 6KHz?
