Default Sr. Citizen Question Re IF BW Settings

Hello,

I'm mainly a sw listener, Sr. Citizen now, and frankly not very
knowledgeable about radio theory.

Have a new WinRadio receiver that I'm enjoying very much.

But I realize there are several optional settings that I really don't
understand, and don't have a handle on.

I do listening from about 1 MHz up thru the vhf/uhf scanner freq's,
including MIL and Maritime stuff on SSB.

Regarding the IF Bandwidth options:

Might someone please give me a short discourse on what this does, and
what it effects.

And, some suggested (Default) settings that I could get started with for:

AM
NFM
LSB
USB

Also the effect of slow, medium and fast for what I think is
the the AF Filter

Thank you very much; appreciate the help,
Bob


BTW, slow/medium/fast is probably for the AGC (automatic gain
control). This helps to make listening comfortable when you switch
between tuning and listening, or with varying degrees of fading. Fast
AGC for tuning and slow for listening usually works well; and if the
fading is strong or rapid, your ability to adjust the AGC may help.
AGC often works well in conjunction with the RF Gain control - at
times of fading, pulling back the RF gain with AGC properly adjusted
can reduce the effects noticeably. In fact, without the AGC the
fluttering of the signal might drive you nuts! :-) Experiment and see
what works best for you.
