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
4 KHz or wider
NFM
use for 2-way radios, cops, etc. Use WFM for entertainment radio and
analog TV audio.
LSB
3 KHz or less for HF phone (mainly hams below 10 MHz)
USB
3 KHz or less for most HF phone (other than hams below 10 MHz)

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

AGC rates. Fast for knob-tuning. Medium for SSB. Slow for AM program
listening.

Thank you very much; appreciate the help,
Bob
