Re: RTL-820T2 IF filters / ISR reception

Yes, that is the first thing to do.
Front end filtering can improve even the best receivers.

Re: RTL-820T2 IF filters / ISR reception

Having looked a bit further I find https://www.rtl-sdr.com/new-rtl-sdr-dri ... r-console/ which appears to suggest that in the presence of strong out-of-band signals performance may be improved.

Re: Multipsk not seeing my rtl-sdr dongle, why?

Look at the help for your virtual audio.
They have a repeater function if you find it.

Re: RTL-SDR.COM ceased working since Update from Microsoft

The usual thing is that Microsoft replaces the SDR driver with a TV driver..
Use Zadig again.

Re: need help about RTL2832U

You will need a BPF filter if you use a direct sampling dongle.
Like 3.2 Narrow Band Pass Filter here https://www.irjet.net/archives/V5/i3/IRJET-V5I3705.pdf
Probably a good idea for any cheap radio.

Re: Filter and lna

Neither seems correct.
antenna -> Lna ->bandstop filter -> dongle ->USB PC is recommended.

antenna ->bandstop filter -> Lna ->dongle ->USB PC might be required if the LNA is not a good one.

Re: RTL-SDR frequency step/accuracy

100Hz steps for a digital television tuner seems overkill.
Is it is a limitation of the device itself?
