I have a question:

when we use Pavels' VNA application which jumper setting should we set at IN1 port ? The default setting is LV (LowVoltage). There is also the option to use HV (HighVoltage) or even jumper settings 2-5 to bypass the attenuator.

Should one use LV or 2-5 jumper setting to bypass the attenuator? What is best and suggested ?

The LV position should be OK.

I am wondering is it safe to use it with baypass. :idea:
I use RP as skimmer serwer with metal case, so open it every time when I need to use vna is difficult.
Or maybe I can change default VNA port for IN2 ?

It should be safe if you set Level to -12 or -18 dB. Adding an attenuator to OUT1 could be also a solution.
