That is OmniRig that makes that selection to FIL2, you could edit the OmniRig IC-7300-DATA.ini to select another or just go with it. Personally for the 500Hz VARA HF mode I set my filters to 600Hz to reduce QRM. I would do 500Hz but there are numerous stations that are not using super accurate radios and 600Hz give me some room for VAFA HF to do its AFC magic.
Gary, You are right, I think I am missing some data with that narrow filter on. I have made some changes to the 7300, think it will work better hi , 73 Gary

Personally on the 7300 I kept it as is, but when I had a TS-890 I created a ini file so that it worked as I wanted it to.
