How is the best way, other than finding another freq of course, to filter out someone on a nearby freq that is way overpowered and bleed onto all the freq around… Im sure there is a setting Im missing somewhere
HF, VHF or UHF?
If narrowing your roofing filter — and tightening your passband filter — is not enough, you can try using PBS (pass band shift) and the notch on the offending edge to block some of it. But the rude reality is, if by function of pure wattage, sloppy audio or physical proximity that doesn’t work, you are probably down to negotiating with the perpetrator.
A directional antenna with effective nulls can also help, but it’s a BandAid at best.
Notch Filter; since u have a 7300 like I do
Push the waterfall to get an expanded display of the frequencies
Push the top left button and use the filters ..look like square waves and dial around until you have effectively “notched ” out the offender
Also you can push the screen last 2 digits to get (after 5 seconds or so) a THIRD digit to give you more tighter tuning.
Enjoy

thanks to both. Defiantly prox. he is from MN. Just rude behavior IMHO. He was just saying CQ CQ CQ about 25 times then unkeying and doing it again, and again… Wouldnt be so bad but he was about .05 away from a POTA activation I was trying to work…
7300 also has a notch setting, I keep it on narrow sometimes wide but its always on… I use the 3 filters set to more specific settings that helps too.
When I had a pair of phased 2 meter beams, I used them to notch unwanted signals all the time.
