Dear OM vu3yda
Type this into a search engine:? ?ubitx bci filter
I see several useful hits. Ubitx.net shows designs using toroidal. I see a YouTube video describing a filter not needing toroidal, if you need that approach.?
This filter may need to go into receive path only, parts may not handle high power well or the loss could be too high for transmit.?
These large signals are overloading the receiver, while at the same time you may be able to tune in ssb and cw. Idea is to reject these lower frequency signals.?
