I have just fitted two option filters to my K3. I have FL1 FM, FL3 2.7 std, FL4 400Hz 8 pole.
Setting up the filters by mode I noted a strange effect. AM,FM and CW were as expected. On USB I set the filters available to FL1 and FL3. I was listening on 20m but each time I changed mode and back I ended up with FL1 slected and no ability to change it - That is until I also enabled FL3 for LSB. Once I had done that I could set the USB filter. Now I think I understand why this happened, USB is really using LSB above 10MHz MHz because of the 8MHz IF, but the dial says USB to avoid confusion. This feature may be by design but it is rather confusing.
