Re: "... I don't know how to tell if those filters are on or not?"
If all you want to do is check to be sure they are being selected properly, skip down to the third paragraph below where it talks about FL1, FL2, and FL3. If you want to be sure they are turned on (enabled) in the menu, then keep reading: Press and hold the DISP (MENU) button until the menu shows up in the main display. Rotate the OFS/VFO B know B knob until RX XFIL show up in the display, then rotate the Main tuning knob to get the display to read NOR for normal operation (filter working) or NOT INST if the filter is not installed. Exit the menu by tapping the DISP button. The filters may now be working, but it may be necessary to power the KX3 down and back on to get them to work. The manual isn't real clear on that. If you bought your KX3 at the same time you bought your filter module, the filters should be installed and the required opposite sideband suppression calibration should have already been done, even if your KX3 was a kit. If not, you will need to do that calibration after enabling the filters. That procedure is in the KXFL3 Installation and Calibration Instructions which is available on the Elecraft website. Once you do that, as you narrow the bandpass down using PBT I/II knob, the XFIL display in the main display just above the PBT knob (NOT the menu display noted above) will move from FL1 to FL2 to FL3 as you narrow the BPT down. BTW, I don't believe the filters make a great deal of difference in what you hear on the radio unless there is a very strong signal just outside your current passband. Someone who has used the radio with, and without, the roofing filters can probably provide better experience than I can. I have never operated without the filters installed.
