Mine works fine up to 2:1 on most bands, although on 160, it starts to get a little annoyed at that point. Pretty common for "no-tune" solid state amps. an > band width seems narrow . Don't know what you mean by this. My 160 antenna BW is pretty narrow [10 KHz], 80m is better [~50 KHz] but that has nothing to do with the KPA500, into the 1:1 dummy load, frequency doesn't matter. The SWR seen by the K3 looking into the KPA500 is 1:1 all over all the bands too. How have you handled this with you > antenna’s . Is anyone using a tuner I use some wires multi-band, so yes, I use a tuner, especially on 30, 40, 80, and 160. Haven't tried the antennas on 60m but probably will after 5 Mar since CW will be allowed then. Waiting with credit card "on warm" for the KAT500 announcement.
