With mine on 80m I have to reduce power to < 11 watts to tune either antenna (zepp/80m inv-l) in the CW section of the band. If I don't the tuner goes crazy and somtimes turns itself back to CALP or the leds start acting weird or it looks like it has tuned, but it once you tx at full power the swr is full scale. On 80m phone I don't have these issue. On 160m it tunes the zepp no problem.
