I just purchased a FT-920 and I am having a little problem with the tuner. I my be expecting to much from it. I have a B&W 80-10 trapped dipole that the tuner will only tune 40, 20, and 10. Will not tune the WARC bands at all. When I use a LDG AT-MP on the same antenna with my IC-718 it will tuner all bands 80-10 meters. What am I doing wrong with the FT-920 tuner? Any help pse. 73 Gene N0MQ
