Phil, If the SWR after a TUNE is not low enough for your tastes, just try doing it again, it often finds a better match. There is also the ALT setting which uses a more refined algorithm, but takes longer.
It may also be that the load is outside the range of the KAT2 on some bands - while the KAT2 has a wide matching range, it does have its limits. Very high impedance loads do give it difficulty. You can try adding or subtracting some feedline (1/8 wavelength at a time for the band having difficulty) to see if you can produce a better compromise antenna system input impedance. 73, Don W3FPR Phillip Heller wrote: > So I've completed the KAT2, so far so good. > > I get C55 to 003 +/- 2 (bounces back and forth).
