The manual ATU settings (called "LCSEt" in the KAT3 config menu) will not be remembered if you subsequently switch the KAT3 to Auto and hit ATU TUNE anywhere in the band. When you return to LCSEt the prevoius manual settings will be gone.
In the case of SWL bands, since they are just extensions of the ham bands in the K3's band mapping scheme you cannot expect a manual setting on the 19m SWBC band, for example, to remain if you subsequently use the KAT3 in auto mode somewhere else on 20 meters. Also, the manual settings are not remembered on a segment-by-segment basis as the Auto settings are. For example, if you set the ATU manually at the bottom of 160m that setting will apply at the top end and everywhere in between. There is only one manual setting for the entire band. It would be nice (but I suspect not widely requested) that the manual ATU settings would be remembered segment-by-segment as the Auto settings are, and that they would also survive an ATU TUNE in auto mode. For myself, I have found the manual settings useful on 160m where the KAT3 does not reach an optimum solution with my poor antenna. I can do better setting it manually. To set the ATU manually: Choose Config: KAT3 Turn VFOA until you see "LCSEt" Then push ATU TUNE. It will not transmit but will display the C and L values. You can then change them with the VFO knobs. You can toggle C between the antenna side and the tuner side by hitting ANT. You can also use the above to see what solution the auto tuner has arrived at. FWIW, a couple of feature requests that I thought might be nice to have: - K3 Utility option to display all of the currently stored antenna settings. - A firmware option to tune on received noise. 73, Drew AF2Z On Wed, 14 Nov 2012 13:16:09 -0800, Bill, AE6JV wrote: >You can use a manual tuner with an antenna analyser.
