What you described is correct. However, a magnetic loop or other narrow-band antenna that needs to be tuned to frequency should be run without an auto-tuner in the transmitter. When an auto-tuner is engaged it is nearly impossible to tune the loop correctly to resonance resulting in troublesome matches that can stress both the loop antenna and tuner components. I use magnetic loops with other transceivers that allow the tuner to be disabled, but not with a K2. My K2 is used with numerous wire dipoles, full-sized loops, an LPDA, and verticals, but not with magnetic loops. Gus Hansen Email: [EMAIL PROTECTED] .....................
