Well, I wouldn't say the tuner works everywhere. It won't tune some
antennas I've tried it on on 60 meters. The problem is that the tuner
doesn't switch for that band, it knows 80 meter band and the 40 meter
band, but not 60. It will tune, but it is much more of a problem on 60
meters. Another test you can do is as you tune across a band edge is to
listen to the noise and see when the filtering and tuner is switched.
If you move ten kc, over the boundary and you hear a relay click as
bandpass filters and tuners are changed and the noise drops
significantly, it is a good clue is isn't optimized for that frequency.
