This thread was from a week or so ago, and I gave some bad info I want
to correct.
For Tom and anyone else using or thinking of the MFJ-998 auto tuner.
It turns out the mode button is only for getting into the setup menus.
To change between auto and semi-auto modes: Press both the "ant" and
"tune" buttons at the same time. Ant is top row leftmost, and tune is
top row rightmost buttons.
Single beep for auto mode and 2 beeps for semi-auto.
I don't use this setting very often, and don't know where I got the bum
info from. It seems that using the word "mode" to refer to both the
menus, and also to refer to the types of tuner operation is a bit much.
Sorry for the bad info. Hope nobody smoked any gear.
