[Mobile-Portable] Screwdriver antenna controller

I also have one of the ASAC (Am-Comm) controllers.  It seems to get 
confused a lot, especially moving between the high bands and the low bands 
(40/80).  As someone eluded to, it takes longer than 15-20 seconds to move 
around, requiring a second or third punch of the IC706 TUNE 
button.  Sometimes, when I punch the button it starts tuning the right 
direction, then the next punch it goes the opposite direction.

Worse, sometimes it gets confused enough that I don't even know where the 
thing is... like if I'm trying to get on 40 and it somehow doesn't stop 
there or went the wrong way, then I lose track of the thing and even I 
don't know what direction to go.  The usual cure is to pull over and look 
at the coil then guess where to go from there.

After using the ASAC for a few years, I would switch to a turn counter in a 
heartbeat.
