[TowerTalk] Force 12

I had a lot of trouble tuning 10m once with a C4XL (and changing element 
length was really bizarre - small changes act as expected, but at some 
point there would be a big jump to a wildly different resonance), they

THINK the problem is that the drive cell is really sensitive to spacing 
and parallelism between the elements.  If so, then it means loosening 
the U-bolts and shifting element position.
