Well... shoot, Jerry.    Now I AM confused.   I spoke with Paul
Hrivnak and company at Dayton last Friday and that is what they
told me to do... but now you are giving me somewhat different
instructions.   So... now I all conflicted...

Is this reason to get a beer?

Is there some way to reconcile the two methods?

If so... is THAT reason to get a beer?

Is it reason enough to get the TT tuner instead of the Palstar?  or to 
justify getting the Palstar auto tuner (which I think I want) because it 
may work more like the TT tuner, and also be automatic for "just" a few 
hundred more?
