Yes, I could do those things.  And sometimes I get a little carried away in
aiming the antenna precisely at a station.  So I haven't bothered.

hmmm, shouldn't be hard to find a small chicken head knob and put sticky 
dots, or a dab of glue that will harden into a dot at the east and west 
points on the pannel behind the knob?
I'm sure you thought of that, but it might make it easier to get to those 
directions more quickly and with some greater certainty.
