[R-390] Red Dot - Second try a charm (Maybe)

[Bob Camp]

Hi

I have always looked at it this way, it may not be right but it seems 
to work.

The whole idea of the antenna trimmer is to compensate for an antenna 
that may be either capacitive or inductive. When you do an alignment 
the trimmer capacitor should be half way meshed. That corresponds to 
the knob being straight up. I generaly lift the lid to see what the 
state of the cap is ....

	Take Care!
