[TenTec] ORION Display (horizontal line??)

[Richard Williams]

Allen,

The way I read Bernie's question, he is asking about the thicker solid line 
that is directly above the spectrum display.   There is a "break" (it 
becomes a thin line) in it just between the "0" and the next number (.6, 
1.2, 2.5, 5, or 10 - depending on the sweep range) to the left.

I read it this way because Bernie says:  "Immediately above the spectrum 
sweep scope is a horizontal line on which the rectangles representing the 
bandpasses for the main (left) and sub (right)  receivers rest".   The 
rectangles don't "rest" on the the horizontal line(s) above the filter 
bandwidth graphic; which you  correctly defined in your response.

Personally, I don't know what the break in the bar represents;  interesting 
question,  do you happen to know the answer?
