It's your direction from the facility, not your heading. In your example, if
your position is in the 192-degree wide segment from northwest through
southeast (roughly), use 123.75; if your position is in the segment left
over, use 119.9

I can never get this right!
When the airport list's it's approach freq like this
123.75 (320-152)
119.9 (153-319)

does that mean that I should call 123.75 if my heading is between 320 and
152 or the opposite?
