I've tried many times to get my head around the information needed to pass the Extra test and it's just not sinking in.

Most of it, in my opinon, is not stuff I need to remember because I can just look it up when I need to know something.

What is the effective radiated power relative to a dipole of a repeater station with 150 watts transmitter power output, 2 dB feed line loss, 2.2 dB duplexer loss, and 7 dBd antenna gain?

eh?

Why would I even want to remember the formula to calculate this when I can just go look it up?

Now, I'm going to go look up the airspeed velocity of an unlaiden European swallow.
