past the Amateur Extra exam. Yahoo!!
This was hard studying for me so can't brag with "that was easy"
nevertheless, it is only when I studied for the extra that I started to understand better the whole radio technology.
the best way I can describe it is that for tech and general I studied "about" the concepts, but for the Extra I had to study and understat "the" concepts.
I recommend studying for the extra, but plan on spending significant amount of time.
For reference, I studied three weeks for the Extra, including in the last two weeks doing almost nothing but working studying and sleeping. but I am thick so it may be easier for most.
Got 47/50 so I am pleased
