[SBE] Is it worth me pursuing my amateur extra license?

[A9xw at cs.com]

My Extra include smith chart questions and resonant circuit questions, 
about the same as my 1st phone element 3 in 1969. Element 4 then had a tube 
circuit and a transistor circuit and you had to figure out current and voltage 
values.  The radar endorsement you had to ID the various parts in a radar 
system, chokes, rotating joints, etc. I remember a question on suisoidal 
modulation, phase and "true" FM. 
I don't recall any AM phasor or tower patterns except one 2 tower pick the 
right pattern, fed 180 out of phase spaced 90 degrees and equal base 
currents. The Extra class license did give you code credit for one of the Radio 
Telegraph license levels. not sure if theyeven issue those anymore. A 2nd class 
was paper only and a first class required ship board experience if I recall 
correctly.
