MOS training prep

[keith]

Any 18Es have any books, courses, or other training aids that they recommend for getting a head start on the 18E program?

I know computers like the back of my hand, and I'm really comfortable with ethernet based wired communications.

I'm more interested in expanding my knowledge of radio and satellite communications so that I'm a more attractive and knowledgable candidate for 18E. Plus, I can never know how much.
