It helps. I have all I need in the posts you typed earlier and much appreciated, thanks. In fact I always find your posts helpful.
A book such as ARRL I think is middle level technical. You don't find formulae or calculus. Just maths and square roots and ratios. It's now my favourite reference book but maybe not many people use it as it's Americanised, and geared to HAM. It's very big on graphs and I like the way they throw in a couple of questions to consolidate each point. The FM section is pretty thorough for a book that age but some points needed padding out a bit.
