Query: Finally a practical RF book

There is so much information for a practicing engineer;it will take six months to absorb the techniques described. I finally understand what causes oscillation and how I can prevent it when it shows up unexpectedly.I also appreciate that the math is minimized to the necessary level, without lots of proofs and derivations (I had enough of that in college). What I expected--and got--are techniques I can use in my work immediately.
