To bring it back to amateur radio, I found FCC publication OET65b fairly
straightforward. No need to exercise what I learned in the fields & waves class
I took in college (got a C+, I think).
I expect the program is handy, but it is Windows-only, so I can’t use it. But
the FCC worksheet can be

I strongly disagree. The heating effect - which is the only scientifically
verifiable effect from RF exposure - is far smaller at HF than radar
frequencies. Yes, you don't look into a horn antenna of an operating radar
transmitter, but a 20 meter dipole is a different story entirely. The exposur
I spent a good part of my career at Hughes Aircraft working on the Phoenix
Missile transmitter/receiver unit. Being an RF guy I was asked once to design

driven by an HP608 signal generator. The object was to drive a
