I just got a book from the library yesterday, Titled, "Electronics, the easy way." It has a bit about radios and antennas in it, but also gets back to basics of ohms, volts, impedance and stuff like that which, if youre like me, you have no idea about. This becomes a serious set of brakes when one is trying to become an amateur radio astronomer.
Time to start reading up and educate myself.
