I live in a valley in mountainous north central Idaho. I would like to buy a radio to be able to keep up with what is happening in this crazy world. I am thinking that rather than getting a wide band radio that I would not be able to use all of, I should get an AM/SW radio with good reception quality. Does this make sense and does anyone have any suggestions. For in home use. Battery powered. Under $500. range. Thanks for any suggestions/help.
