Yeah, I know. It's an old thread. However, for $18 plus tax I picked up a little AM/FM/SW that I took on vacation. It worked fine.
It really does well on AM...which surprised me. The shortwave is only AM and operates only from 4.75-23.80MHz. So it's not a general coverage receiver and does not receive single sideband which you would want for listening to Hams on the radio.
But for $18 from Amazon...it's dang hard to beat. I like that it has both scanning and setting frequencies which is good...but you can tune with a dial and see the frequency digitally. Not a bad trick and especially not at this price.
It's small enough to pack around anywhere and cheap enough that you don't worry about losing or breaking it.
