Note that all portable multiband radios will have an antenna optimized for 87-108MHz. If you want to receive shortwave better you'll need to add a couple dozen feet of wire to the antenna: https://en.wikipedia.org/wiki/Shortwave_broadband_antenna
couple alligator clips and a slinky toy will do in a pinch. although it is possible to construct a jam-proof and noise-reducing antenna for shortwave with a few strips of aluminum foil and some paper or wax paper (ideally). It lays flat on a floor or bed, and you "tune" it by moving the "frame" shape closer or further apart. there's a book involved.
