These are the two radios I have that are capable of SW reception:

JVC PC100 boombox
Columbia Portable(model?)

The Columbia radio has screws on back for external antennas.. the JVC boombox doens't, but I guess that couldn't keep me from hooking something up with aligator clips on the built in antenna?

At the moment someone is borrowing the columbia to liston to really bad music(well, ok, I just don't like what they like) on some FM station while they work on their car in the garage.
