The ICOM R-71A is excellent but pricey. However I've found success with

Old 1970s car radios are in general extremely sensitive. Selectivity is
sort of doubtful on a lot of them, but because they are normally used with
a small whip antenna, high sensitivity is essential. A Delco AM radio
should be available for free at your local junkyard.
