If selectivity is of no concern you might find that connecting an antenna to the 'microphone' or audio input will allow a local AM station to come thru. If I am working on an amplifier and touch the input I'll hear the radio station that is about 2 miles from my house - 50,000 watt transmitter. Otherwise what you have is more or less the audio amplifier and earpiece - you'll need to come up with the rest of the radio.
