I have a simple Tecsun PL360 AM FM radio, measure about 60 mA at 4.2V with 3 1900 mAh Eneloop batteries in series So 1900 / 60 makes about 31.6 hours... With volume low. My big Tecsun PL600 AM / FM / SSB shortwave / mediumwave / longwave radio runs on 4 1900 mAh Eneloop cells and draws about 47 mA with backlight off. So that makes 1900 / 47 is about 40.4 hours. A month is a bit longer... But on AM medium wave you could use a crystal radio and that would last forever... I have some other small rechargeable FM radios from ebay, gave one away to somebody for her kids a while back. Maybe those use less power, but have a lot less battery capacity, last a few hours at most on a charge.
