Radio without the headset Is it possible to hear the radio without connecting the headset?

I know the headset acts as an antenna. 

However, it would be great if I can just put the phone on the coffee table and listen to the radio without being physically connected to it via a headset.

I am using Samsung Galaxy 2.
No. Your earphone is used as an antenna. But, If your phone has a built-in radio app, connect your earphone, open the app and turn loudspeaker.
