+<p>FmRadioReceiver is a sample application that demonstrates the use of the
+<a href="../../../reference/android/fm/FmReceiver.html">android.fm.FmReceiver</a>
+class to implement a FM Radio receiver in an application. The application allows the
+user to tune to any local radio stations, switch between them, scan for new stations and
+mute the radio. It also allows the user to change the radio band to their suit their location.
+The use of listeners is shown to display the tuned station name if RDS data is present.</p>
+
+<p>The FmRadioReceiver.java file in FmRadioReceiver also illustrates the interaction with
+the MediaPlayer. </p>

+<p>FmRadioTransmitter is a sample application that demonstrates the use of the
+<a href="../../../reference/android/fm/FmTransmitter.html">android.fm.FmTransmitter</a>
+class to implement a FM Radio transmitter in an application. The application allows the
+user to scan the 88MHz-90MHz frequency region for the channel with the least signal
+interference. The application then transmits any audio using the FM Radio chip.</p>
+
+<p>The suggested use is to start a long media file in the MediaPlayer application
+then turn on the FmRadioTransmitter sample application.</p>
