+/* Hamshield
+ * Example: Fox Hunt
+ * Plays a one minute tone at 10-13 minute intervals. Script 
+ * will check to see if the channel is clear before it will 
+ * transmit.
+ * Connect the HamShield to your Arduino. Screw the antenna 
+ * into the HamShield RF jack. Connect the Arduino to wall power and then 
+ * to your computer via USB. To test, set a HandyTalkie 
+ * to 438MHz. You should hear a one-minute tone every 10-13 minutes.
