/* 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.
