/* 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.
