APRS on the Arduino

I was able to receive aprs packets via my arduino!

I built a connector from the new VX-3 radio to the arduino radio shield. Then through some trial and error I was able to receive aprs packets as plain text on the arduino. Took me a while to figure out the necessary settings on the radio (turn off power save, and set the volume to '15' basically). This will allow me to send short text messages to the handheld radio (which will be located in a future balloon). Once I have the aprs formatting down I can also send out messages from the arduino as well. This will allow me to have basic two way communication to the balloon over a long distance.
