## Early Static Test

Recently i performed a static test to see whether the Arduino-APRS could send the packet via Radio. Sure it could !

* See how it was reporting the GPS positions while it still trying to aquire the most accurate position over time ([https://aprs.fi](https://aprs.fi) , [https://aprs.fi/info/a/YD1SDL-1](https://aprs.fi/info/a/YD1SDL-1)).

* Make the code more efficient and nicer. (there's a lot of room for improvement!)
