I successfully transmitted live GPS data between DNT900 radios!

The remote radio is under Arduino control where I built a DNT900 library to interact with the radio.  This allows the main program to capture GPS data, format it for transmission, and transmit it to the base.
The base radio has a similar DNT900 library in C#.  The program, a prototype for a larger data management program, captures and displays the GPS data sent from the remote.  The transmission distance was about two meters.

The transmission of live GPS data has been a goal since last December.  With this milestone, I am planning next steps.  Certainly the end result is a PC board, however I want to evaluate longer distances, and provide for peripheral devices (limit switches, temperature probes, pressure sensors, and the like).
