thanks paul! Or i guess the overall goal for those not as into radio, is to send text messages Via radio frequency. (turn written text into a transmittable sound with an onscreen user friendly GUI.) i already have transmitters i just need to be able to send/receive the text(sounds) to input into the transmitter and display the RX/TX on the screen. the APRSdroid Application however seemed to already do that and offer more features albeit probably more complicated to adapt to arduino?
