* FUNCTION DESCRIPTION:
* This function tunes the si4010 for transmission and transmits frames.
* It consists of two fundamental phases, setup and the transmission loop.
*
* Setup Phase:
* The Setup Phase calls all setup function for the need API modules.
* These functions are to be called once per boot of the chip.
* vSys_Setup
* vPa_Setup
* vOds_Setup
* vStl_EncodeSetup
* vFCast_Setup
*
* Transmission Loop Phase:
* The Transmission Loop Phase is a loop which transmits the proper frame
* once a button is pushed. Frequency casting, FSK adjustment
* and PA tuning are all performed between each transmission.
