Detailed Description

Software module to control the power on and set up of a UHF radio that can be attached to u_Track.

This software module can be configured to turn on the radio and set the frquency, bandwith and power for transmission. If there is an error when configuring the radio the module will power down the radio

Precondition

First initialise the SERIAL UART.
