\section{RF} \subsection{Overview} After affixing the header, the packet is ready to be transmitted as RF. The following modulation parameters should be used: \begin{itemize} \item Modulation Scheme: 2-FSK \item Bit rate: 9600 bits/s \item Deviation: 4.8 KHz \item Frequency: 430.500 MHz \item Sum of transmission ramp-up/ramp-down time: $< 1$ ms \end{itemize}
