\section{Programming a Rugged Radio}
%======================================================================

Programming is used in order to have preset channels and set for ease
of use for all users.

%======================================================================
\subsection{Installing CHIRP}

Download and install KK7DS Python runtime from:

\vspace{0.1in}
\noindent
\urlx{http://www.d-rats.com/download/OSX_Runtime/KK7DS_Python_Runtime_R10.pkg}

\pskip
\noindent Download the CHIRP radio programmer from:

%======================================================================
\subsection{Installing Needed Drivers}

\begin{enumerate}
\item Navigate to: \urlx{http://www.prolific.com.tw/US/CustomerLogin.aspx}
\item Login (Username: GUEST, Password: GUEST)
\item Select the link titled "Click here for PL2303 USB to Serial Drivers"
\item Download and install the latest "Mac OS X Universal Binary Driver"
\end{enumerate}

%======================================================================
\subsection{Programming}

{\bf Cloning exiting setings:}

\pskip
\noindent
Plug the programming cable into your and the radio that you wish to
program.  Make sure that the plugged into the radio all the way.

\pskip
\noindent
Launch the CHIRP application. Select "Radio --&gt; Download From Radio"
and configure to look like the picture below

  \caption{The correct settings for a RH-5R radio}
  \label{chirp_radio_settings}
\end{figure}
\vspace{0.15in}

\noindent
Click okay and follow the instructions given by the prompts that pop
up. Once the settings have been cloned you can preceed to edit the
configurations however you like.

\vspace{0.3in}
\noindent {\bf Editing}

\pskip
\noindent
Below is what the PavLab currently uses for presets on all radios.

  \label{pavlab_channels}
\end{figure}
\vspace{0.15in}

\vspace{0.3in}
\noindent {\bf Uploading}

\noindent
After you are done editing the settings you can simply select "Radio
--&gt; Upload To Radio" in order to put the new configured
settings on to the radio.

%======================================================================
\section{Radio Operation}
%======================================================================

%======================================================================
\subsection{Basic operation}

\noindent
{\bf Turning the radio on}

\noindent
In order to turn on the radio you turn the nob on the top of the radio
clockwise until you feel a click.  This same nob can be turned further
to ajust the volume.

\vspace{0.15in}
\begin{figure}[H]
  \centering 
  \includegraphics[width=0.28\textwidth]{figures/RadioTurnOn.JPG}
  \label{turning_radio_on}
\end{figure}
\vspace{0.15in}

\vspace{0.3in}
\noindent
{\bf Talking on the radio}

\noindent
To transmit on the radio you need to push the push to talk or "PTT"
button on the left side of the radio.  If you are having issues with
being heard on the radio, it might be a good idea to hold down the PTT
button for about 1 second before and after you talk

\vspace{0.15in}
\begin{figure}[H]
  \centering 
  \includegraphics[width=0.3\textwidth]{figures/RadioPTT.JPG}
  \label{ptt_radio}
\end{figure}

%======================================================================
\subsection{Changing Channels}

Once you turn on the radio you should see a screen similar to the one below

\vspace{0.15in}
\begin{figure}[H]
  \centering 
  \includegraphics[width=0.3\textwidth]{figures/RadioScreen.JPG}
  \label{radio_screen}
\end{figure}
\vspace{0.15in}

\noindent
In order to switch channels you must first unlock the keypad by
holding down the lock button \textit{(shown in green)}. Once the lock
icon \textit{(shown in blue)} disappears from the screen you are ready
to change the channel. Select the frequency you wish to change by
pushing the "A/B" button \textit{(shown in yellow)}. After you have
selected the frequency you wish to change you can switch between
preset by pushing the up and down buttons \textit{(shown in red)}.

\vspace{0.15in}
\begin{figure}[H]
  \centering 
  \includegraphics[width=0.28\textwidth]{figures/RadioChannelButtons.JPG}
  \label{radio_channel_buttons}
\end{figure}
\vspace{0.15in}

\noindent
In the picture above you can see that the radio has two "FRS9"
channels. These channels do not have to be the same in order for the
radio to operate. You can set one to "FRS9" and one to "SEA 69", for
example, and then switch between the two on the fly with the "A/B"
button on the radio.
