 \chapter{Construction}
 I used a stripboard for the circuit (see photo on the front cover page and
 the layout in appendix~\ref{stripboard}).  The steps I took are similar to
-the typical suggestions for how to solder components, but I chose to build
-everything in sections.  This allowed me to check that everything
-constructed still worked before moving onto more components.

 I started with the main circuit first, then the Baofeng interface board, and
 finally the power supply section.  The main circuit and the power supply are
