Baofeng Foxhunt Controller: Arduino Shield Prototype
I had some free time and wanted to move the circuit to a more usable/permanent design, so I got an Arduino Uno prototype shield and moved the circuit over. This was my first time doing this type of work, so while my connections ultimately worked, my layout was a bit lackluster, crossed-over wires and most…

Foxhunt Transmitter: Replacing The Relay with a Transistor
One of the first mods I wanted to make to my initial Baofeng Foxhunt Transmitter was to replace the clunky 5v relay with a more efficient transistor to switch the PTT. Not having a lot of electronics engineering experience, I did a little research into some ‘transistor as switch’ circuits and a general purpose NPN…

First Attempt at an Arduino Foxhunt Transmitter
I thought it would be a fun project to try to put together my own foxhunt transmitter. While I initially thought of several ideas for low power transmitters, most designs require some knowledge of transmitter circuits to avoid harmonics and things of this nature. I figured it would be easier to start by leveraging a…
