Radio Adapter Board

Adapter board to connect a Yaesu VX-8DR with a Garmin GPSmap64 and various .mil microphones

Requirements

• Arduino
• Eagle
• You must copy ucontroller-code/platform.local.txt to your $ARDUINO_HOME/hardware/arduino/avr directory to enable printf formatting of floats

Table of Contents

Directory	Contents
ucontroller-code	Arduino sketch to translate Garmin GPS NMEA sentences into the fixed-length that the Yaesu VX-8DR expects
circuit-board	Eagle circuit diagrams and PCB layouts for the adapter board
dev-tools	Various Python scripts that were useful during development

Important Note

The ATmega328p chips I got needed to have their fuses set, there is a script set-fuses.sh that will do this for you. You may need to change the programmer from usbtiny to whatever you have on hand.
