Build your own echolink node using the raspberry pi for 100 euro.
Small unix devices like the raspberry pi, beaglebone, pogoplug and others are proving to be very usefull tools for all kind of ham related applications. They have been used in project involving D-STAR, rig-control and wspr server, for APRS node and other.
This project looks at another aspect of amateur radio: echolink.
The aim of this article is to describe how to create a complete echolink linknode using raspberry pi; complete for around 100 euro. The goal is to provide a platform to allow people to get their first experience with the raspberry pi, with interfacing computers and radios and with setting up ham infrastructure.
The hardware components needed for this project are:
- A raspberry pi + power + case + SD card
- A USB audio-fob
- (optionally) a USB-to-serial adapter
- A “digital modes” interface board (either self build or commercial)
- A handheld radio + (by preference) an external power-supply
- An external antenna
This project aims at using as much as possible homebrew equipement and off-the-shelf components.
