School Amateur Radio Clubs have inspired a number of very interesting radio and electronic projects. We are developing more all the time. We include them here so that you can be inspired too! Everything is free of course for non-commercial use. Our software is released under the GNU General Public Licence. So you can pretty much do what you want with it, provided you just keep the copyright statement and reference to this site. For those wishing to learn more about Arduino programming please see our Arduino For Amateur Radio Workshop. An excellent eBook on the subject, which can also be used to guide year 5 or 6 students, is Getting Started with Arduino.

High Altitude Balloon Payload MTG004

This project was our first Global Space Balloon Challenge payload. It transmits alternating JT9/JT65 telemetry on 30m SSB. It was launched on 19 April 2015. For more details please see our Amateur Radio magazine article and GippsTech technical presentation:

High Altitude Balloon Payload SARC1

This project is our second Global Space Balloon Challenge payload. It transmits BPSK31 telemetry on 434.650MHz FM. It was launched as part of the 2016 ANZAC Day Amateur Radio Special Event. Both SARC students and Melbourne region Scouts participated in the launch and then tracked the payload on their mobile devices.

Speech Synthesizer for the Yaesu FT-817

This project enables the whole SARC class to hear the frequency, mode and signal strength of our Yaesu FT-817 transceiver. The project was nicknamed "Rachel" after the synthetic British female voice we used for text-to-speech conversion. It could also be useful for operators with impaired vision. For more details please see our Amateur Radio magazine article and source code:

Mini Satellite-Antenna Rotator MkI

This project lets SARC students to track Amateur Radio satellites using our solar-powered, portable, amateur satellite-antenna rotator.

Mini Satellite-Antenna Rotator MkII

This project is a mechanical re-design of the original using the same electronics and software for a medium-duty rotator capable of rotating two, 3m long, cross polarised Yagis.

AIS Receiver

This project lets SARC students track vessels coming into port. It is an Automatic Identification System (AIS) receiver. It picks up information about passing vessels and uploads it to an AIS server over the Internet. Students can check out pictures and information about the ships and costal receiving stations on a web site.

Portable Radio Terminal

This project is a self-contained, portable Amateur Radio station specifically designed for demonstrating Amateur Radio digital modes, receiving High Altitude Balloon telemetry and communicating via Amateur Radio satellites. It can be quickly setup outside in the playground, at a park or even on a mountain summit. It comprises a Yaesu FT-817 transceiver, a Raspberry Pi computer and a sunlight readable touchscreen display. Better still it can be powered from a small 25W solar panel. It can be used to demonstrate all our other projects.

Amateur Radio Direction Finding Telemetry Unit

This project lets SARC students, while engaged in a simulated search and rescue missions, send their ARDF tracker bearings back to base camp using Amateur Radio digital communication mode BPSK31. The device sends the call sign, date, time, latitude, longitude, altitude, azimuth, elevation and checksum over an HF radio link. At the base camp, the fix is decoded on our Raspberry Pi Portable Amateur Radio Terminal using FLDIGI and bearing lines are plotted on a map using OpenStreetMap and OpenLayers. 

Automatic Packet Reporting System on HF

This projects lets SARC students on outdoor missions report their GPS location using the APRS network. A commercial Terminal Node Controller and GPS Receiver are used to send the information over an HF radio link to the APRS Internet Service via a participating APRS IGATE station. Their location can be viewed using a web browser.

Remote Radio Control Server

This project provides full access and control of an Amateur Radio transceiver from anywhere in the world over the Internet. It is used to participate in SARCNET sessions, at lunchtimes, while at work or overseas. A single Raspberry Pi computer provides a Voice over IP server for transmit and receive audio and a Web server to control the rig.
