We run a small Internet business from home. Called The School Amateur Radio Club Network, you can visit our website at

Together we have set up and run three School Amateur Radio Clubs at Julie's Primary Schools. We have also run various Radio and Electronics Workshops and School Excursions. We set up trading tables at The Melbourne Train and Hobby Show and at local Amateur Radio Hamfests.

This page is really all about the fun we are having running our business at home.

We manufacture and sell a small, portable Satellite Antenna Rotator Controller and TRACker called SARCTRAC.

It is used to point a small antenna at any one of thousands of orbiting satellites, including the International Space Station. By connecting the antenna to a radio you can receive and sometimes transmit signals to the orbiting platform.
