School Amateur Radio Clubs have inspired a number of very interesting radio and electronics projects. We are developing more all the time. Some of our most popular projects have now been turned into products for sale in the hope they will encourage more youngsters into STEM through the development of School Amateur Radio Clubs. Of course we will always continue to offer free project information, software and support where we can. We have secured our website and we use the secure PayPal server. We aim to provide high quality hardware and software. Each of our products is fully checked and tested before shipment.

Mini Morse Code Practice Set
International Morse Code
This is one thing that really surprised us: Kids love Morse code. It fascinates them and they pick it up quickly. We used to do our Morse code activity with a Hi-Mound HK704 straight key and oscillator. But that setup costs over A$140, so we can't use it to do a class or group activity. The answer was to design our own Mini Morse Code Practice Set. And for A$10, it is a hit! Now, for the cost of coffee and a donut, kids can have their own set to take home. It comes with a microswitch, simulating a real telegraph key with a nice click-click action, a 2.5kHz sounder, a 3V lithium battery (CR2032) for up to 36 hours of continuous tone operation, all mounted on a double-sided PCB with a non-slip base. It measures only 64x36x15mm and fits in the palm of your hand. It comes in a zip-lock bag, with a laminated, credit-card size, Morse code chart and instructions.

  • This product is only available for shipping to Australia and Worldwide in quantities of 20, lithium batteries not included.
  • Other quanities, lithium batteries inluded, are available for only A$10 each, pick-up by prior arrangement only. Contact us to arrange pickup.
