Products
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 has a microswitch, simulating a real telegraph key with a nice click-click action and a 2.5kHz sounder, 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. It requires a 3V lithium battery (CR2032) not included for up to 36 hours of continuous tone operation. Note: A free lithium battery is provided to pickup customers only.

SARCTRAC Mk3
Satellite Antenna Rotator Controller and TRACker
SARCTRAC is a portable, integrated, satellite tracking system, which is now available as a fully assembled, tested and calibrated product. It provides a wireless connection to the same Windows or Linux PC and satellite tracking software you use to control your Amateur Radio transceiver (rig). With a SARCTRAC system and your own equipment you can listen to orbiting space beacons, make two-way satellite contacts and use free, third-party software to download earth images and decode satellite telemetry. It's both fun and educational!

New for 2020: The Amateur Radio International Space Station (ARISS) team and NASA have installed a permanent radio repeater on board the ISS. So now you can use SARCTRAC to listen and talk to other Amateur Radio enthusiasts via the ISS!

To get started you need to:
  • Make a counterbalanced lift-arm to attach your favorite hand-held satellite antenna to SARCTRAC
  • Make your own tripod mount for SARCTRAC
  • Connect your rig to your Windows or Linux PC via your rig's CAT cable
  • Download a free satellite tracking application like Gpredict™, SatPC32™ or Orbitron™ or
  • Download low cost, feature-rich tracking applications like PstRotator™, SatPC32™

To set up and use SARCTRAC you need to:
  • Attach SARCTRAC to your tripod
  • Attach the your antenna assembly to SARCTRAC

CURRENT STATUS:
SARCTRAC Mk3 IS CURRENTLY IN PRODUCTION!
Current Production Status (29 September 2021)
14 out of 20 Steps Completed. 2 In Progress.
AVAILABILITY OF PARTS ORDERED (SOME DELAYED DUE TO COVID)
34 out of 37 Available
REGISTRATION OF INTEREST FOR 200 PRODUCTION UNITS IN 2021
149 out of 200 Interested

We have completed the design and coding of SARCTRAC Mk3, addressing many user, hardware, software, integration, production and support issues. It will be housed in the same enclosure, with the same motors, drivers and sensor as SARCTRAC Mk2. It does not have a built-in tracking application. Instead, it will allow the user to run their own satellite tracking/radio control software from a PC at the radio operating position, while providing its own dedicated wireless connection to the rotator. The sensor and processor are now mounted on a PCB in a water-proof enclosure at the end of the lift-arm. There is a USB Dongle for connection to the PC. The unit has now passed testing with PstRotator™, Gpredict™, SatPC32™ and Orbitron™.

We are not taking orders, yet, but you can register your interest here. We will let you know when production is complete. If you are not successful in getting a unit from the current production, you will be given priority for the next production. Please don't email us to request status updates or estimated completion dates. All the information we have is provided here and is updated as it changes. We try to be totally transparent and fair to everyone.

Current expectations:
  • Some production parts have been delayed due to COVID.
  • On 5 September 2021 we ordered production parts for another batch of 100 units: Due December 2021.
  • Production of 100 fully assembled and calibrated units by end of October 2021 is still possible at this stage.
  • SARCTRAC Mk3 will be a cheaper unit: RRP AU$300 (Approx. US$225, including international shipping).
  • See SARCTRAC Mk3 features here.
  • There is also the possibility of a future SARCTRAC Mk3 kit, around December 2021!
    • Would include a fully assembled, tested and calibrated 3D Sensor and a USB WiFi dongle.
    • Connect the 3D Sensor 6-way cable to your own power supply and motor driver.
    • Connect your own motors to the motor driver e.g. DC or AC motors.
    • Connect the USB WiFi dongle to your PC and use your own satellite tracking software.
    • Attach you own quick-disconnect DC power connectors and safety lanyard (Important).
    • Would work with our Mini Satellite-Antenna Rotator Mk1B, Mini Satellite-Antenna Rotator Mk1C and Mini Satellite-Antenna Rotator Mk2.
    • The RRP of the SARCTRAC Mk3 kit would be around AU$200 (Approx. US$148, including international shipping).
