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.

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. Simply mount it on your tripod; attach it to your hand-held satellite antenna using your counterbalanced lift-arm; connect it to your radio transceiver and battery; strap on the SARCTRAC 3D sensor to your antenna boom; then use your WiFi-enabled mobile device to control SARCTRAC and select the satellites you want to track. SARCTRAC will predict future satellite passes, track each satellite in turn and even tune you radio to the correct frequency for each overhead pass. 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! Note: SARCTRAC comes with its own test stand and a test lift-arm for demonstration purposes.

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!

We are not taking orders, yet, but you can register your interest here.

    Our preliminary expectations for SARCTRAC Mk3 are:
    1. A cheaper unit: AU$300 (Approx. US$225, including shipping to US).
    2. Production of 100 fully assembled and calibrated units by end 2021.
    3. ESP8266 not RPi based – Lower power. No heatsink. Lower RFI. Better EMC.
    4. The rotator can be mounted remotely – up to 30m/100ft away.
    5. The radios can be mounted in the shack and controlled by a PC – not supplied.
    6. Uses popular, some free, PC-based, 3rd party, satellite tracker/radio controller applications – not supplied.
    7. Includes a new setup and operating instruction manual.
    8. Includes a dedicated USB Dongle, wireless link, from the PC to the rotator – No WiFi Router/Hotspot configuration required.
