µBITX project
Just had to build one of these www.hfsignals.com/index.php/ubitx/. So here is my µBITX project, for the price of 2 crystals for a Codan lunch box, I get a full HF rig! It had to go into an ammunition box, a bit tight in one of the dimensions, and if I was to do this again, […]
Flower Pot Antenna on a wire
Here is a very handy aerial for permanent and field day installations. We’ve used VK2ZOI Half-Wave Flower Pot Antenna’s design, however we’ve only used the UPVC conduit for the choke section. This gives us a 2m aerial on a wire. It can be raised by pulling from the top, typically with a rope over a […]

VK2RL’s RETRO-STYLE CARDBOARD RADIO
THE RETRO-STYLE CARDBOARD RADIO MAKER: BOB VK2RL This highly educational and quirky project is suitable for a rainy day, and is an ideal way to use up surplus electronic components that may happen to be lying around the workshop. Basically it consists of a TA7642 integrated circuit that is constructed using discrete components – i.e. transistors, resistors […]
Yves VK2AUJ shows off his great KX3 Carry Case
Having spent $1,800 on a radio, I wan’t a box to be able to carry it around. It had to be convenient so that I would only have to open the lid and operate! http://www.youtube.com/watch?v=SFbuM5M3SnU
Using your iPhone for APRS (with no internet)
I had a quick look at some iPhone APRS applications that used GSM connectivity to the Internet to publish my location, whilst those work very well when you have reception it isn’t as exciting as using RF to transmit your packets. Cue an Application called Pocket Packet. Pocket Packet uses the iPhones built in GPS […]

The receiver was built as a prototype because I was uncertain as to how much experimentation was going to be necessary in order to get it going. There were some […]
