This week Jeremy spends time with some of our listeners to talk about what’s on THEIR workbenches. We spend time with Mike KM4VKR to discuss his upgrades to the Antenna Analyzer, Vance N3VEM to talk about building his own digital mode interface for his iPhone, and Smitty KR6ZY to learn about his multi-band WSPR experiences. More interviews were recorded and will be available in a future episode.

​George and Jeremy breakdown what it takes to build the new HR360/K6BEZ Antenna Analyzer and where to find all the information you’ll need to make it happen!George and Jeremy breakdown what it takes to build the new HR360/K6BEZ Antenna Analyzer and where to find all the information you’ll need to make it happen!

The K6BEZ antenna analyzer will provide VSWR measurements for any antenna from 1 to 30 MHz.  Frequency and VSWR is shown on the built in LCD display.  Data can optionally be sent over the USB cable to a PC running a program that will plot the VSWR on a graphical window display.  The analyzer can be programmed to scan any sub band and has built in ranges for 160m, 80m, 60m, 40m, 30m, 20m, 17m, 15m, 12m, 10m.

George and Jeremy KF7IJZ are joined by Beric Dunn K6BEZ and Nick Garner N3WG to design an “idiot switch” – a micro controller device that can remove power from a soldering iron when the user leaves it turned on too long (Like Jeremy himself did with a Hakko FX-888 for 2 weeks!).

George and Jeremy sit down with Beric Dunn (K6BEZ), the designer of the project, to introduce the Arduino powered DDS module based Antenna Analyzer!  Beric is a professional RF design engineer by trade, and he wanted to provide a project that would allow a ham to learn some fundamental principles while making a useful gadget.
