A new kind of HAM Radio controller and toolbox 

Wizkers Radio

Presented by Edouard, W6ELA, Founder of wizkers logo Wizkers: Radio  

What if someone told you: you can use ANY computer to control and configure your rig - it doesn't matter if you are a Windows, MacOS, Linux, Android or even Chromebook user?

This presentation is about a new open source application, Wizkers:Radio, built on top of the http://wizkers.io/ framework, that is a universal rig controller, radio configurator and general HAM RADIO Swiss army knife.

Eduoard will describe the capabilities of Wizkers:Radio, how you can use it on your phone or computer, including Raspberry Pi's, and how you can contribute to its further development.

Have a look at http://wizkers.io/wizkersradio for more information - Eduoard will be ready to answer any question you have during the presentation and mention some thoughts for future applications of Wizkers:Radio.

Yagi-Uda Antennas 

Yagi Uda

Presented by Gary Thiele, KD8ZWS

The Yagi-Uda antenna was invented in Japan in 1926 and saw use in early WWII as a VHF radar antenna.  In 1943 the (classified) invention of the Magnetron enabled the Allies to develop airborne radar at centimeter wavelengths (for which other antennas were more suitable). The technological advance of allied airborne radar contributed significantly to the demise of the German U-boats.  After the war, the Yagi-Uda became a favorite Ham antenna.

The talk, in four parts, will: 1) trace the historical development and use of the Yagi-Uda;  2) reflect on some personal experiences; 3) review some antenna basics; 4) conclude with a brief technical discussion that will show why the director and reflector elements are configured as they usually are, and why the antenna has narrow bandwidth, among other characteristics.

Gary Thiele is co-author of the book “Antenna Theory & Design,” Wiley 1981, 1998, and 2013 (822 pages).  The text serves both the academic market and industrial users.
