![]() Instructions also seem to be located here. ![]() Definitely attractive! It’s built on the same premise: AD9850 DDS board, Arduino, etc., but seems to use fewer components. He replied with yet another option in the form of a PDF by K6BEZ who claims to accomplish the same feat in < $50. A Cheaper Alternative?Īfter I read the article, I emailed Mike AB1YK to let him know about it. ![]() I would certainly like to tackle it and have added it near the top of my to-do list since it seems like it can be accomplished within a weekend. Having not built this yet, I would say this would be an intriguing build for someone. ![]() Though this is not essential, it may aid in the build. The authors also quote that one helpful component is purchasing their own custom PCB for the job itself. Completed assembly of analyzer View of Arduino, PCB, and components for analyzerĪ downside is that the number of components required seems to be somewhat large as seen from Farrukh’s website which could potentially be overwhelming if you are just beginning. so this makes it relatively easy for the user. There seems to be a lot of documentation on the assembly, parts, etc. So, this leaves the user with the experience and satisfaction of homebrewing a really useful component for the shack. Additionally, on the main website, one can also download the associated software to load on the Arduino. The major components are comprised of an Arduino, AD9850 Direct-Digital Synthesizer (DDS) board, and TFT display. The attractive thing about this design is the authors quote a price point of $50. Especially because I would rather put that money towards a Heil headset and foot pedal (to be ordered for Xmas 2017).Īt the October Board of Directors (BoD) meeting, Fred AB1OC mentioned that in the Nov 2017 issue of QST, there was an article entitled “ Build Your Own Arduino-Based Antenna Analyzer” by Jack Purdum W8EEE and Farrukh Zia K2ZIA. When I first strung up my Buckmaster 7-band OCF dipole, I borrowed the RigExpert AA-30 from Greg W1TEN, in order to measure the VSWR, since I wasn’t thrilled about spending $200 for the analyzer. I could be wrong, but antenna analyzers kind of feel like a one-trick pony to me. In other words, it’s easier for me to spend more money when I feel like my purchase is not exactly a swiss-army knife but also not a one-trick pony. ![]() So, if I am going to spend $$$ (on a scale of $, $$, and $$$), I want to make sure not only am I obtaining quality, but also multi-functionality. Ideally, it would be great to spend $ and get the highest quality in return. If you’re like me, then you try to be judicious with your $$$. ![]()
