Antenna Analysis from Ham Radio to PCBs

Has anyone else ever thought about why so many engineers are also active amateur radio operators? My theory is that there's just so much passion for the science and practical use of these complex electronic systems! We enjoy the problems, challenges and solutions so much that we want to find other ways outside of work to find those same experiences. In this case, I've got a story that starts with some amateur radio equipment but comes full-circle to address an extremely common design issue. The Attempted QSO This all begins with a new radio. I recently installed the FTM-3200DR1, a 2m-band, 65W transceiver with Yaesu's digital C4FM modulation.

NDAA Implications for Design Engineers

I recently found out about the latest National Defense Authorization Act (from I-Connect007) and a new provision for printed circuit boards with some government contract procurement rules. If you made it through that first sentence, then there's a good chance the rest of this article won't be too boring for you! This seems like it's a bit of a dry subject, but it's got me excited for what it means for the future of both PCB manufacturing as well as broader economic impacts in our country. In this article, I'm going to try to explain these provisions (at least to the best of my limited ability to understand them) but more importantly I've got some predictions about what this means for the design engineer (since I'm sure most discussion of the NDAA will probably talk about it only from the perspective of the fabricators and assemblers).
