Special thanks to Clifford Heath for his help putting together the radio demo, and the folks at the Victorian ARDF group for connecting us.

Thank you to Brian Harrison and Michael Murphy with the AWA Communication Technologies Museum for their assistance with early research.

Thank you to Peter Bevelacqua over at Antenna Theory for help filling in some missing details.

Sharp-eyed viewers might notice there doesn’t seem to be a loop antenna in the flight simulation shots. It sadly wasn’t included in the simulator’s model of Earhart’s Electra, but it features prominently in old photos.

I worked at Tesla starting in July of 2017 as an Operations Analyst out of the Bethlehem, PA distribution center facility and left as a Program Manager based out of Austin, TX as of September 2021. I spent most of my time in the distribution and supply chain organizations.

Before Tesla, I was a Director of Business Intelligence and Pricing at the largest Pet Food & Supply distributor in the US, Phillips Pet Food & Supplies based out of Easton, PA. My wife and I also owned a small business in Bethlehem, PA between 2016 and 2019.

I have been a shareholder of Tesla since 2012 and currently own Tesla stock. Nothing I say constitutes as investment or financial advice.
