OPERATING : Worked All Plymouth, AF3K/AF4K, DLM Antenna

About a week ago, Tom, KE8HUM, answered my CQ. He lives in Plymouth, MI, only 12 miles from me, according to QRZ.Com. He apologized, but I enjoy working guys no matter where they are. He’s a member of our club, a nice guy, and I have his QSL in my collection of QSL cards from stations whose call signs spell words.

About an hour and a half later, I was still down in the shack and worked Gary, K1YAN, Plymouth, MA.

According to the Boston Globe, there are 30 cities in the U.S. alone with the name Plymouth.

OPINION : Can the Jetson Nano Bring AI to Amateur Radio?

Arduinos are fun, and Raspberry Pis are cool, and hams have been quick to adopt these platforms and use them in amateur radio applications. The latest small computer—the NVIDA Jetson Nano—could take this to a whole new level.

The Nano is the newest and the smallest of the NVIDIA Jetson Series of machine learning (ML) enabled computer boards (shown below). It come is a DIMM package measuring only 70 x 45 mm. Despite the small size, the specs are very impressive:

  • 64-bit, quad-core ARM Cortex-A57 CPU complex

  • 128-CUDA-core Maxwell GPGPU designed to handle video streams as well as ML chores

  • 472 GFLOPS of performance.

OPINION : Is Your QST App on iOS Busted? Ours is too…

Oh, at least 15 years or so ago, a university team in the UK came up with an electronic ink (e-ink) technology for an 8″x11″ format thin tablet for office use. It was going to revolutionize photocopying by reducing the need for it. Recall when corporate (and university!) meetings would be held after burning down the photocopier with reams and reams of memos, white papers, and so forth? The team in England had a budding product that would just nip that in the bud. Except, it never got released. It just wasn’t ready for market. The team went back to the drawing board and disappeared from the marketplace.
