The amateur radio hobby.

The rich history of ham radio culture (via) This long excerpt from Kristen Haring's 2008 book Ham Radio's Technical Culture filled in so many gaps for me. I'm ham licensed in the USA (see my recent notes on passing the general exam) but prior to reading this I hadn't appreciated quite how much the 100+ year history of the hobby explains the way it works today. Some ham abbreviations derive from the Phillips Code created in 1879!
The Hacker News thread attracted some delightful personal stories from older ham operators: "my exposure to ham radio really started in the 1970s...". I also liked this description of the core of the hobby:
A ham radio license is permission from your country's government to get on the air for the sake of playing with radio waves and communicating with other hams locally or around the globe without any further agenda.
I'm increasingly using the Listen to Page feature in my iPhone's Mobile Safari to read long-form articles like this one, which means I can do household chores at the same time.
About ARDC (Amateur Radio Digital Communications). In ham radio adjacent news, here's a foundation that it's worth knowing about:
ARDC makes grants to projects and organizations that are experimenting with new ways to advance both amateur radio and digital communication science.
In 1981 they were issued the entire 44.x.x.x block of IP addresses - 16 million in total. In 2019 they sold a quarter of those IPs to Amazon for about $100 million, providing them with a very healthy endowment from which they can run their grants program!
Ham radio general exam question pool as JSON. I scraped a pass of my Ham radio general exam this morning. One of the tools I used to help me pass was a Datasette instance with all 429 questions from the official question pool. I've published that raw data as JSON on GitHub, which I converted from the official question pool document using an Observable notebook.
