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! # 5:21 pm
