Well it’s final and unfortunate at the same time.
Well, it’s official and unfortunate at the same time, Ria Jairam N2RJ as of March 31 2023 will step down as a director on the ARRL board. Ria before the ARRL was involved in many areas of amateur radio including a very informative YouTube channel. As a director on the ARRL board, she was young blood, fresh input and a starting point for the ARRL to connect to the younger crowd.
While on the board she wrote a book on how to pass the Technicians class Amateur Radio exam. Before the book was published she approached the ARRL ethics and election committee and received their approval to go ahead. After the fact, the committee back-stepped on their decision. Ria took the proper steps and the ARRL changed its minds once the ball was rolling. This resulted was Ria being recused from certain decisions with no end date given.
On March 28th, 2023 Ria informed the ARRL as of March 31 2023 she will step down. Very unfortunate for the ARRL ( which I am a member). The ARRL “had” their second female board member, a young person and someone committed to spreading the Amateur radio gospel.

New Book: Learning, Living, and Loving Morse Code…
There is a new book from a fellow Morse code amateur radio operator, Chris Rutkowski (NW6V), about “Learning, Living, and Loving Morse Code (in a Digital World).” NICE!
Title: “The CW Way of Life“
link: https://amzn.to/3Tm3KfD
I received a new book! Here it is, at my radio shack operations desk, at NW7US radio station.
Already, I think it rivals any other book on the topic, including “The Art and Skill of…,” or, “The Zen of…”
It is not, however, meant to replace, but to augment, what is available. But, it is a complete guide, including a “work book” section (nearly half of the book?) on how to improve your skill. Really good stuff, but I’m only in one day.
