1a) Emergency Preparedness
One of the challenges we faced during the flood that wreaked havoc in our area in 2013 was that our community was separated into "islands" that were physically cut off from each other and the rest of the world by the flood waters.
Having lost power, internet, landlines, and cellular service, we also were cut off from communicating with anyone outside our islands, including emergency services. For the better part of three days, we were in a very strange limbo.
To address this type of scenario in the future, as well as to enhance community emergency preparedness in general, we formed Lyons Prepared, a volunteer organization.
At the recommendation of our local fire district and sheriff's department, Lyons Prepared adopted MURS radios to provide backup communication between our neighborhoods and local emergency services.
1b) Amateur radio
My personal desire for more robust communication capabilities inspired me to also get my ham radio license and to join our local Amateur Radio Emergency Service organization, Boulder & Broomfield Counties ARES, as well as the nearby Longmont Amateur Radio Club, w0eno.org.
A couple of us also started an informal local net to strengthen the ham radio network in our area: Lyons Area Amateur Radio Net (laarn.net).
As I've gotten more involved in amateur radio, I've grown to appreciate what unique and wonderful opportunities it presents to serve our communities, learn new things, and have a good time. There's an article in the January 2000 issue of QST, the magazine published by ARRL (American Radio Relay League), that provides a great perspective on this: "Amateur Radio: 100 Years of Discovery" (PDF) by Jim Maxwell, W6CF.
Thanks to the following mentors and learning resources:
- George, KA0BSA, of Boulder & Broomfield Counties ARES, who taught our Technician License course, helping me launch into ham radio, and who has been a generous Elmer to me ever since.
- Bryan, AFØW, and Kat, WØUM, of Longmont Amateur Radio Club, who taught our General License Course.
- Technician and General License Course by Stu Turner, W0STU, HamRadioSchool.com.
- General Class License Manual by The ARRL, www.arrl.org.
- HAMSTUDY.org and HamTestOnline.

2) Reflections of an amateur amateur
Although I'm still relatively new to the universe of ham radio, I've already stubbed my toes enough times to have had a few experiences that I figure might be worth sharing. In the same spirit that motivates me to share my reflections about woodworking and the tools I use, I'm going to share info I wish I had found when I was browsing for ham-related insights.
2a) My "shack"
Yep, I'm a bit scrappy. My shack is a corner of a desk in my workshop, which is primarily a haven for my woodworking passion. My shop is so full of woodworking tools that there's not a lot of free space, so I have to make use of every square inch, for example, the monitor I use when logging into the Raspberry Pi is balanced on top of the water heater next to my desk. Hey, it works!
Analog – Dual band Kenwood TM-V71A with an RC-D710 control panel for APRS. (I also use a TM-V71A in my car.) It's a good base station for my purposes, given my focus on local-area emergency communications.
2b) Mobile install
I'm not much of a car guy, so I'm pretty satisfied with—and a little surprised by—how well my car installation turned out, thanks to a combination of lots of sweat and even more luck.
2c) Diving into D-Star
When I first dove into D‑STAR, I knew nearly nothing about digital voice and quickly found myself drowning in a big bowl of bewilderingly murky information soup. SOS!
So if it's that bewildering, why even bother?
I'll jump a bit ahead here and share one tidbit: at one point early in my exploration of D‑STAR, I linked to a reflector and heard a guy in San Diego, California chatting with a chap in Yorkshire, England. That was the moment I became hooked!
2d) Trying to understand DMR
After weeks of intense learning and effort, I felt like I was just beginning to get a handle on D-STAR, having put together a nicely working solution for my shack as well as for mobile. So why did so quickly adventure off in a new direction?
I guess I must be a bit crazy, but a learning opportunity presented itself, so I decided to dive right back into another bowl of baffling info-soup and learn how to swim all over again, this time in the DMR soup bowl.
⇄ Give me a holler!
