Mark your calendars! The most anticipated event in amateur radio is just around the corner. ARRL Field Day 2026 is officially set for the fourth full weekend in June: June 27–28, 2026.
Whether you are a seasoned contester, a digital mode enthusiast, or a brand-new ham looking to make your first contact, Field Day is the ultimate “open house” for our hobby. It’s part emergency exercise, part contest, and 100% community.
The 2026 Message: “Resilience Through Connection”
Every year, Field Day reminds us why we do what we do. In an era where communication is often taken for granted, the 2026 focus remains clear: Science, Skill, and Service.
The goal isn’t just to rack up points; it’s to prove that when the grid goes down, and the “normal” world goes quiet, amateur radio operators are ready. This year, we are placing a special emphasis on:
Emergency Preparedness: Testing our gear in “less-than-optimal” conditions.
Technical Growth: Experimenting with new antennas, solar power, and portable deployments.
Public Outreach: Showing our neighbors that ham radio is a modern, vital resource for the community.
Call to Action: Start Planning NOW!
A successful Field Day doesn’t happen by accident—it’s the result of teamwork and early preparation. We are calling on all club members to step up and help make 2026 our best year yet.
Here is how you can jump in right now:
Join a Committee: We need leads for Site Selection, Antenna Safety, Food/Logistics, and Public Relations.
Inventory Your Gear: Dust off those portable rigs, check your battery health, and inspect your coax. Don’t wait until June 26th to find a blown fuse!
The GOTA Station: We need “coaches” for our Get On The Air station. If you enjoy mentoring new hams or curious visitors, this is your time to shine.
Bonus Point Hunting: From satellite contacts to copying the W1AW bulletin, there are dozens of ways to boost our club score. Who wants to take the lead on the Section Manager message this year?
Event Details at a Glance:
When: June 27 (1800 UTC) to June 28 (2059 UTC)
Where: TBD – will update as soon as possible
Objective: To contact as many stations as possible and learn to operate in abnormal situations.
Let’s show the world what we can do! Check your email for the next planning meeting date, or reach out to the Club President to volunteer for a specific role.

A few years ago, I decided to upgrade my PC. In researching, I found a mini fan-less PC that runs on a 12v wall wart. After researching my software wouldn’t have any issues I purchased and installed the software I use.
The only issue I had was that even with my off the shelf UPS system the PC would reboot during bad weather. I investigated and found the wall wart was susceptible to power line transits.I thought about using one of my ham radio power supplies, which I thought was way over kill.
Searching the internet I found that battery operation was preferable. But then again it was much more than I needed. Then on “YouTube” I found them using an oversize AA with a voltage of 3.7v. This is actually called a 18650 cell as the designated size. What was impressive was the different capacities viable on “Amazon”. These cost from $2.25 in multiples and capacities from 2000mah to 9900mah
More research indicated I could build a DIY UPS with no switching time and a fairly large run time. Since the most time I have been without power has been less than 1 hour. So I sat down and worked out a wiring diagram. The schematics program I use is called “Fritzing”. Here is a link to the webpage for the software. https://fritzing.org/

The Future-
Since I also operate a couple of Raspberry Pi’s 24/7, I am refining the schematic with a couple of changes and will build one for 5v.
