Hello Operators,
This is Julian, author, videographer, US expat, and ham radio operator living in Finland.
This channel focuses on portable, pragmatic off-grid and grid-down power and radio communications for preparedness. The goal is to help operators use portable power, HF radios, and data-mode communications as real-world utilities at home or in the field.
I usually publish two videos and two blog posts monthly. You can also find my work on YouTube, X, Instagram, my blog, and in my Grid-Down Emergency Communications book series on Amazon Kindle and in print.
The channel covers ham radio off-grid, solar-powered radio, data modes, portable radio, DIY LiFePO4 batteries, tutorials, field tests, reviews, and DIY projects.
Channel motto: Maximize Capability, Minimize Gear!
This is a family-friendly channel.

Hello Operators
Radio Antenna Handbook for SHTF is now available on Amazon Kindle.
This handbook brings together the antenna systems covered throughout my field work and organizes them into a structured, practical reference. The focus is deployment under real conditions: limited power, limited supports, difficult terrain, harsh weather, and time constraints.
Inside you’ll find:
Practical dipole, OCFD, and EFHW deployments
NVIS configuration guidance for 80 m, 60 m, and 40 m
Portable vertical systems and shortened field antennas
Counterpoise management and ground considerations
Troubleshooting tools and field diagnostics
A physics-based look at 11-meter CB antennas and how to build them correctly
The emphasis is on selecting the right antenna for the mission, understanding trade-offs, and achieving repeatable results in the field.
If you operate HF or 11-meter CB and want a clear, pragmatic guide to antenna deployment in off-grid or emergency conditions, the Kindle edition is available now.
As is often the case, I’ll be fine-tuning the manuscript over the next few days before publishing the paperback. A print-ready PDF will also be published through Patreon and Ko-fi.

The IC-705 changed portable radio. But it’s not finished. If I were Icom, I’d complete the circle. Fewer boxes. Fewer cables. More autonomy. Here’s my open letter to Icom: oh8stn.org/blog/2026/02/17/icom-ic-705-if-i-were-i… #Icom #IC705 #IcomIC705

Grid-Down Emergency Communications is now available in print on Amazon. Focus: strategies, methods, and procedures for real grid-down comms. Soon also via PileupDX (Sweden) and DIY599 (Oliver DL4KA) in Germany.
This book focuses on the methods and strategies needed to keep your communications network working when the grid and normal infrastructure fail. It covers practical HF and VHF planning, fixed and field procedures, efficient data communications, power discipline, and group coordination, with the goal of giving you a reliable framework for real grid-down conditions.

Many amateur radio operators and those in the search and rescue community myself included use DJI drones in the United States. As far as I know, this video is the first one where a DJI representative speaks on the upcoming band of DJI products in the United States.
