The post warns against the use of QRO radio systems for off-grid or grid-down situations due to their high energy consumption. Instead, it advocates QRP radios, suggesting they offer greater efficiency and ease of use with renewable energy sources such as solar. The post also dismisses the idea of lowering the transmission power of QRO radios as a solution, arguing that it does not address issues with energy inefficiency and that such advice is misguided.

In May 2023, Julian OH8STN, Ed WQ2U, and Oliver DL4KA set off on an off-grid communications field test above the Arctic Circle. The team aims to test new strategies for off-grid communications, spanning portable power, robust hardware, and antenna efficiency. The expedition will take place near Rovaniemi, Finland. Also, part of the testing includes new robust packet radio capabilities and power supplies. The team encourages interaction from the community via Winlink and APRS messages.
