Cross-training builds real resilience. This weekend combined HF communications, fieldcraft, and marksmanship in the swamps of Puolanka, Finland—proving that preparedness isn’t theory, it’s practice.
By now most of us would agree that the Lab599 TX-500MP is the Ultimate rugged field radio. In this blog/video, I’ll show you my very first Winlink session using this preparedness-minded HF Radio.
A field-proven look at wireless data communications using the Icom IC-705 and Microsoft Surface Go—now revisited in light of the newly released Yaesu FTX-1. Compare features, and true cable-free operation for modern ham radio in the field.
A field-tested look at the Emergency Winlink Gateway—an off-grid, low-power HF email system built for rapid deployment during real-world disasters.

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.
When discussing efficient low power communications, it is impossible to deny the effectiveness of narrow bandwidth data, even at low power levels. But wait, there’s […]
