Biggest solar storm in 20 years hits Earth

This week, the most severe solar radiation storm in 20 years has created challenges for the Ham Radio community.

It began on Monday 19th January 2026, arriving at Earth 36 hours later, and its effect was expected to last much of the week. The National Weather Service declared the storm to be at an S4 level - a degree of severity not seen since October of 2023. S4 is the second-highest level of this type of storm.

The storm's severity, which exceeded that of the one in October of 2023, disrupted the HF bands, challenging ham radio operators, while creating spectacular auroral displays.

Can Ham Radio Help Taiwan Survive?

In Taiwan, a nonprofit civil defence group, Ganghu, has started training people on how to communicate using amateur radio, also known as ham radio, if the internet is unavailable. This comes as Beijing, which claims democratically self-governed Taiwan as its own territory, faces allegations of sabotaging and damaging Taiwan’s undersea internet cables.

Taiwan currently relies on 15 international and 10 domestic communication cables to carry more than 90% of its internet traffic. Without these, the island could be cut off from the outside world, and even internal communications would likely collapse.

These internet cables, often described as the island's "digital lifelines," are damaged an average of seven to eight times a year, according to a 2025 report by Taiwan's National Security Bureau. 

As authorities scramble to protect cables and build satellite-based backup systems, some citizens are turning to amateur radio as a solution.

Important changes to the RSGB QSL Service

The RSGB is pleased to announce the next stage in developing its QSL Bureau Services following the retirement of the RSGB QSL Bureau Manager Richard Constantine, G3UGF.

After a comprehensive review of long-term options, the Society has entered into a formal Contractual Agreement with the German National Radio Society, Deutscher Amateur Radio Club, to process all incoming and outgoing RSGB QSL cards.

DARC operates a modern, high-capacity QSL bureau. Its systems already support a number of national societies and offer industrial-scale reliability, digital processing capability and long-term resilience.

This partnership will provide a robust and effective QSL bureau service for RSGB members. Volunteers remain central to the RSGB QSL Bureau Service and the RSGB extends its thanks to all sub-managers, whose dedication forms the backbone of the service.

The new arrangements are designed to support volunteer involvement, not replace it, and to ensure volunteers have a strong infrastructure behind them. The new service preserves the traditional bureau structure but will offer additional options for RSGB members who send cards.
