As the FIFA World Cup Tournament begins its matches in North American cities starting Thursday, June 11th, hams in the stadiums’ 16 host cities -- in Canada, the United States and Mexico – will be calling CQ for Football/Futbol on the Air.

They will be using 1x1 callsigns and operating CW, SSB and the digital modes on the HF bands. Teams in each host city will be active on the days the matches are played there. Listen for callsigns, such as W1C, W2C, K0C, K4C, among others – for US call areas – and VC3F and VB7F for Canada. The three stations in Mexico are 4A1MTY, 4A1GDL and 4A1CMX.

The tournament kicks off with the first match in Mexico City on June 11. The final match will take place in the New York/New Jersey host stadium on July 19th. Find additional details on the website http://www.wc2026ses.org or email info@wc2026ses.org

The amateur radio event is not affiliated with the World Cup but has been organised in support of the tournament, which has 48 teams, the largest number of teams in the tournament’s history.

The following is a message from SafecomLink:

SafecomLink has published a new case study documenting live AI-based weather routing over HF radio north of the Arctic Circle. Sailor Harley Soltes (LA/KN7H) used SafecomLink with a Pactor 4 link to access the Safie AI assistant from his vessel off the Norwegian coast — establishing a connection to a land station in Austria (OE3FQU) on 14.120 MHz, then reaching the open internet, with no cellular coverage, no satellite service, and no shore-side infrastructure.

The real-time two-way AI conversation provided wind forecasts and a day-by-day crossing comparison for the passage to Lofoten, Norway. After completing the passage, Soltes reported the AI forecast was more accurate than his usual weather apps and far faster than the WinLink email method he previously used.

This is pretty game-changing — to have fast Pactor 4 communication from sea to a real-time internet AI connection. — Harley Soltes, LA/KN7H
