BBC Midwinter Broadcast to Antarctica: June 21, 2026

This is the BBC Midwinter Broadcast to Antarctica recorded on June 21, 2026 at 09:30 UTC in Foulden, Scotland, UK. The radio was an Elecraft KX2 connected to a 31-foot 9:1 random wire antenna in the back garden. The broadcast starts on 9460 kHz, but I then move to 12070 kHz because it had slightly less local noise.

Personal note

The BBC Midwinter Broadcast remains one of my favorite SWLing events of the year. I simply love the idea that the BBC would broadcast from two different sites on three different frequencies via shortwave to a relatively small audience of British Antarctic Survey scientists wintering over in Antarctica.

It's always a joy to listen live, knowing that they're celebrating midwinter with parties at their stations and hearing the voices, messages, laughter, and well-wishes of loved ones carried to them over the air by shortwave radio.

In an age of instant communications, there's still something magical about that.
