A live, off-air, half-hour recording of the BBC World Service special Antarctic Midwinter Broadcast on 21 June 2025 beginning at 21:30 UTC. The broadcast, hosted by Cerys Matthews and which celebrated the 70th anniversary of the first BBC broadcast to Antarctica, featured messages and music for the members of the staff of the British Antarctic Survey (BAS) overwintering in Antarctica at the Rothera (Antarctic Peninsula) and King Edward Point and Bird Island (South Georgia) research stations. In addition to personal messages from family and friends, there was a message from Professor Dame Jane Francis, Director of BAS, who highlighted the construction of the Discovery Building at Rothera, and a very special message from King Charles III, a first for a monarch, highlighting climate change. He said "Each observation, measurement and calculation you undertake adds to the world's understanding of the Earth's fragile systems." The recording is of the transmission on 12065 kHz from the BBC's Woofferton, England, transmitting station. The broadcast was received by the Web-interface wideband software-defined radio at the University of Twente in Enschede, The Netherlands, with a "Mini-Whip" antenna in AM synchronous mode with 5.08 kHz RF filtering. Reception was quite good with little noise or fading and good signal strength. The additional parallel frequencies of 5960 kHz from Al'Dhabbaya, United Arab Emirates, and 9575 kHz from Ascension were heard but not as well as 12065 kHz.

Many thanks to SRAA contributor Tom Laskowski, who shares the following recording and notes: Broadcaster: All India Radio Starting time: 0100 Frequency: 10330 Reception location: South Bend, Indiana Receiver and antenna: Sony ICF-2001 Notes: One of the most enjoyable aspects of shortwave listening for me is the amazing variety of music that can be heard from all over the globe. I'm particularly interested in music from the Arab world and the Indian subcontinent. I recorded a large amount of music from All India Radio back in the early 2000s and compiled them into several recordings. AIR used to have a killer signal in our evenings on 10330 kHz and I recorded many hours of their programming. I've compiled nine (so far) music tapes from these recordings. I don't know the exact dates for these recordings.
