Two live, off-air, half-hour recordings of the BBC World Service special Antarctic Midwinter Broadcast on 21 June 2017 beginning at 21:30 UTC. The broadcast features special messages and music for the staff of the British Antarctic Survey overwintering in Antarctica.

The first recording is of the transmission on a frequency of 7360 kHz from the BBC's Ascension Island relay station (250 kW transmitter power, antenna beam 207 degrees). The transmission was received on a Tecsun PL-880 receiver with a Tecsun AN-03L 7-metre wire antenna in Hanwell (just outside Fredericton), New Brunswick, Canada, in AM mode with 5 kHz RF filtering. Reception was fairly good with some atmospheric noise.

The second recording is of the transmission on a frequency of 5985 kHz from the BBC's Woofferton, England, transmitting station (300 kW transmitter power, antenna beam 184 degrees). 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 USB mode (to avoid potential adjacent-channel interference) with 2.40 kHz RF filtering. Reception of the broadcast was very good with occasional atmospheric noise.

The program started very slightly late for both transmissions with the first or first two words ("This is") missing.

2016 BBC Antarctic Midwinter Broadcast: June 21, 2016

Many thanks to SRAA contributor, Mark Hist, who notes the following:

Thanks for alerting shortwave listeners to the British Antarctic Survey broadcast. It felt very poignant listening to a broadcast aimed at such a small number of people, with the voices of their loved ones being launched around the world.

I was able to record the broadcast from only 100 miles away from the Woofferton transmitter, so needless to say the quality and strength was very good. I imagine hearing that broadcast buried in the noise from far away with those happy birthday songs and best wishes must have been very emotional for its intended audience.

I enclose a short segment from my 30 minute recording, plus a photo (above) taken the next day of my set up (it was dark at the time of the recording).

I also recorded the broadcast from Saint-Anne-de-Beaupré, Québec, Canada. I wrote a post about this on the SWLing Post (click here to read). The following is my recording from 7360 kHz. Reception was not nearly as strong as that of Mark, above:

Reception was good with some atmospheric noise. The interruption in the audio around the 11-minute mark was due to a check of other parallel frequencies.

The second recording is of the transmission on a frequency of 5985 kHz from the BBC's Woofferton, England, transmitting station (300 kW transmitter power, antenna beam 184 degrees). 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 mode with 5.17 kHz RF filtering. Reception of the broadcast was good with some noise cracks.
