Help record the 2018 BBC Antarctic Midwinter Broadcast

Every year, the BBC broadcasts a special program to the scientists and support staff in the British Antarctic Survey Team. The BBC plays music requests and sends special messages to the small team of 40+ located at various Antarctic research stations. Each year, the thirty minute show is guaranteed to be quirky, nostalgic, and certainly a DX-worthy catch!

After successful listener events from years past, I’m calling on all SWLing Post readers and shortwave radio listeners to make a short recording (say, 30-60 seconds) of the BBC Antarctic Midwinter Broadcast today and share it here at the Post (frequencies and time below).

The recording can be audio-only, or even a video taken from any recording device or smart phone. It would be helpful to have a description and/or photo of your listening environment and location, if possible.

Audio should be in the MP3 format and videos either hosted on YouTube or Vimeo so that I can easily embed them without having to convert and upload myself.

If you submit your recording to me, I will post it here on the SWLing Post–and insure that the British Antarctic Survey receives the post, too.  The recordings will be arranged by geographic location.

Frequencies

This year, there have been few details about the broadcast announced in advance–I’ve seen no test broadcast announcements as in years past–so my fingers are crossed that it’ll take place on the air, on schedule.

Please note that the broadcast begins at 2130 UTC on (Thursday) June 21, 2018. The following frequencies were provided by Mauno Ritola who sourced them from a German SWL list serve:

From ASCENSION

7360 kHz

From DHABAYYA

6035 kHz

From WOOFFERTON

7230 and possibly 5985 kHz

I’m sure there will be live reports in the SWLing Post chat room during the broadcast.  Please sign in and share your report as well!

I hope I’ll be able to receive the broadcast this year–I’m traveling again, but will have a receiver in tow. Worse case, I’ll snag the broadcast from a WebSDR in Europe (which is a pretty easy catch).

Listening for the Midwinter test transmissions last week with the Elecraft KX2.

The Midwinter broadcast is one of my favorite programs of the year. I suppose, in part, this is because it happens on June 21–the Summer/Winter solstice–which also happens to be my birthday! Woo hoo!

North Korea Summit: Voice of Korea English language shortwave frequencies

Many thanks to SWLing Post contributor, DanH, who writes:

I recorded and edited clips from two Voice of Korea SW broadcasts in English at different times earlier today (UTC). The radio clock in this video is fairly accurate and is set to UTC. The VOK announcer reads a list of VOK English language broadcast times and frequencies near the end of the video. Happy listening! Propagation conditions aren’t that bad.

Armed Forces Day Crossband Test on May 12, 2018

Many thanks to SWLing Post contributor, Brian (W9IND), who shares the following announcement regarding the next Armed Forces Day Crossband Test:

The Army Military Auxiliary Radio System will host this year’s Armed Forces Day Crossband Test, scheduled for May 12, 2018. This annual event is open to all radio operators, and will not impact any public or private communications. For more than 50 years, military and amateur stations have taken part in this event, which is only an exercise scenario, designed to include hobbyist and government radio operators alike.

The AFD Crossband Test is a unique opportunity to test two-way communications between military communicators and radio stations in the Amateur Radio Service (ARS), as authorized in 47 CFR 97.111. These tests provide opportunities and challenges for radio operators to demonstrate individual technical skills in a tightly-controlled exercise scenario that does not impact any public or private communications.

Military stations will transmit on selected military frequencies and will announce the specific ARS frequencies monitored. All times are ZULU (Z), and all frequencies are Upper Side Band (USB) unless otherwise noted. The frequencies used for the test will not impact any public or private communications, and will not stray outside the confines of the exercise.

The following stations will be making two way radiotelephone contacts with stations in the ARS between the time periods listed on the frequencies listed in kilohertz below. WAR, WUG-2 and NSS will also make CW contacts.
