Reminder: Help record the 2018 BBC Antarctic Midwinter Broadcast today

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

UPDATE via Richard Langley:

Updated frequency list from BBCWS Audience Relations via World of Radio list:

5985 Woofferton 184°
7360 Ascension 207°
9890 Woofferton 182°

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).

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!

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.

Heil Sound and Last Man Standing

The following was posted through an email from Heil Sound:

When the producers of the popular TV show, “Last Man Standing,” needed an authentic ham radio set-up to use in the show, they turned to Heil Sound’s Amateur Radio Division, helmed by Bob Heil. Now, thanks to the generosity of the show’s star, Tim Allen, props from the show – including some autographed by Mr. Allen – are being offered for sale with all proceeds going to the Red Cross.

Today: National Radio Day

Many thanks to SWLing Post contributor, Tom Ally, who notes that today is National Radio Day:

About

National Radio Day is a time to honor one of the most longstanding electronic media and its role in our everyday lives. Radio delivers information, news, entertainment and company to millions of Americans every hour of every day. We invite listeners, broadcasters, producers and stations to celebrate on August 20.

History

Although there is not one authoritative source on the history of National Radio Day, it has been celebrated since the early 1990s on August 20. Perhaps it was decided that August 20 would be an appropriate day because 8MK (now WWJ) in Detroit, first broadcast on August 20, 1920.

According to Wikipedia, WWJ debuted as the “Detroit News Radiophone” and was “the outgrowth of interest in radio technology by the publishers of The Detroit News, combined with inventor Lee de Forest’s longtime promotion of radio broadcasting.”

Regular annual recognition didn’t quite take off until 2011 when NPR brought renewed attention to the day.

Now

National Radio Day is organized by Sabrina Roach, a Doer at Brown Paper Tickets, in partnership with non-commercial radio stations across the United States.

In July 2015, Roach called a meeting of radio broadcasters, producers and enthusiasts to discuss initiating a project to raise the visibility of non-commercial radio across the country. That effort put fresh energy behind the celebration of National Radio Day.

It’s also an ideal time to initiate a common project for full-power and low-power FM (LPFM) stations as hundreds of new LPFMs are getting on the air made possible by the Local Community Radio Act.

Solar Eclipse 2017: In the path of totality

A portion of the PARI campus

Tomorrow, we will be experiencing a total solar eclipse here in the mountains of western North Carolina.

Instead of enjoying the eclipse at home, I will be volunteering as a docent at the Pisgah Astronomical Research Institute in Rosman, North Carolina. Post readers might recall PARI as it was the location of our 2015 PARI DXpedition.

One of PARI’s 26 meter radio telescopes.

PARI is expecting at least 1,000 visitors tomorrow, from a number of countries. Many are scientists, astronomers, and guests who want to be in the path of totality.

On the PARI campus, we will be in totality for about 1 minutes, 47 seconds.

What makes the event truly special for PARI is that this is the first time in history a world-class radio astronomy observatory has been in the path of totality. To say the PARI astronomers are excited is simply an understatement. All four of PARI’s telescopes will be trained on our local star and gathering copious amounts of data.

If you don’t live in the path of the Eclipse, I invite you to check out PARI’s YouTube channel where they will host a live stream:

Gathering spectrum

I will also be gathering data of my own during the event.

I will remotely record the entire mediumwave (AM broadcast) band several hours before, during and after the eclipse. I will also set up a separate SDR to record either the 31/30 meter bands and my buddy, Vlado (N3CZ) is kindly using his SDRplay RSP1 to record from 6 MHz – 8 MHz.

What do I expect to see/hear in the spectrum recordings? Certainly a drop in noise. If I’m lucky, I also hope to hear some DX anomalies–hopefully a signal or two that I wouldn’t normally here in the middle of a summer day.

I don’t expect any dramatic results (though I would love to be proven otherwise!) since the ionosphere takes time to change states. My buddy Mike (K8RAT) likens it to an oven: it takes time for it to heat up to the desired temperature, and it takes time for it to cool down as well. I’m not so sure the shadow of the moon, which moves at a good clip, will be persistent enough to change the state of the ionosphere in any meaningful way.

If it does, I’ll be there to record it!

There are many other radio related experiments happening during the solar eclipse. A notable one that you can even help with is the 2017 Ham Radio Eclipse Experiment.

SWLing Post contributor, Dan Srebnick also suggests a few stations you might try catching on the AM broadcast band. Dan notes:

Something to do during the solar eclipse on Monday. There are 13 clear channel AM stations along the path of totality. Give a listen for them:

Kudos to Bob WB4APR (of APRS fame) for producing this list.

Post readers: Will you be in the path of totality or do you plan to enjoy a partial eclipse? Have you ever experienced a total solar eclipse?  What are your plans if any? Please comment!

August 28: BBC Atlantic Relay station special DRM broadcasts

RNZI-DRM-2(Source: DRM Consortium)

DRM will be part of a big anniversary on a small island in the Atlantic Ocean. On 28th of August at 1155 GMT Babcock International will ensure a special BBC digital transmission on 21715 kHz from the BBC Atlantic Relay station, marking the fiftieth anniversary of the BBC’s first short-wave radio broadcast from Ascension Island.

Since 1966, the Atlantic Relay station has broadcast BBC World Service programmes to Africa and South America, and to this day, continues to broadcast over 250 programme hours every week to East and West Africa in English, French, Hausa and Somali.

BBCRelayStation-Ascension IslandThe two hour-transmission on 21715 kHz will start with the old, special sound of Bow Church Bell in east London, the sound of which, even if in DRM this time,  will remind older listeners of the BBC broadcasts of many decades ago. The 21-hour transmission will be the regular BBC programmes for West and South Africa and will end at 1400.

DRM – Digital Radio Mondiale, is an international digital radio standard designed by broadcasters, for broadcasters, in co-operation with transmitter and receiver manufacturers. DRM is a high quality digital replacement for analogue radio broadcasting in the AM and FM bands.

This special transmission will be sent with greetings from Ascension Island’s BBC and Babcock International staff and visitors, who will be celebrating half a century of sterling broadcasting on August 28th.
