Reminder: Norddeutscher Rundfunk Christmas Eve Broadcast

“Greetings on board”: How to receive the broadcast

It has tradition and exudes a very special pre-Christmas mood: On Christmas Eve greetings are sent to the seafarers around the world from 8:05 pm – 10:00 pm and from 11:15 pm – midnight on NDR Info. And on the most different channels and technical ways, so that the greetings and messages can be guaranteed to be received on all seven seas.

The ship’s crews have several options to receive the program “Greeting on board”. Also the shortwave belongs to it.
The livestreams of the program (20.05 to 22 clock and 23.15 clock to 24 clock MEZ) can be found here: NDR Info and NDR Info Special. In addition, there is the possibility to listen to the program via the NDR radio app. NDR Info can also be received via FM, DAB + and DVB-S radio, NDR Info special only via DAB + and DVB-S radio.

So that all crew members on board – on the seas or in the harbors – can receive the traditional program, the NDR radio has also rented shortwave frequencies:

From 19:00 to 21:00 UTC (20:00 to 22:00 CET), the shortwave transmits over the following frequencies (UTC is the abbreviation for Universal Time Coordinated):

“Greeting on board” via shortwave

Frequency target area
6.080 kHz Atlantic – North
11,650 kHz Atlantic – South
9,800 kHz Atlantic / Indian Ocean (South Africa)
9,740 kHz Indian Ocean – West
9,570 kHz Indian Ocean – East
6.030 kHz Europe

Between 21:00 and 23:00 UTC (22:00 – 24:00 CET) the shortwave transmits over the following frequencies:

“Greeting on board” via shortwave

Frequency target area
6.145 kHz Atlantic – North
9,830 kHz Atlantic – South
9,590 kHz Atlantic / Indian Ocean (South Africa)
9,740 kHz Indian Ocean – West
9,675 kHz Indian Ocean – East
6.155 kHz Europe

NDR Info sends the “Greeting on board” from 20:05 to 22:00 CET. This is followed by the transmission of the Christmas Mass from the church of St. Mary Magdalene in Bochum-Wattenscheid from 22 to 23.15 CET. Then you will hear the second part of “Greetings on Board” until midnight CET.

Reminder: Christmas on-air event to honor Radio Luxembourg

Many thanks to SWLing Post contributor, Alexander (DL4NO), who writes:

For a very long time Radio Luxembourg was *the* pop music radio in Europe, especially in Germany and GB. At a time when Germany only had its public radio system, the Radio Luxembourg was the one and only. But this is history.

At Christmas, several German shortwave broadcasters, organized by Radio DARC, will transmit on 6070 kHz in memoriam of Radio Luxembourg from Vienna. See the attached flyer [above].

Excellent! Thank you for the heads-up, Alexander!

Christmas Carols from Antarctica on Shortwave

A program of Christmas carols will be broadcast from Antarctica on Christmas Eve. The transmissions on 7995 kHz USB will begin on December 23 at 2300 UTC, coordinated by McMurdo Communications Operations (MacOps) — known as “The Voice of Antarctica.”

Each year, the station’s residents celebrate the holiday by singing Christmas Carols to those at remote Antarctic field camps. Participation will be from stations scattered throughout the Antarctic continent.

“The radios and antenna systems are optimized for on-continent communication, so we will be lucky to hear them in other parts of the world, but it has happened in the past,” said Nathaniel Frissell, W2NAF, who is handling QSL requests and who has participated as part of the chorus in past years while studying in Antarctica. Frissell shared some links of previous concerts, one recorded at McMurdo Station and one from the University of Twente WebSDR in the Netherlands.

Video: “Tribute to a Century of Broadcasting”

Many thanks to SWLing Post contributor, Bill (WD9EQD), who writes:

You probably have already seen this, but from The ARRL Letter, November 21, 2019:

Art Donahue, W1AWX, of Franklin, Massachusetts, has posted his “Tribute to a Century of Broadcasting” video in recognition of the centennial of formal radio broadcasts. The video features a complete scan of the AM broadcast band (530 – 1700 kHz), with station IDs for all 118 AM radio channels.

Following is ARRL Link:

Radio Amateur’s “Tribute to a Century of Broadcasting” Video Debuts on YouTube

Following is YouTube link to the video:

It was a lot of fun to watch the video, hear the on-air id checks, and compare what he heard to the list of stations that I have heard.

Thanks for sharing this, Bill–I missed reading about this in the newsletter. This goes to show you that the AM dial is chock-full of stations here in North America. Those who complain that it’s “dead” simply aren’t listening.

Carlos seeks help identifying signals

Many thanks to SWLing Post contributor, Carlos Latuff, who writes:

Attached are two different recordings.
Both made in South Brazil.

– Florianópolis, 26/11/2019, 19h13 (Brasilia time) 12015 kHz

– Porto Alegre, 12/12/2019, 20h11 (Brasilia time) 7455 kHz

Searching on the Web I found these two frequencies related to US Navy NATO RTTY station STANAG 4481:

Are you able to confirm this?

Thanks for your inquiry, Carlos! Unfortunately, I cannot confirm this. If your radio had been in SSB mode, it would have made the RTTY pop out and we could have perhaps confirmed at least the RTTY mode with FLDIGI. I’m hoping a savvy SWLing Post reader can help you ID these transmissions. Please comment!

An Enigma machine just fetched over $106K at auction

(Source: Bloomberg.com)

A rare “Enigma” machine, used by Nazi Germany to create military communications code thought to be unbreakable, sold at auction for more than $106,000.

The 28.5-pound cipher machine went to an internet buyer on Saturday, according to Heritage Auctions. It comes with operating instructions, a case with an engraved Third Reich emblem — and a rich lore including how British scientist Alan Turing helped crack the code.

One of the unit’s 26 light bulbs is broken, according to the description.

It’s not the first time a Nazi code creator has traded hands for such a sum. In May, an Irish private collector swiped up a different encryption machine, known as the “Hitler mill” because of its hand crank, for 98,000 euros ($109,000) from a Munich auctioneer, according to the Telegraph.[…]

SWLing Post contributor and friend, Dan Robinson, and I once visited the National Cryptological Museum at Fort Meade and got to try our hand at using an Enigma machine. It’s an absolutely brilliant bit of mechanical engineering, of course. I highly recommend this museum to anyone interested in radio, computers or cryptography.
