Hang on a second…seriously

WWV-TimeCodeGenerator

One of four WWV time code generators in late August, 2014

Tonight, for the first time in three years, we will experience a leap second. What is a leap second?  Wikipedia provides a concise explanation:

A leap second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC) in order to keep its time of day close to the mean solar time, or UT1. Without such a correction, time reckoned by Earth’s rotation drifts away from atomic time because of irregularities in the Earth’s rate of rotation. Since this system of correction was implemented in 1972, 25 such leap seconds have been inserted. The most recent one happened on June 30, 2012 at 23:59:60 UTC. A leap second, the 26th, will again be inserted at the end of June 30, 2015 at 23:59:60 UTC.

Like many of you, when I think of time–or UTC–I think about the NIST radio station WWV in Fort Collins, Colorado.

I had the honor of visiting the facility last year (yes, photo tour still forthcoming!).  During the tour, my guide and Chief Engineer at WWV and WWVB, Matthew Deutch, told me that he’s always going to be on site come Leap Second!

I wrote Matt this morning to ask what were his plans tonight?  His reply:

“The leap second happens at 0000 UTC tonight, which is 6:00 pm here in Fort Collins. All of the programming took place at the beginning of the month, so the equipment is armed…we just sit back and watch for the leap this evening.

Even though it is automated I hang around the station to make sure everything goes smoothly at the critical moment…”

WWV-First-Sign-SMMatthew closed his message by wishing me a “Happy Leap Second.”

Back at you, Matt! We hope that second leaps as smoothly as you’d like!

Not to put Matt on the spot, but you can listen to WWV (or the atomic clock of your choice) make the leap second tonight at 00:00 UTC. As for me, I’ll hop on 10 MHz and 15 MHz to hear (and hopefully record) the extra “tick.” At the end of this post, I’ve provided a list of time stations for your convenience.

Happy Leap Second!

Shortwave Radio Recordings: Voice of Greece

greeceFor your listening pleasure: the Voice of Greece.

This was recorded on 29 June 2015 starting around 01:50 UTC on  9,420 kHz using my WinRadio Excalibur and my horizontal delta loop external (wire) antenna.

I’m very pleased with this off-air recording because it contains several minutes of multi-language station IDs in the last 10 minutes or so of the broadcast.

A map of languages

MapOfLanguages

(Source: IFLScience)

This beautifully illustrated infographic (above), designed by South China Morning Post’s graphics director Alberto Lucas Lopéz, shows the most spoken known languages in the world and where they’re spoken by the 6.3 billion people included in the study.

Based on records collated from the database Ethnologue, the infographic illustrates the wide-ranging facts and figures of the world’s living languages catalogued since 1951.

“There are at least 7,102 known languages alive in the world today. Twenty-three of these languages are a mother tongue for more than 50 million people. The 23 languages make up the native tongue of 4.1 billion people,” says Lopez on his infographic.

“We represent each language within black borders and then provide the numbers of native speakers (in millions) by country. The colour of these countries shows how languages have taken root in many different regions,” added Lopez.

You can see the full pie chart in all its technicolor glory here.

International Radio Serbia petition

SerbiaProtestMany thanks to SWLing Post reader, David Iurescia (LW4DAF), who shares a link to this online petition for International Radio Serbia.

The link labeled, “Serbia needs a World Service” is prominent on Radio Serbia’s website.

Click here to open the petition page which is in both Serbian and English. I have pasted the English wording of the petition below:


Serbia needs a world service!

The friends and listeners of the International Radio Serbia – Radio Yugoslavia have initiated this petition to prevent the extinguishing of this media house, important for Serbia. The people signed below ask of the Serbian Prime Minister to abolish the government’s decision and that he personally talks to the employees. We demand that the extinguishing of this radio be stopped and that Serbia finally starts pondering its presence among the global media and the importance of shortwave broadcasting, along with all other media outlets that the International Radio Serbia is using (internet, video and audio newscasts, live stream).

After the failed negotiations between the employees of the International Radio Serbia – Radio Yugoslavia and the Ministry of Culture and Information, the Serbian Government passed the decision to EXTINGUISH the International Radio Serbia as of 1 July 2015.

The Serbian Government (including several different ruling parties and governments since the country has not been called Yugoslavia) for more than two decades is unable to understand the significance of having a media house such as the International Radio Serbia. It is owing to the negligence of the Serbian Government that we still carry the name Radio Yugoslavia.

The International Radio Serbia is the only radio station in the country that broadcasts program on the shortwave frequency, reaching all parts of the world, and for 79 years has been the promoter of the state policies, economy, culture, and traditions. Through the broadcasts on the short waves and via internet (www.glassrbije.org and www.voiceofserbia.org ) in Serbia and another eleven languages, this media house has been the unofficial portal of the state of Serbia for eight decades, covering all five continents. This kind of informal diplomacy is today an irreplaceable avenue of country’s promotion in the most positive manner. It is confirmed by the fact that other, much bigger countries, have not renounced on their world services, so they are modernizing and improving the work of similar media – Deutsche Welle, BBC World Service, Voice of America, Voice of Russia – as do some countries in the region, like Slovenia, an EU member that declared their radio for the media of national importance.

Numerous listeners around the world, as well as the Serbian embassies abroad and foreign embassies in Serbia, have assessed the International Radio Serbia as a relevant and reliable source of information about Serbia. For the members of Serbian Diaspora, it is an irreplaceable tie with the homeland.

It is worth reminding that the International Radio Serbia is one of the oldest shortwave radio stations, founded six years before the Voice of America. It started broadcasting on 8 March 1936, in the then Kingdom of Yugoslavia.

It’s Field Day weekend: find a local event, have fun

FieldDay2015If you live in North America and have an interest in becoming a ham radio operator, this is the weekend to check out what amateur radio is all about, and meet local radio enthusiasts.  It’s Field Day.

What is Field Day?  I’ll quote from the ARRL, who sponsors the event:

“ARRL Field Day is the single most popular on-the-air event held annually in the US and Canada. On the fourth weekend of June of each year, more than 35,000 radio amateurs gather with their clubs, groups or simply with friends to operate from remote locations.

Field Day is a picnic, a camp out, practice for emergencies, an informal contest and, most of all, FUN!

It is a time where many aspects of Amateur Radio come together to highlight our many roles. While some will treat it as a contest, other groups use the opportunity to practice their emergency response capabilities. It is an excellent opportunity to demonstrate Amateur Radio to the organizations that Amateur Radio might serve in an emergency, as well as the general public. For many clubs, ARRL Field Day is one of the highlights of their annual calendar.

The contest part is simply to contact as many other stations as possible and to learn to operate our radio gear in abnormal situations and less than optimal conditions.”

GOTAMany Field Day sites have a GOTA (Get On The Air) station where non-licensed individuals are welcome to play radio. It’s a fantastic way to try your hand at transmitting with a little guidance and encouragement from the more experienced. Indeed, even if there is no GOTA station, you will often be invited to try out the mic.

You’ll find that ham radio operators are very welcoming on Field Day–after all, spreading the word about the fun of amateur radio is what it’s all about. Indeed, I’ve shown up unannounced to a number of Field Days over the years; once I even got some serious radio time with the Charlotteville Amateur Radio Club while on vacation in Prince Edward Island, Canada.

Keep in mind that there are many shortwave listeners among the amateur radio community; indeed, many hams became interested in the hobby through SWLing.

The ARRL has made it quite easy to find registered Field Day locations in your region. Click here to find a local Field Day event near you–and have a great Field Day!
