Chris’ 2016 Pirate Radio Year in Review

Many thanks to Chris Smolinski who has, once again, crunched the numbers to give us a look at HF pirate radio activity in 2016.

[…]To gauge shortwave pirate radio activity in 2016, I analyzed the Shortwave Pirate loggings forum of the HF Underground (http://www.hfunderground.com). A computer script parsed the message thread titles, as well as the timestamps of the messages. This information was used to produce some statistics about the level of pirate radio activity. Of course, as Mark Twain has written: “There are three kinds of lies: lies, damned lies, and statistics.” Still, let’s see what we can learn.

There were 13,860 messages posted to 2,398 unique threads, compared to 13,944 messages posted to 2,183 unique threads in 2015. Activity levels are essentially flat, but still at historically high levels. Back in the 1990s, it was not uncommon for an entire month to go by with only a handful of pirate stations logged. If you want to know when the “golden age” of shortwave pirate radio was, I would say it is right now.[…]

Chris has posted his full analysis on RadioHobbyist.org.

As you can tell from Chris table at the top of this page, January is a very active month for HF pirates. If you’ve never chased pirate radio stations, check out our pirate radio primer. Pirate radio DXing is incredibly fun!

DSWCI archives now online

Many thanks to SWLing Post contributor, Harald Kuhl, who shares the following message sent by Anker Petersen of the The Danish Shortwave Club International (DSWCI):

Dear DSWCI members.

In a few hours the DSWCI exists no longer.

But our webmaster Rolf Wernli has done a tremendous job between Christmas and New Year by changing our wellknown website to an electronic archive with good reading for all members !

If our former website appears, it is because it has been saved in your computer.

Please type www.dswci.org, press Enter and the new website should appear.

Enjoy and have a Happy New Year!

Best 73,

Anker

What a brilliant resource! Thank you, Harald, for passing this information along and many thanks to the fine folks at the DSWCI for sharing their archives with the radio community!

The SWLing Post: 3,000 posts and counting!

SWLingPost-DXFiend-Vintage-FrontA couple of weeks ago, I noticed that we had crossed a small milestone here on the SWLing Post: as of this post, there are now 3,067 (!!!) published posts in our archives.

I simply can’t believe we’ve surpassed 3,000 posts–especially knowing we only passed 2,000 posts September of 2015.

People can say what they will about our shortwave hobby’s future, but I’m here to tell you that  interest in is far from dead. Indeed, it is dynamic, alive and well!

This morning, I took a look at our web statistics via Google Analytics for the month of December 2016 (not including today).

It’s hard for me to believe we’re averaging about 6,790 daily pageviews!

And the secret sauce in surpassing 3,000 posts and healthy numbers? Our amazing contributors!

Thank you so very much!

As I’ve mentioned before, I had no aspirations for the SWLing Post to become a popular destination for shortwave and amateur radio enthusiasts; it was mainly a site where I could jot down things I found of interest to me and keep tabs on the radio and international broadcasting industry. I was simply making my bookmarks and thoughts public, perhaps a little in advance of the social media outlets that now exist for shortwave radio and related topics.

As we move into 2017, I’d like to thank you all for reading and contributing to the SWLing Post community!

Happy New Year, radio friends!

Looking at HF OTH RADAR

Many thanks to SWLing Post contributor, Trevor, who shares this link to a blog post from Daniel Estevez describing the characteristics of HF OTH RADAR:

Most amateur operators are familiar with over-the-horizon radars in the HF bands. They sometimes pop up in the Amateur bands, rendering several tens of kilohertzs unusable. Inspired by Balint Seeber’s talk in GRCon16, I’ve decided to learn more about radars. Here I look at a typical OTH radar, presumably of Russian origin. It was recorded at my station around 20:00UTC on 8 December at a frequency around 6860kHz. This radar sometimes appears inside the 40m Amateur band as well.

Above this post you can see a waterfall plot of the radar signal. It’s the wide red signal. It is 15kHz wide and pretty strong, but severely affected by frequency-selective fading. Looking at the IQ recording in Audacity, it is clear that the radar uses pulses with a 50Hz repetition rate. This explains the characteristic sound of this radar when received with a conventional SSB radio. It sounds similar to AC hum (here in Europe, of course).

Video: Gary DeBock’s “Baby FSL” antenna

Many thanks to SWLing Post contributor, Gary DeBock (N7EKX), who shares this video and notes the following on YouTube:

This is the new 3.5 inch (89mm) “Baby FSL” antenna, designed to provide a powerful DXing gain boost for Ultralight radios (or any other portables) despite its very small size. It has 32 Russian surplus 140mm x 8mm ferrite rods and 31 turns of 1162/46 Litz wire. In the demonstration video it provides a daytime DX gain boost for 750-KXTG (Tigard, Oregon, 50 kW at 160 miles) from inaudible up to about S7 on the Eton Traveler III Ultralight radio.

Click here to view on YouTube.

Gary is certainly a first-rate DXer and an ambassador of our radio hobby. Gary shows us here that, with a little ingenuity, we can take a $50 radio and turn it into something exceptional! Homebrewing at its best.  Thank you, Gary!

Also, I had never considered that a high-gain FSL antenna would require very precise placement of the receiver for proper inductive coupling. It makes sense, though. This loop is tuned for razor-sharp precision!

Some day, when I have a little free time, I’m going to build one of Gary’s FSL designs.

Leap second added to 2016

(Source: NPR)

Here’s a timely reminder for all you would-be revelers out there: Be careful with your countdowns this New Year’s Eve. There will be a little extra time to bask in the glow of a retreating 2016 — or curse its name, as the case may be.

Whatever your inclination may be, one thing is certain: Before the year is out, the world’s foremost authority on time will be adding one more second to the clock.

In a bulletin released this summer, the International Earth Rotation and Reference Systems Service, or IERS, said it would be necessary to introduce a “leap second” at the end of December. Timekeepers use this added second much as leap years are used — to bring the world’s atomic clocks in sync with the Earth’s own distinctive rhythm, which in this case is determined by its rotation.

This leap second isn’t the first. Since 1971, the world has added leap seconds with some regularity — typically every two to three years — and the latest leap second was added only last year, in June.

Last year, I recorded the 2015 Leap Second via WWV–click here to read that post. Though such a subtle change, it is fun to hear that extra second added. I plan to record the full 31 meter band New Year’s Eve–hopefully, I’ll also catch the 10,000 kHz WWV Leap Second!

WRTH 2017: A look inside

I received my copy of the 2017 World Radio and TV Handbook (WRTH) directly from the publisher last week, just prior to Christmas holiday ravels. As I mention every year, I look forward to receiving this excellent staple radio reference guide–and this is their 71st edition!

WRTH’s team of noted DXers from around the world curate frequencies and broadcaster information by region; while I’m not sure how they orchestrate all of this, the end result is truly a symphony of radio information. In addition to broadcaster listings, WRTH’s radio reviews, feature articles, and annual HF report make for excellent reading.

But the WRTH isn’t just a frequency guide: the publication always devotes the first sixty or so pages to articles relating to various aspects of the radio hobby. Following, I offer a quick overview of these.

The first article always features a WRTH contributor:  this year, WRTH’s International Editor, Sean Gilbert, tells us what sparked his interested in the hobby and what lead to his career with WRTH which started in 2000.

The second set of articles is always my favorite: WRTH receiver reviews.

This year, WRTH begins with a review of the Icom IC-7300 general coverage transceiver.  They also review the Reuter Elektronik RDR55D, and re-visit the SDRplay RSP1. Following radio reviews, they evaluate the excellent Wellbrook ALA1530LNP magnetic loop antenna and the Bonito AAS300 3 way active RF splitter.

The following article focuses on one of my favorite shortwave broadcasters, The Mighty KBC. WRTH contributor, Max van Arnhem traces the broadcaster’s history and gives us a little insight about the people behind this music powerhouse. If you’re a KBC fan, you’re in for a treat!

I was very happy to find that the following feature article explores the world of Remote Reception. No doubt, remote listening is becoming one the most accessible ways many of us discover and enjoy our hobby today–especially as it can be difficult for some of us to fight urban radio interference.

Following this, WRTH writer, Hans Johnson, features an article on CKZN St. John’s Newfoundland.  In this short article, Johnson covers the history and mission of this shortwave relay, dating back to the days when Newfoundland was a British dominion. Looking forward, Johnson notes that the CBC intend to not only continue this service directed at Labrador’s most remote areas, but it intends to replace their 1 kW Elcom Bauer transmitter in the coming years. This pleases me to no end as I’ve always loved snagging this particular relay of CFGB from my home here in North Carolina.

Next, DXer Rob Shepard writes about his travels in South America and the Pacific. Being an avid traveller myself, I love reading about others’ adventures across the globe with radio. Shepard even notes some catches from the Queen Mary II. I’ve never had the chance to do DXing while maritime mobile, but I hope to someday.

The following article features Danish radio enthusiast, Vagn Fentz, who has collaborated with WRTH since one of its very first editions. His radio history starts back when he was a schoolboy in Denmark during WWII, listening to the radio in secret. His story gives us insight into both his own world and that of the WRTH over the years.

Next, Michael Pütz outlines the progress, so far, of setting up an HF disaster relief radio network: the IRDR Project. If you haven’t heard of the IRDR project, this article makes for a great primer and also speaks to the potential future of a radio network that could have major positive impact over vast regions in the wake of disaster.

The final article–a tradition–is the WRTH  HF propagation report/forecast by Ulf-Peter Hoppe. Always an informative read (despite the fact we’re heading into a solar minimum).

The 71st is another fantastic edition of the World Radio TV Handbook. I’ve never been disappointed with WRTH, in truth. Their publishing standards are such that the quality of their reviews, their writing, and (most importantly) their broadcast listings are simply unparalleled.

For DXers who collect QSL cards, you’ll find that broadcaster contact information in WRTH is often more up-to-date than a broadcaster’s own website. When readers contact me asking for QSL information from an obscure broadcaster, the first place I search is the current WRTH. Remember: their information is based on volunteer contributors who specialize in specific regions of the world–the most knowledgeable regional DXers keep this publication accurate.

Purchase your copy of WRTH 2017 directly from WRTH’s publishers, or from a distributor like Universal Radio (US) and Amazon.com (US), Radio HF (Canada), or BookDepository.com (International).
