Residents of Nigeria’s north-east have lived in isolation for two years. Terrorists frequently target phone lines in order to cut off communication. Traders avoid the region. Journalists live under threat.
But a new radio programme is now bringing important information to three states – Borno, Adamawa and Yobe – which have been under a state of emergency since May 2013 and turned by the army into a battleground against Islamist terrorist group Boko Haram.
[…]Most radio stations in north-eastern Nigeria are government-owned and broadcast in Hausa or English. For the tens of thousands of Kanuri-speaking people, there is no independent source of information, only state-sanctioned news and Boko Haram propaganda.
“Boko Haram controls people by inducing fear. Without alternatives, people are very much under the influence of Boko Haram’s propaganda,” says Wada. “Through Dandal Kura, we try to work against the propaganda by giving listeners objective information.”
Dandal Kura, which means “the big hall” in Kanuri, was initially set up in January as a three-month pilot project funded by United States development agency USAID. Since April, the programme is managed and run by Freedom Radio, a private broadcaster based in Kano.
[…]What is special about Dandal Kura is not only the language. The programme is transmitted by shortwave, on 9940 kHz, instead of the commonly used FM frequency band.
Shortwave is especially important in rural areas across Africa where FM waves hardly reach, but shortwave radios are easily available for an affordable price. In northern Nigeria they can be bought at any marketplace for about 600 Naira (3 dollars).
There is another key advantage: The shortwave transmission system is located hundreds of kilometres away – on the Atlantic island of Ascension – which means it cannot be destroyed by Boko Haram.
An FM transmitter, in contrast, would have to be installed on the ground in northern Nigeria.
“If we had set up FM transmitters, there would have been a high chance that Boko Haram would take them out,” says Smith, who has experience in setting up radio stations in African conflict zones, including Somalia and Central African Republic.
The CommRadio CR-1
While browsing the Universal Radio used equipment index during lunch, I noticed Universal currently has a used CommRadio CR-1 (not the CR-1a) for $379.95. In my opinion, that’s a brilliant price for a used CR-1 in good condition.
You can buy used gear with confidence from Universal Radio; they back their items with a 60 day warranty and have excellent customer service

In response to my recent post about the vintage Arvin 68R58 transistor radio, SWLing Post reader, James Patterson, has shared photos of his collection in New Zealand. James has captioned each photo below:
This portable Sanyo was bought at a “Second Hand” shop. It had badly corroded battery connections. I repaired it and it works fine now.

Very early National portable with twin speakers, broadcast [band] and [shortwave. Works very well.
This PYE Caddy was actually made here in New Zealand. I believe the design was from the UK though. It still works very well.
The PYE Caddy without the plastic cover.
Very popular in their day, the RED National Panasonic pocket AM Transistor 6. Works well.
Very early AIWA pocket Transistor 6. Still works well.
The “Murphy 8” Transistor radio. Broadcast band only. Wooden case in fab condition. Works very well.
This is the rear view of the “Murphy Transistor 8.” I gave it a new battery holder.
This is a “Murphy Transistor 7+” Im not sure what the “+” means because it does have only 7 transistors. Very good performer for its age. Wooden case is identical to the previous Murphy 8.
This is the rear view of the “Murphy Transistor 7 plus.” All very original, and works fine.
This National Panasonic DR 28 is not part of my early AM Transistor radio collection. It is, however, part of my shortwave radio collection.
Many thanks, James, for sharing photos from your collection! You certainly have some gems in there. I was not at all familiar with the New Zealand-made PYE Caddy, in fact. I’m curious if other radios were made in New Zealand in the past.
I bet you and I might agree that the Panasonic DR-28 (a.k.a. RF-2800 in North America) hardly feels “vintage,” but at 37 years old it certainly qualifies by most standards–hard to believe. The RF-2800 pops up on eBay quite often and has certainly held its value well. (Click here to search.)
Seeing the DR-28/RF-2800, in fact, is making me lust even more after the venerable Panasonic RF-2200! Alas…so many radios!

The following review originally appeared in the May 2015 issue of The Spectrum Monitor magazine.
It’s no secret…I’m a bit of an SDR geek. Yes, after discovering the power of software-defined radios a few years ago, I’m hooked: SDR listening represents nearly 95% of my home listening and monitoring. And I love it.
As a result, I’m always looking at new SDR technologies to note advances that could improve both my at-home and on-the-road listening––not to mention, satisfy my appetite for spectrum and broadcast recordings.
A few months ago, I heard about a new military-grade SDR called the TitanSDR. Being eager to check it out, I reached out to the Italy-based manufacturer, Enablia; they kindly lent me a TitanSDR Pro for review.

But here I must insert a disclaimer. Even though I love SDRs, I always find myself hesitating slightly when it comes to writing a review of one––simply because, when compared with tabletop and portable radios, SDRs tend to be so very complex. While I’m fairly well versed in what to expect of an SDR application, the learning curve (and sometimes even installation curve) can be formidable. And the TitanSDR seemed especially daunting: since it’s designed for heavy, full-duty, multi-channel SIGNET and military use, I expected to need a at least a few days to both install the device and, more significantly, to learn the ropes of the application which drives the SDR.
Fortunately, my fears were unfounded. The TitanSDR and I were in sync almost before I knew it, hinting favorably about an accessible user interface.
The TitanSDR ships in a box with the following components: the Titan SDR “black box” receiver, a TitanSDR installation DVD, a printed installation manual, a USB memory stick with a license key, USB cable with chokes on both ends, and a separate regulated power supply.
Not purely a plug-and-play device, the TitanSDR requires a proper three-step installation. Fortunately, the installation manual walks you through the process, which is actually quite simple. Within a mere five minutes, I had the TitanSDR installed and on the air.
The application which runs an SDR is your interface to all of the radio’s capabilities. A top-notch SDR paired with a confusing SDR application will greatly diminish usability and, frankly, sheer enjoyment.
Fortunately, this is where the TitanSDR comes up trumps. To be clear: the TitanSDR has one of the best user interfaces of any SDR I’ve ever tested. While SDR interfaces are subjectively evaluated––some prefer a more dense, involved GUI––I always appreciate simplicity and overall usability over lots of (visible) bells and whistles.

I’m especially impressed with how easily the TitanSDR app is designed to cope with multiple band windows, both wide and narrow, while many SDR manufacturers struggle with making an intuitive interface for merely one wideband and one narrowband window, each.
The user interface is divided into three major components: the panoramic scope, the wideband scope, and the narrowband scope. Let’s take a look at each.
Panoramic Scope
TitanSDR Panoramic Scope. Click to enlarge.
When you first open the Titan application and connect the SDR, the panoramic display, which spans the top of the window, comes to life. If hooked up to an antenna, you’ll see spectrum peaks across the display, but you’ll hear no audio because you must first select a wideband and then a narrowband window.
Wideband Scope
At the upper left portion of the panoramic scope, you’ll find a button that allows you to add a wideband selection/channel. After clicking the “add” button, you’ll need to choose the width of your wideband slice. Your choices:
After selecting your wideband width, the wideband scope will appear with the spectrum and waterfall in action. At this point, you’ll still hear no audio, but you’ll see a wideband swatch of frequency represented by your selection.
New wideband selections default with a beginning frequency of 0 kHz. To place the wideband selection into the part of the shortwave spectrum you want to hear or record, you simply click and drag the appropriately colored wideband swatch within the panoramic display to the part of the HF spectrum you wish to monitor.
Selecting a Wideband channel size. Click to enlarge.
Your first wideband selection is labeled in red, the second in green, third in blue, fourth in purple. While there are limits to the number of wideband selections you can make, based on the total bandwidth of your selections [the TitanSDR owner’s manual provides a matrix of possible combinations], each is readily identifiable by color in the panoramic display.
After you’ve created a wideband selection and placed it where you’d like to listen, you’ll now need to make a narrowband selection in order to begin tuning and listening.
Narrowband Scope
Creating a narrowband channel is similar to creating a wideband channel: at the top of the wideband scope window, simply click on the “add” button, and then click within the wideband scope spectrum display to place the narrowband channel where you want it.
Once placed, this new narrowband scope will be visible in the lower right portion of the TitanSDR application window. You’ll also hear audio for the narrowband selection.
The narrowband selection defaults in USB mode, but you can quickly change modes by selecting one from the panel above the narrowband spectrum. Your choices:
Tuning
After using the TitanSDR for only a couple of days, I found I was quite comfortable tuning through the bands. Every SDR application has its own quirks; the TitanSDR app gives you several tuning options.
Within a narrowband window, you may tune by:
Tuning within the wideband scope is as simple as clicking and dragging the narrowband shaded area.
Of course, wideband areas can be moved to different parts of the HF spectrum by simply clicking on the shaded wideband area within the panoramic scope and moving it to a different location. But you can only do this if there are no active narrowband channels within the selected wideband channel.
With the ability to load multiple wideband channels with multiple embedded narrowband channels, you might think tuning and manipulating the various channels would get confusing. But this is just not the case. Herein lies the excellent user design behind the TitanSDR.
The software engineers at Enablia obviously put time into designing their application for users who routinely use multiple channels. Each channel is clearly color-coded across the scopes, and selecting them is a simple process: one of four wideband channels via the panoramic display, and one of many narrowband channels via the wideband display. Indeed, TitanSDR produced a brief video (http://youtu.be/XDdilGykSuY) describing how to use the TitanSDR application interface. The concept of selecting and manipulating the various channels is so easy, I actually knew how to do it prior to receiving and installing the software…and all from this eleven-minute video tutorial.
Without a doubt, the TitanSDR user interface is one of my favorites among the numerous SDRs I’ve evaluated.
Speaking of multiple channels, if you have a particular combination of wideband and narrowband channels that you like to load each time, you can save the full configuration and reload it at startup, preserving every frequency and channel. Brilliant.
Recording
For shortwave archivists (like the author of this review!), the TitanSDR is very enticing. Even the most basic version of the TitanSDR allows for 4 wideband channels and 8 narrowband channels of simultaneous recording. This means that you can record a wideband channel and as many as eight individual live broadcasts consecutively. While rarely needed, it’s an impressive feature. Quite often I’ve wanted to record as many as three broadcasts simultaneously; my WinRadio Excalibur, for example, allows for as many as three consecutive broadcast recordings, but limited within a 2 MHz bandwidth. The TitanSDR has no such limitation. You could load four wideband channels across the spectrum––say, one within the mediumwave band, one on 41 meters, one on 31 meters, and one on 10 meters––and record or listen to up to eight individual broadcasts within those channels. The TitanSDR pro will even allow for up to 40 consecutive narrowband channels of recording.
The record and schedule functions are prominent in the narrowband scope window (above) and the wideband scope window.
What’s more, the TitanSDR has one of the most versatile automatic file naming systems I’ve ever used. Not only can it embed the date, frequency, and mode, but also the start time and end time. It also has a user-defined string which allows for more file name customization. And another nifty feature: the Titan can be set to embed either local or UTC time in the filename.
Yet another feature the archivist in me delights in? You can schedule narrowband and wideband recordings within the application––no need for an external program or macro.
Missing features?
As a product designed specifically for military and government applications, the Titan application currently lacks many of the features you might expect in a $1000+ software defined receiver. The version of the TitanSDR application (at time of publishing this review) lacks a variable notch filter, 90 second waterfall review, and an embedded time stamp––features one might well expect from a receiver in this price class.
Prior to publishing this review, I contacted Enablia with a list of features I thought should be included, and they agreed that these features should be added to appeal to the ham radio and shortwave listening customer base. Indeed, within a matter of two weeks, I was sent a new version of the Titan application with the addition of a number of keyboard shortcuts that I recommended. A few weeks later, I received another update which included the ability to set the maximum size of spectrum recording “chunks” to anything between 50MB and 2GB. Enablia plans to add more of the features for the radio hobbyist in time, but after this review has been posted.
If you’re seriously considering purchasing the TitanSDR, you might contact Enablia first to see if and/or when these features are to be added. I’m confident they will be added in time.
When I begin a radio review, I keep a checklist of pros and cons as I discover them to remind myself of my initial discoveries.
Here’s my list from the TitanSDR:
Pros:
Cons:
No doubt, I’m impressed with the TitanSDR, performance-wise. It’s as sensitive and selective as any SDR I’ve ever tested. Serious weak-signal DXers will be pleased with this rig.
Of course, there’s the daunting price tag of the TitanSDR, which makes it clear that this was a receiver designed for government and commercial use: the basic version of the TitanSDR retails for 1380 EUR, the TitanSDR Pro for an even heftier 1970 EUR.
This pricing places it well above the Microtelecom Perseus, WinRadio Excalibur and Elad FDM-S2, all of which can be purchased for $1000 or less.
Who might benefit from the extra cost of the TitanSDR? Those who need a receiver with a very robust front end. With no less than 16 pre-selectors, the TitanSDR is a great choice for those living in the vicinity of blowtorch radio stations. If you’re looking for a stable, easy-to-use flagship SDR with a rock-solid application to support it, you might just splurge on this impressive SDR.
I always ask myself at the end of a review if I would purchase the equipment I’ve spent a couple of months evaluating. I can honestly say that if I had the money, I would not hesitate to purchase the basic version of the TitanSDR. With its four wideband and eight narrowband channels, it would more than suit my receiver needs as a broadcast archivist.
1,380 EUR buys the basic version of the TitanSDR – With four WB (Wideband) channels, eight NB (Narrowband) channels (to be allocated on WB channels) and VAC (virtual audio) interfaces to third party SW decoders, this is a solid and adaptable SDR.
1,970 EUR buys the TitanSDR Pro – With four WB channels, 40 NB channels (to be allocated on WB channels), VAC interfaces to third party SW decoders, basic LAN control and plug-in software interfaces (by LAN Ethernet) to software decoders CODE300-32 by Hoka Electronic (http://www.hoka.net/products/code300-32.html) and Krypto500 by Comint Consulting (http://www.comintconsulting.com/k500.html), this SDR can sing and dance.

Many thanks to SWLing Post contributor, Richard Langley, who writes:
“Last January, I wanted to see if I could hear the BBC World Service’s technology program “Click” via shortwave.
I was and still am a regular listener to the podcast but I was home on a Tuesday afternoon stranded by a snow storm and tuned to one of the frequencies used by the World Service for west and central Africa, which usually come in reasonably well in eastern North America. To my disappointment, another program was aired at the time “Click” was going out on the real-time online streamed service. I kept listening but “Click” didn’t appear on shortwave later that afternoon either. In general, the programs going out shortwave were not the ones being streamed over the Internet.
I made enquiries to Bill Thompson, the knowledgeable co-host of “Click” and to others about when “Click” aired on shortwave but came up empty.
Fast forward to a couple of weeks ago. I got an e-mail from Bill asking me if I’d heard back from the BBC about the airing of “Click” on shortwave as he’d passed on my request for information. Unfortunately, I hadn’t, but his e-mail reminded me of my effort and so I did some more digging.
I once again scoured the BBC website and eventually found the World Service FAQ page. And, on that page, we find the answer to the question “Where can I find a schedule and frequency for BBC World Service programmes?”with the online program schedule as well as the program schedules for radio transmissions to the various world regions, including local AM and FM radio, DAB radio, satellite radio, and, for some regions, shortwave radio.
I noticed that, according to these schedules, “Click” is broadcast by radio at various times on Tuesdays and Wednesdays, depending on the target region, including some broadcasts by shortwave.
So, on Tuesday afternoon this week, I took one of my portable shortwave receivers (a Tecsun PL-880) to work and operated it from the back of my SUV in the parking lock of my building with a short wire antenna fed out through the rear window and recorded the audio.
Low and behold, I heard “Click” at 19:32 UTC on 15400 kHz from one of the transmitters on Ascension Island. Reception was not bad given the fact that the signal is beamed in the opposite direction to us and there’s a fair degree of radio-frequency interference (RFI) from various electrical and electronic devices in and around my building. The signal would have been much stronger in the African target zone. A short audio clip of the start of the program is [below] (lasts one minute).
I’m sure I could find a quieter location RFI-wise like one of the university’s playing fields and might try that next week.
After confirming that “Click” is indeed still on shortwave, I decided to make a chart of all the “Click” broadcast times including those via shortwave as the “Click” website only gives the times of the online streamed broadcasts. [Click here to download a] PDF-version of the chart. A “bullet” indicates a broadcast of “Click” by any transmission method for each target region. If, in addition to other types of radio broadcast, shortwave is used, then the frequencies (in kHz) and transmitter locations are listed. I think all the information is correct but I’m happy to receive corrections. The schedule should be good until October and I’ll try to produce an updated version after that.
It is good to see that the BBC technology program is still available via shortwave – a still-useful technology in many parts of the world. And, although I’ll still listen to “Click” via the podcast, it’s nice to know that I can still catch it on a Tuesday afternoon with a shortwave receiver.”

Many thanks, Richard! Like you, I’ve been a long-time fan of Click. Indeed, five years ago, I had the honor of being interviewed for the program [then known as Digital Planet].
I’ve heard Click a number of times via the BBC World Service on shortwave, but never noted the times and frequencies. Thank you so much for compiling this info for us, Richard, and happy listening!
Readers: Note that if Click’s shortwave schedule doesn’t work for you, you can always subscribe to Click’s podcast, or listen online.
Note: This post was updated December 3, 2015 with current broadcast schedule.
