The Elad FDM-S2 SDR: Unboxing, installing, and a first recording

FDM-S2-Front

At the Dayton Hamvention last month, I made a point to check out the Italian radio manufacturer, Elad. Though I’ve known about Elad for some time, I hadn’t investigated their offerings yet simply because I was under the impression they only sold and warrantied their equipment within Europe. Fortunately, Elad has begun supporting and shipping their products within the US, via their division Elad-USA.

Elad-RadiosElad’s booth was one of the first stops I made at the Hamvention; I met with their representatives there, who answered my many questions. While Elad is soon to release their flagship tabletop SDR transceiver (the FDM-DUO, see below), I was more interested in their flagship receiver, the FDM-S2–which really impressed me during their demo.

The FDM-DUO attracted a lot of attention at the Elad booth.

The FDM-DUO attracted many visitors at the Elad booth.

Yesterday, I unpacked a loaner FDM-S2 Elad sent for review; this review will be published first in The Spectrum Monitor magazine, and following, here on the SWLing Post.  While it will take some time to piece together a full review for TSM, I thought I would periodically post recordings (and note FDM-S2 features) I discover along the way…

Unboxing the FDM-S2

FDM-S2-Box

Being a receiver with a small footprint (a major plus, in my world), the FDM-S2 comes in a small box (measuring only 6.5 x 5.5 x 2 inches).

Contents of the box are few and simple: the FDM-S2 receiver, a black cloth carrying bag, and a 4GB USB drive with installation software and documentation. A standard USB cable was also included in the shipping box.

The FDM-S2 metal enclosure is beautifully engineered, and feels of excellent quality in my hands.

Installation

I found installation of the Elad FDM-S2 to be fairly straightforward. However, I would encourage you to follow the included guide, since installation is a two-step process:

  1. First, you install a C++ package on your Windows PC which, when complete, triggers the actual Elad software installation: this is a two-part installation that you only initiate once.
  2. Secondly, you install the USB driver for the FDM-S2, found in the installation folder of the supplied software. At time of posting, the USB driver cannot be automatically discovered and installed by your PC; you must initiate the installation via the device manager. However, this is very easy: the guide takes you through the process step-by-step.
On the back of the FDM-S2 you'll find an HF and VHF SMA antenna ports, a USB port, serial interface, and on/off switch.

On the back of the FDM-S2 you’ll find HF and VHF (SMA) antenna ports, a USB port, serial interface, and on/off switch.

The FDM-S2 derives its power from the same USB cable that is used for data, no separate external power supply required–a huge plus, for those of us who like to travel.

Once I installed the software and driver, I hooked up my antenna to the HF SMA connector on the back, turned on the FDM-S2, and launched the application. The FDM-S2 clicked to life, and the application ran on the first go: very nice!

I spent a good hour or so familiarizing myself with the Elad software yesterday evening. It’s quite a departure from the WinRadio Excalibur and Microtelecom Perseus applications with which I’m most familiar. Nonetheless, while I’m still learning how to adjust the spectrum bandwidth (which can be a full 6 MHz wide!) plus manage the four virtual receivers, I found I was able to do quite a bit of band-scanning.

In fact, I noticed some great music on 9,420 kHz, the former Voice of Greece frequency:

FDM-S2-Waterfall

I initiated my very first AF recording on the FDM-S2 (see screen capture above). The process was quite simple and I’m very happy with the level of customization Elad affords in its software; indeed, I can set the file name to automatically note the frequency, time, date and mode.

Day One with the FDM-S2? So far, so good. The Elad application is very customizable, hence has a higher learning curve than SDR applications I’ve used in the past. Thus I’ll need to log quite a few hours on the FDM-S2 before I can say that I’m proficient.

Readers: Have you had experience with the FDM-S2?  Any hints or suggestions?  Please comment–!

Pirate Radio Recordings: Tip & Elvis Show

Led Zepplin is one of the many artists you'll hear on this pirate broadcast.

Led Zepplin is one of the many artists you’ll hear on this pirate broadcast.

For your listening pleasure: over two hours of the Tip and Elvis Show. This Euro pirate  broadcast was recorded by Shortwave Radio Audio Archive contributor, Frank.

Tip and Elvis was broadcasting on 6,220 kHz in AM–you’ll hear some adjacent digital interference, but signal strength is pretty good for (most likely low power) pirate radio. This recording starts around 20:30 GMT on May 31, 2014.

Remembering Radio Beijing: 25th anniversary of the Tiananmen Square massacre

Today is the 25th anniversary of the horrible events that took place in Beijing’s Tiananmen Square on June 4, 1989, during which Chinese troops opened fire on unarmed student demonstrators.

In this off-air shortwave radio recording of Radio Beijing, made on June 3rd, 1989, you’ll hear the news reader/editor depart from the script and comment on the massacre of protestors in Tiananmen Square:

It’s believed this brave news editor was detained shortly after the broadcast and spent years in a detention (re-training) camp.

Rest assured, you will hear no mention of the Tiananmen Square protests on China Radio International today–even though this year marks the 25th anniversary of the event. China’s state media goes to great lengths to keep this sort of on-air protest from happening again. State media even tries to limit on-line research of the protests; last year, we posted a fascinating article which listed banned search engine terms in China.

I also encourage you to check out Jonathan Marks’ comments (from a broadcaster’s perspective) on this particular Radio Beijing broadcast.

Pirate Radio Recordings: Wolverine Radio

SWLing Post reader, Steve Yoth, decoded this Wolverine QSL two weeks ago using a Flex 3000.

A previous eQSL from Wolverine Radio. Try decoding the one at the end of this recording! 

For your listening pleasure: 1 hour, 20 minutes of the pirate radio station, Wolverine Radio–recorded May 26, 2014 starting around 1:20 UTC.

Wolverine was broadcasting on 6,950 kHz in the upper side band. Typical of Wolverine, lots of music variety which spans the decades and no commentary other than station ID throughout.

At the end of this recording, you’ll hear an SSTV QSL card being transmitted.

Try decoding the QSL image from this recording–it’s quite easy! I usually decode Wolverine’s SSTV QSL with Chris Smolinski’s SSTV app for iPhone, but there are other programs to do this. The eQSL above came from a broadcast about two weeks ago and was submitted by SWLing Post reader, Steve Yoth.

Pirate Radio Recordings: Hot Legs Radio (corrected)

"Grandma! Is that Cyndi Lauper buried in the static?"

“Grandma! Is that Cyndi Lauper buried in the static?”

For your listening pleasure: about 20 minutes of pirate radio station, Hot Legs Radio–recorded May 25, 2014 starting around 1:55 UTC.

Hot Legs Radio was broadcasting around 6,925 kHz in AM.

Hot Legs was rather weak and somewhat over-modulated during this broadcast. Indeed, in regular AM mode, I couldn’t make out the station ID at all. Fortunately, by turning on the WinRadio Excalibur‘s AM synchronous detector and selecting the less noisy lower sideband, I dug the signal out of the noise. AM sync also helped compensate for the over-modulation.

You’ll hear me re-tune a couple of times in this recording. Hot Legs’ signal was a bit of a moving target.  I don’t think it would have been as noticeable in standard AM mode (which is more forgiving of drift), but in AM sync, you’ll hear a tone when the frequency shifts.

Still, I’m quite happy to have caught Hot Legs Radio–a new pirate logging! Hope to hear them on again soon.

Update: Correction to station name. I originally posted this as “Hot Raves Radio.” Many thanks to Andy Yoder for the correction!

I’m very grateful to Shortwave Radio Audio Archive contributor, Greg Shoom, who is digitizing shortwave radio recordings he made in the 1970’s.

His latest contribution is a 1976 recording of HCJB’s 45th Anniversary broadcast. This is a special program, broadcast on Christmas Day of 1976 to commemorate the 45th anniversary of the founding of HCJB. Greg made this recording from his home in Kingston, Ontario, Canada on December 25, 1976, starting at 02:30 UTC on 6,095 kHz.
