Nothing to hear on shortwave? Jacques disagrees…

MauritiusIsland-IndianOcean-SM

Many thanks to SWLing Post reader, Jacques Catherine, who left the following comment on our post from 2012: Is there anything to listen to on shortwave?

“I live in Mauritius Island in the Indian Ocean and I’ve been listening to Shortwave since I was a kid (I’m 58 today) on my dad’s good old Phillips wooden valve radio.

I’m sorry, but shortwave is certainly not dead. After having read all the comments above, I come to the conclusion that reception definitely depends on your location.

The Tecsun PL-660.

The Tecsun PL-660.

I have two Tecsun receivers ( Tecsun S 2000 and PL 660) hooked to a Windom antenna and an ATU. I receive dozens of stations from all over the world here as well as a lot of stuff on ssb, including – in the morning – New York MWARA (8825.0 usb), Gander (8831.0 usb) or, in the evening, Brisbane (5634.0 usb).

Broadcast stations from Japan, Taiwan, India, Iran, Australia, Singapore, China, Africa and even the US, come in here loud and clear with very little static, depending on the season and time of the day. I think I’m privileged to be located where I am !

And I bought some years back a pair of cheap small wooden amplified speakers in Hong Kong that reproduce exactly the sound of my dad’s old valve radio!”

Thank you for your comment, Jacques. You’re right: it’s all about your location…and you certainly live in a prime spot!

I’m most fortunate that I live where I do–quite far away from sources of noise that plague our urban readers/listeners (and that have plagued me in the past). My location is not ideal (from a radio/receiving standpoint) because my ground conductivity is very poor and I’m in North America where very few broadcasts are targeted these days. I do, however, have the space for a rather large horizontal delta loop antenna that serves me well across the HF bands. I might have invested $50 in the antenna wire and components five years ago.

When propagation is good, some broadcast bands are actually packed tightly with signals. Indeed, Thursday last week, I could’ve easily logged two dozen stations on the 31 meter band alone.  Here’s a screen capture from the spectrum display of my SDR:

If you live in an urban area and feel that you’re missing out on the action, consider taking your receiver outdoors and away from interference. Take your receiver on hikes, camping trips or to the beach. You might be surprised by the number of stations you’ll log!

Recently, our friend London Shortwave has been posting an amazing array of broadcast recordings he’s made in a park in the middle of London, England. He’s the guru of mitigating urban interference.

When I have time to curate the recordings, I hope to do a 2016 update of “Is there anything to listen to on shortwave?“–it’s been on my to-do list for a while now.

Jacques, thanks again for your comment and reminding us to keep listening!

One year with the TitanSDR

TitanSDR-VOG

Last year, I reviewed the TitanSDR Pro by the Italian manufacturer, Enablia,. I was very impressed with not only this receiver’s performance, but also its accompanying application’s user interface. I also noted in the review that the TitanSDR is pricier than many other benchmark SDRs on the market ($1380-1970 EUR) but it is, after all, essentially a military-grade SDR that has been ported to the enthusiast/ham radio market.

I’ve been using and testing updates to theTitanSDR Pro for a year now, and I continue to be just as impressed with this receiver––and, especially, with the company who manufactures it, Enablia.

TitanSDRPro-3

I wondered at the time of my initial review how supportive Enablia might turn out to be; I knew time would tell.  Since my original review last year, Enablia has been regularly updating the TitanSDR application, adding many features requested by its users.  This shows a remarkable degree of responsiveness, and I now feel safe to say that that Enablia is an exceptional manufacturer with an exceptional product.

Only recently, I received an update which added two notch filters per narrowband channel, memories that retain AGC and notch filters settings, and sessions that retain AGC settings. I understand Enablia is also preparing updates that improve upon memory management, user interface, audio defaults, as well as offering a few tweaks to the existing feature set.

Overall, Enablia developers are certainly making this signal intelligence SDR cater to the ham radio and enthusiast market even better than before.

Though I use a number of SDRs, I reach for the TitanSDR any time there are multiple-band openings since it can record spectrum and audio across the entire LW/MW/SW landscape. Unlike my other SDRs, it’s not limited to an (already generous)  2-6 MHz recording/listening window.

For example, on Thursday night I had a lot on my listening/recording plate as there were a number of band openings. I had the TitanSDR tuned to:

  • the 31 meter band,
  • the 20 meter ham radio band,
  • the 49 meter band (specifically monitoring South American stations), and even
  • the mediumwave band.

The TitanSDR was recording spectrum on the 49 meter band while I made this AF recording of the Voice of Greece on the 31 meter band (9420 kHz, starting around 00:26 UTC on April 8, 2016):

Audio Player

Surprisingly, all of this recording wasn’t taxing my PC, nor the TitanSDR.

The TitanSDR application is highly stable and uses resources efficiently. Indeed, in the past year, to my knowledge the TitanSDR application hasn’t crashed even once, despite my rigorous demands of it. Since it runs nearly 24/7 in my shack, on a four-year old PC (third generation i5 Win 7), that’s saying a lot.

SWLing Post reader, Tony Roper, is also a heavy TitanSDR user and recently posted this 30+ minute video demonstrating some of the TitanSDR’s new features. Note that his screen capture software produced fairly low audio, so you’ll need to turn up the volume to hear his commentary:

In short, I stand by my conclusions drawn last year in my TitanSDR review:  although pricey compared to the competition, for those who can afford the price tag, the TitanSDR is a worthy hard-core DX machine that is especially useful to need a receiver with a bullet-proof front end, to weak-signal DXers, and to radio archivists like yours truly.

ISS Slow Scan TV reception opportunities in April

ISS Slow Scan TV in April

ARISS reports that International Space Station (ISS) Slow Scan Television (SSTV) transmissions on 145.800 MHz FM may take place between April 11-15, 2016

The schedule for the ARISS commemorative event is currently:
• Setup and activation on April 11 about 18:25 UT.
• Paused April 12 from 12:15 until 14:15 UT to allow for a school contact with Romania.
• Paused April 13 from 12:45 until 14:30 UT to allow for a school contact with Argentina.
• Deactivation on April 14 at 11:35 UT.

This opportunity should cover most of the world during the operational period. The image transmissions should be on 145.800 MHz and the mode is planned to be PD180.

In addition, MAI-75 (SSTV Experiment) will be conducting two sessions afterwards. The first one is April 14 from 14:45 until 18:00 UT.
The second session is on April 15 from 14:10 until 19:00 UT. These times do not cross N. America but will provide opportunities for Europe, Southeast Asia, Australia and S. America.

Can you help Paul ID this station?

SX-99-Dial-Nar

Many thanks to SWLing Post contributor, Paul Walker, who is seeking your help. Paul writes:

Well, I think I have an ID but I also think I’m wrong.

I had weather in english by a female computerized voice on 6518.80USB. Heard on 04/10/16 at 910PM AKDT (0510UTC 04/11/16) in Galena, Alaska using a Tecsun PL880 and 80 foot longwire.

Here’s the audio, all 7 minutes and 3 seconds worth:

https://www.youtube.com/watch?v=_GanBsfuyS0

Click here to listen on YouTube.

It was fairly clear and pretty steady here in the middle of central Alaska.
It was giving weather for the Caribbean and apparently the only hit I can find online for either both from Eibi and Google says that 6518.80 USB belongs to Punta Carretas, Uruguay.

If that’s really what I heard, A.) It was strong and B.) Why was it in english?
I suspect I didn’t really have them and it was from somewhere else. This signal is just to be good to be Uruguay, but a DX says they are the only things that come up in a search for 6518.80 USB but the times I heard them don’t match.

If you can help Paul, please comment!

eBay find: Rack of classic receivers

Rack-Gear

Many thanks to SWLing Post contributor, Dan Robinson, who shared a link to this rack of classic cold war era receivers. The starting bid is $943.75 and there is no shipping cost as it’s local pickup only (no surprise there).

Here’s the description from eBay:

LOCAL PICK UP ONLY Paso Robles Ca. 93446. Good condition, rack of Communications and Amateur Radio receivers. Includes Hallicrafters R-46B loudspeaker, two each Hammarlund SP-600 JX-26 receivers with one frequency readout as shown above the top receiver, a National NC-300 receiver with calibrator accessory, and a Hallcrafters SX-101A receiver with calibrator accessory. The rack cabinet is included. All have normal wear for vintage electronics, worn with faded, chipped and rust spots. The SP-600 receivers (both) dial slips and may need repair. All units may need further repair, alignment, or refurbishing. Local pick up only, I can help loading into your vehicle. 70hi 22wide 20deep weights about 600 pounds

Click here to view on eBay.

I think this would be a great deal if all of the equipment was in working order. I suspect this seller hasn’t tested anything and is, most likely, not a radio enthusiast. I bet the reason the SP-600 dials are spinning freely is because the tuning lock is engaged on each unit–possibly a good sign that the previous owner took care of the equipment.  All of it looks good (cosmetically) for its age.

If I were interested, I’d go by and check this out in person prior to bidding.

RCI programming returns to shortwave via Shortwaveservice.com

SX-99-Dial-Nar

Many thanks to SWLing Post contributor, Richard Langley, who writes:

Radio700Here is the response from Christian Milling, the director of Radio 700 and Shortwaveservice. Note that he is stressing the difference between Radio 700 (as a program and separate broadcasting station) and Shortwaveservice (as the provider of technical services for the shortwave transmitters at the Kall-Krekkel). The transmitters are actually maintained by Burkhard Baumgartner, DF5XV, under the name “Classic Broadcast”.

All three operations are closely linked so it’s understandable that there is confusion about who does what. Furthermore, in the WRTH, we have “Radio 700 Kurzwellendienst” (Radio 700 Shortwave Service). No reply directly from RCI yet.

Dear Richard Langley,

thank you very much for your e-Mail. Indeed we (not Radio700 but Shortwaveservice.com as technical provider) has set up an official cooperation with Radio Canada International which allows us to transmit the english, french and spanish programming. So this will be a long-term relay on a legal basis. As we prepare a spanish language outlet, the spanish broadcast of RCI will follow later on on SW.

The propagation conditions are a bit lousy at the moment, resulting in a bigger skipzone since a few days on 7310 kHz. Normally we boom into on that frequency also in Twente (which is approx. 200km away from our tranmitter [sic] site). We got some reception reports from the UK, which one from Manchester I’d like to quote: “Good clear signal, just some slight fading from solar disturbance that was taking place. How wonderful to hear Radio Canada International back on shortwave again, I really hope they continue broadcasting from Kall, I couldn’t believe it when I saw they would be broadcasting here this week.”

As the brodcasts [sic] are intended for the reception in europe and most speak either french or english and our weekend-schedule is very crowded, we only managed to find a slot for both languages at a time. But we will think about a re-run of the shows on a different day.

Thanks for tuning in!

If you have any further questions, don’t hesitate to contact me.

Best regards,
Christian Milling

Thanks so much for the update, Richard!

Update: German communications regulator to allow AM digital modes

FLdigi-VOARadiogram

As a follow-up to a previous post, many thanks to several SWLing Post readers who noted this news on the VOA Radiogram website:

The German communications regulator Bundesnetzagentur has changed its mind about allowing digital modes on shortwave broadcast transmitters in Germany. Apparently BNetzA thought that Channel 292 was transmitting the text and images in single sideband (SSB), which is how amateurs, military, etc, transmit the digital modes. Now that they know that the MFSK32 and other modes are sent as program audio on an analogue amplitude-modulation shortwave transmitter, their objections were withdrawn.  (It’s similar to A2A modulated CW.)

BNetzA prefers that the term MFSK32 not be used to describe these broadcasts, but we have to specify the mode so that you can set Fldigi or other decoding software to the correct mode. In any case, the weekly MFSK32 transmission will resume on The Mighty KBC, and DigiDX will return to Channel 292.

Meanwhile, VOA Radiogram this weekend will be all MFSK32 except for the transmission schedule in Olivia 64-2000 under the closing music.
