Radio World: The evolution of shortwave radio

4 Replies

Many thanks to SWLing Post contributor, Richard Langley, who shares the following article by James Careless in Radio World Magazine.

The article includes interviews with Andy Sennitt, Kim Andrew Elliott, Nigel Fry, and even yours truly. The following is a short excerpt taken from the introduction of the article:

(Source: Radio World)

OTTAWA, Ontario — With the advent of radio in the 20th century, the shortwave band (1710–30,000 kHz) soon became a hotbed of long-distance radio broadcasting. Used primarily by state-run international broadcasters, plus ham radio operators and ship-to-shore radio communications, the shortwave band was prized due to its astoundingly broad reach.

That reach was — and is still — made possible by the tendency of ground-based shortwave radio transmissions to bounce off the ionosphere and back to earth; allowing shortwave broadcasts to “hop” repeatedly, increasing a broadcast’s range while minimizing its decay.

[…]At the height of the Cold War, the shortwave bands were packed with content as the Voice of America and West Germany’s Deutsche Welle (Voice of Germany) traded ideological punches with Radio Moscow and East Germany’s Radio Berlin International. This is because analog shortwave radio broadcasting was the only way for both sides to make their political cases cross international borders: There was no satellite TV, let alone any internet.

Read the full, in-depth article on the Radio World website…

This article is well worth reading and one of the more in-depth pieces I’ve seen in a trade publication or news site recently.

I should add that I completely agree with James Careless’ conclusion:

“[T]he research that went into this article suggests that the shortwave band is sufficiently alive to be still evolving.”

The fact is, the shortwave landscape is not what used to be in the Cold War. Many of those big voices have left the scene and, in the process, left the door open to others.

The shortwaves are a dynamic communications space that continues to evolve.

That’s why I keep listening.

Radio-Sky Spectrograph: Radio Astonomy with the SDRplay RSP

The SDRplay RSP software defined radio

(Source: Amateur Radio Astronomy blog)

Thanks to the efforts of Nathan Towne, we now have the ability to use [the SDRplay RSP] with Radio-Sky Spectrograph (RSS).

[…]As with RTL Bridge, a intermediary program sits between RSS and the receiver. This program was written by Nathan Towne and is named SDRPlay2RSS, not too surprisingly. This is a dot NET program and if you are up to date on your dot NET run-time updates you should be fine. Installation is a no brainer as SDRPlay2RSS comes with the RSS 2.8.18 update. SDRPlay2RSS does not come with the current full install of RSS so you must do the Full install and then the Update.

Breaking: 2017 Dayton Hamvention to be held at the Greene County Fairgrounds

Many thanks to SWLing Post contributor, Scott Gamble (W5BSG), who writes:

I just saw this local news post about the venue for Hamvention 2017.

XENIA, Ohio (WDTN) – Days after Hara Arena announced it will close its doors, an announcement from Greene County officials revealed that Hamvention will be held at the Greene County Fairgrounds next year, according to our partners at the Xenia Gazette.

The event for ham-radio enthusiasts generated about $21 million last year and drew a crowd of more than 27,000 for Montgomery County. The proceeds for this year’s event will now go to Greene County.

And here is a link to the fairgrounds site for information about the location.

Many thanks for the tip, Scott!

I just did a quick distance calculation on Google Maps and determined that the distance between HARA Arena and the new location is only about 35 minutes.

For some of us who regularly stay on the east side of Dayton, our commute may be even be a little shorter.

At first glance–and since I’ve never been to this facility, I can’t speak with any certainty–it looks like there’s very little in terms of indoor exhibitor area. I’ve pasted a screen grab from the Fairgrounds website showing a list of their buildings and dimensions:

I had done a little research the other day and came to the conclusion that Montgomery County and the City of Dayton had no truly suitable locations for the Hamvention.

Looking at the official Dayton Convention and Visitors Bureau website, there’s simply nothing large enough to accommodate the Hamvention exhibitors and visitors . The biggest offering is the Dayton Convention Center, but it’s tiny compared to HARA Arena.

There’s also the Nutter Center, but it’s not designed as a convention space, so to speak.

Moving to Cincinnati, there is the Duke Energy Convention Center, which looks to be as modern as the facility in Friedrichshafen, Germany. It might hold the indoor part of the Hamvention, but doesn’t look big enough to handle the parking and a flea market.

I’m sure DARA has done their research and the Greene County Fairgrounds are the next best option. I hope vendors and exhibitors agree and attend next year.

I plan to attend the 2017 Hamvention and I’m hoping the new facility will please everyone. I imagine it’ll be no small task for DARA to relocate such a large event.

Selecting a budget antenna for urban radio listening

12 Replies

Yesterday, an SWLing Post reader contacted me with questions regarding budget antenna choices for an urban apartment. He’s about to purchase an SDR, but knows that a decent antenna capable of coping with urban radio interference is a critical component.

I suggested that, since I’m no expert with urban interference, he pose his question to the SWLing Post community. Here’s his reply and request:

I know I’m a little behind some of my other radio friends, but I’m finally moving up to a software defined radio. Specifically the affordability of the SDRplay RSP and all good reviews for it have encouraged me to make the leap.

The SDRplay RSP software defined radio

I suppose it should go without saying that once I purchase an SDRplay I would like to use it, which might not be so easy. I live in a big city full of RF pollution, and most of my listening will be in a room where there’s a fair amount of electronic gadgetry.

So, without spending a lot of money, I’m curious if any of your readers might have suggestions about what I might purchase as a “starter kit” for a new SDR user in such a scenario. I also plan to take the SDRplay with me when I have forays out of the city, but I envision that some sort of long wire might be sufficient for listening out in the countryside.

I live on the second floor in an urban apartment, and have two windows in the room where I’ll be listening. There is zero chance that I can hang or attach anything on the outside of the house here. So, my most pressing question is about antenna ideas. I’ll need something inexpensive, as I mentioned, and something “off the shelf.” I don’t have the skills or tools to really “build” anything, unfortunately. So is there some less than pricy antenna or antennas I should look at? Or is there some hope of doing something with a long wire indoors?

Tecsun AN-100 portable loop antenna

And will my little Tecsun AN-100 AM loop antenna going to help me at all? I mostly plan to listen to MW and the HF bands, but I will inevitably check out signals far up the bands as well. So advise about listening to these bands is also of interest to me.

Other than that, I understand it’s important to attach the SDR to the laptop with a USB cable with ferrite chokes. And it probably wouldn’t hurt to buy some extra ferrite chokes to attach to other cables I might be using. I also plan to buy a NooElec mini-balun for use with a long wire antenna, and I already purchased a PowerMate USB knob because I still prefer to do my “tuning” that way.

So other than those basics my questions would be regarding connecting cables and adapters, and the best lengths of cable to use. Should I have some cable between the balun and SDR? I believe I’ve read that it’s better to have a longer USB cable and a shorter coax to the antenna, correct? And when it comes to using a wire antenna, are there preferences as far as what type or gauge of wire to use?

I am also interested in any general suggestions or tips from SDR users on getting started. In general, I’m pretty good with navigating through software, it’s usually the hardware issues that stump me. I’m looking to spend between $100 to $150 tops on everything besides the SDR, and I’d like to hear about peripherals, cables, adapters and connectors which when added all together won’t bust my bank.

I’m sure there’s plenty of people who read this wonderful blog who have plenty of useful knowledge regarding SDR listening on a budget. And I hope a few could share a little of their experience and collected wisdom on this topic here, for me and for others considering turning their computers into receivers…

Indeed. I appreciate this reader’s question, since many listeners live in environments with heavy radio interference. While we’ve published a number of posts touting the virtues of magnetic loop antennas, I don’t think we’ve ever looked for solutions at or below $150 US. While this may be a challenge, I’m also certain there are a number of readers who’ve found solutions to this problem.

So, Post readers, what might you do–or have you done–in similar circs? Please feel free to comment, and let’s explore inventive and affordable solutions for this reader!

Turn your Elad FDM DUO into a portable receiver, with a 200 metre longwire

5 Replies

As some of the subscribers to Oxford Shortwave Log will know, I’ve been talking about building a battery pack for my Elad FDM DUO to take it out on a DXpedition. Finally, I found the time to quickly do just that with some parts that cost less than £10 – as the video below demonstrates in more detail. The FDM DUO input voltage is stated as 13.8V and although 12V would probably have been sufficient, a couple of very cheap battery cases later, 9 x 1.5V ‘C’ cells and about 20 minutes of somewhat unpractised soldering did the trick. I have also put together a 200 metre longwire antenna, deployable from a large spool, with a termination connector to add resistor grounding for a Beverage Antenna configuration, should I wish to do so in the future. I used two spools of 100 metre equipment cable, soldered together and protected with heat-shrink.

Regular viewers of my youtube channel will know that I spend much of my shortwave listening time out in an Oxfordshire wood where QRM is negligable and Tropical Band stations can be heard with, at times, unprecidented signal-to-noise. This is the first time I’ve used a longwire greater than 100 metres in length, however, to be resonant at two wavelengths for 90 metres and 3 wavelengths for 60 metres was the objective. I hope the already fine Tropical Band listening to be had out in the Oxfordshire countryside will improve further.
