Review: DoxyTronics Portable HF Magnetic Loop 8020CA

-by Troy Riedel

Before I purchased the DoxyTronics 8020CA antenna, I emailed the owner/manufacturer and asked if he felt this antenna would be a good choice with the radios that I own. He promptly and courteously answered my question and I purchased the antenna on September 30th. I received the antenna approximately 6-days after I ordered it.

The DoxyTronics 8020CA magnetic loop antenna

I have been evaluating the antenna for 5-6 weeks mostly on my Grundig Satellit 750 and my Grundig G3. I have used other portables but the two aforementioned Grundigs were the radios I used most.

The antenna control box has a ¼-20 hole on the bottom so it can be mounted to a video camera tripod. The assembled antenna weighs 3 lbs. I tried using a light duty DSLR tripod that I own, however that was nowhere near sturdy enough. I had to use a heavier duty tripod (Ravelli AVT) that I use for astronomical purposes. This Ravelli has a weight capacity of 16 lbs and it easily supported the antenna. I’m confident a much smaller and lighter duty tripod than the Ravelli could be used, I simply don’t own anything in-between as my astronomical binoculars and binocular telescopes weigh 5 – 14 lbs.

The 8020CA Antenna consists of a large tuning knob and control box. The control box has switch settings of 3-5 Mhz and 5-15 Mhz. In testing, I found that I could “tune” up to 17.840 MHz. No batteries are needed to operate.

The antenna worked equally well with all of the “portable” radios that I tested (I am a SWL’er, not a ham).

I can summarize the antenna’s performance as this: it is not a magic elixir that will allow you to capture signals too faint to recognize without the antenna attached, but it definitely enhances the signal and “stabilizes” it to the point where the level of the signal remains relatively constant (less peaks & troughs in signal strength).

Hopefully you can hear what I have summarized and concluded. I have included a two and one-half minute recording of the following:

Radio: Grundig Satellit 750
Recorder: RadioShack 140-214
Freq: 7.310 MHz
BW: Wide
Broadcaster: Radio Romania International
Date of Recording: 15NOV2016
Time: 2309 – 2313 UTC

00:00 – 00:30: 8020CA Antenna Attached
00:30 – 01:00: Radio’s Whip Antenna
01:00 – 01:30: 8020CA Antenna Attached
01:30 – 02:00: Radio’s Whip Antenna
02:00 – 02:30: This last 30-second segment is with the 8020CA attached, however I am panning the Ravelli tripod 360-degrees in the horizontal. You will hopefully notice that there is a “sweet spot” where the signal and reception is the best of the entire 2:30 recording. I had set-up the antenna and I completed a quick, test recording of Radio Romania. But conditions changed slightly and the best signal during the recoding was approximately 50-60-degrees away from where the best reception was earlier. This is a positive for the antenna: you can pan the tripod head where the antenna sits to null and/or find the best signal.

Note: this is my first shortwave and radio-related review I have ever done. I have done many astronomical reviews – where I have much more experience – so please be kind towards this first attempt.

No worries, Troy! We’re kind and appreciative here–especially since guest posts are all about sharing our experiences and experimentation!

I must say, the DoxyTronics loop is doing a fine job mitigating the local QRM/interference that is easily heard when only the telescopic whip is being used. I’m also impressed that a passive loop this modest in size has so much gain without amplification.

Thanks, again, Troy for sharing your review!

BBC World Service to launch 11 new language services

5 Replies

(Source: BBC News)

The BBC World Service will launch 11 new language services as part of its biggest expansion “since the 1940s”, the corporation has announced.

The expansion is a result of the funding boost announced by the UK government last year.

The new languages will be Afaan Oromo, Amharic, Gujarati, Igbo, Korean, Marathi, Pidgin, Punjabi, Telugu, Tigrinya, and Yoruba.

The first new services are expected to launch in 2017.

[…]The plans include the expansion of digital services to offer more mobile and video content and a greater social media presence.

On Wednesday the BBC launches a full digital service in Thai, following the success of a Facebook-only “pop-up” service launched in 2014.

Other expansion plans include:

extended news bulletins in Russian, with regionalised versions for surrounding countries

enhanced television services across Africa, including more then 30 new TV programmes for partner broadcasters across sub-Saharan Africa

new regional programming from BBC Arabic

short-wave and medium-wave radio programmes aimed at audiences in the Korean peninsula, plus online and social media content

investment in World Service English, with new programmes, more original journalism, and a broader agenda

The new language services mean the BBC World Service will be available in 40 languages, including English.

Lord Hall has set a target for the BBC to reach 500 million people worldwide by its centenary in 2022.

In addition, Mike Terry, posted a link to this Leading Article from The Times which focuses on the BBC expansion. This content is behind a paywall (though you can register to read two free items per week) but here is an excerpt from the conclusion that I found particularly interesting:

“The radio may seem an irrelevance in the age of the internet but it is the most intimate of the so-called mainstream media and as such poses a challenge to authoritarian rule. Radios are cheap, ubiquitous and can whisper truths under the bedcovers. There is nothing that dictators hate more than direct access to the ears of their subjects.”

Indeed.

What radio would you grab in a fire?

32 Replies

Lately, fires have been on my mind. No doubt, this is because there are so many wildfires in the greater southern Appalachian region right now, which is in the midst of a record drought. Brush fires start up almost daily, and no rain is in sight. In the mountains, the air is hazy with smoke, and it’s become a struggle for fire departments to contain these blazes, even with help from outside the region.

Living, as we do, in a forest, we’ve always had to think through contingency plans if a forest fire should threaten our home: with only a two hour (or so) warning, what items would we grab and load into our truck?

Of course, we’d likely focus on those things that are irreplaceable and thus essentially invaluable: our few family heirlooms, boxes of photos, documents––you know, stuff you can’t buy.

But what about radios? I hope I’ll never be forced to choose the one thing I should save from my shack, because there are several to which I’m rather sentimentally attached…There’s my Zenith Transoceanic, for example–the first proper shortwave radio I ever owned. There are also a number of vintage radios as well as some SDRs which have become my staple receivers.

In the end, though, there’s no question which radio I’d grab. It would have to be my Scott Marine Radio Model SLR-M, affectionately nicknamed “Scottie.”. True, she’s not even close to portable at a solid 90 pounds, but I’d strap her to the roof of my vehicle, if I had to.

Why? Well, it’s the most pristine vintage radio I own, and I use it daily. If it’s not tuned to Radio Australia in the morning, it’s tuned to my AMT3000 AM transmitter on 1570 kHz drawing in any of a number of stations I relay from my WiFi radio.

Scottie simply isn’t replaceable. Even though my Elecraft KX3 probably costs more in terms of monetary value, I could eventually scrape together the money to buy another KX3. But I couldn’t buy Scottie again. Not this one.

So, there you go: after we’ve saved those things important to our family, I’d grab a 1945 receiver and haul it to safety.

Post readers: Now I’m curious–if your home was threatened by fire or other disaster, what radio would you save? Please comment!

Radio World explores the PantronX Titus II

6 Replies

Many thanks to SWLing Post contributor, Tom Ally, for sharing the following article by James Careless in Radio World:

Well, if you are the engineering firm PantronX, you have the Titus II software-defined radio. And when you plan to sell this ultimate receiver for less than $100 each, you hope you have a consumer sensation for the worldwide broadcast market.

Unveiled by the Panama-based company at an international broadcasting meeting in Miami in August, the Titus II SDR is not yet shipping. But it is described as capable of receiving and playing analog and digital radio transmission formats including AM, FM, shortwave, HD Radio, DAB+ and Digital Radio Mondiale. The company is considering adding a DRM+ decoder.

The initial market is among worldwide broadcasters, particularly those serving countries where listeners may lack internet; a secondary market is individual listeners, hobbyists and others. PantronX will not supply all decoders for all formats but add them preloaded as needed.

Advocacy group calls for reopening of Eye Radio

1 Reply

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following item from the Sudan Tribute:

November 12, 2016 (JUBA)- The African Centre for Transitional Justice (ACTJ) has called on South Sudanese authorities to reconsider their decision to reopen the unilaterally closed independent radio station, asserting it is a clear violation of press freedom.

“This is a blatant press freedom violation. We call on authorities in South Sudan to reopen the radio station. In this particular context South Sudan needs free and fair media able to play a positive role in the country’s reconstruction and reconciliation”, the group says in a statement.

The statement condemned what it described as “disruptive and inexplicable act”, saying it is nothing short of an attempt to suppress media freedom in the region and demand that Eye Radio be allowed to resume broadcasting immediately.
