I don’t have a “shack”, but I wanted to take the time to share with you my “listening post”. But first, let me start from the beginning.  

I’d call myself an amateur astronomer first – and a Shortwave Listener (SWL’er) second (I have never been a Ham Operator).  

I started my astronomy hobby as a young kid who was enthralled by the Apollo Missions.  I was also fascinated by weather & I learned how to make short-term 12-36 hour forecasts by making cloud observations, following the barometric pressure trend & noting changes in wind direction.  I am still an amateur astronomer (a very expensive endeavor).  I was able to pursue my childhood interest in weather and I became an Aviation Weather Forecaster in the military (I also instructed synoptic meteorology in the military at the schoolhouse).  I promoted myself out of meteorological jobs in my Service but I was able to transition to a deployable job that allowed me to visit 50 countries.  I retired with slightly over 30-years served.

When I was a kid, a buddy had a shortwave radio but we could never hear anything (we had no clue).  I had an Electro-Brand EB2100 5-band radio that had AM/FM, Police, Fire, Aviation & NOAA (if I recall).  We heard transmissions on that EB2100!  I didn’t truly discover shortwave until the early 1990s.  My first shortwave radio was a Panda 2006 (I challenge readers to look-up that model in the 1994 Passport to World Band Radio).  I liked shortwave so much, I sold the Panda to help finance my next radio.  I pre-ordered & subsequently received one of the first Gru?ndig Yacht Boy 400s released in the U.S. (I still have the radio & the receipt).

I think, for a SWL’er, I have a decent collection of shortwave radios & antennae:

  • Grundig Yacht Boy 400
  • Grundig  G6 Aviator Buzz Aldrin Ed.
  • Grundig G3 Globe Traveler
  • Tecsun PL-390
  • Sony ICF-7600GR
  • Tecsun PL-365
  • Grundig Satellit 750
  • Grundig G2000A Porsche
  • RadioShack 140-214 Digital Recorder
  • AMECO TPA Active Antenna
  • Crane Twin-Coil Ferrite Antenna
  • DoxyTronics 8020A Passive Antenna
  • Kaito KA35 Active Loop Proximate Antenna
  • NASA PA30 Wideband Passive Antenna
  • A Helical/Slinky Antenna
  • RadioShack 20-280 Active Antenna
  • Sony AN-LP1 Active Magnetic Loop Antenna
  • Tecsun AN-200 AM Passive Antenna
  • Terk Advantage AM-1000 Passive Antenna
  • TG34 Active Magnetic LoopAntenna
  • Yo-Yo Antennas & various Longwires
  • Extended AM Ferrite Rod for PL-365/360
Slinky, ST3 Scanner Antenna (EB2100 on top of the wall unit library)

Okay, so what is my “listening post”?  It’s a sitting room attached to my master bedroom.  I have a roll-top desk.  A slinky antenna stretched across one side of the room above the window.  And an ST3 “Sputnik” Scanner Antenna hung in front of the window (for my RadioShack Pro-651).  I use an old-school iPad 1st Gen next to my radios because I found that it emits virtually no RF compared to my iMac, MacBook Air, and MacBook Pros.  Besides using the iPad Gen 1 as an Internet reference, it’s also loaded with every one of my radio & antennae manuals, nearly every copy of Passport to World Band Radio, and many Spectrum Monitor issues.  If I cannot find a pdf version of a manual, I use my document scanner to create my own pdf’s.

Typical set-up (the metal basket bin is completely filled with radios, antennae, adapters, etc., all in their own cases)

Having my listening post essentially in the master bedroom causes conflict because my wife must get up early & drive 60-miles to work thus I am kicked-out and banished downstairs fairly early each night … while carrying a radio or two with me if I wish to continue listening.  Nearly all of my shortwave listening occurs before 8:30 P.M.

I have all of my radios and antennae neatly organized in padded bags & cases within an arms reach of my roll-top.  Since everything is organized in its own case, I can easily grab whatever combination I want if I were to travel (or go outside, or go downstairs when my wife kicks-me-out of my listening post).

What are my favorites?  I typically use the Grundig Satellit 750 the most – mainly because of its size & large intuitive buttons.  The direct BNC connections make it quick & easy to transition from one antenna to another.  My favorite SW radio feature is Tecsun’s ETM (I wish every radio had it) thus I find myself using the PL-390 & PL-365 especially when out of my listening post.  My favorite antenna is the TG34.  I find that it greatly enhances the signal with a minimal increase in noise.  The Slinky is great in that I can add it to another antenna that I’m using to make a more effective combination (e.g., AMECO TPA with the Slinky & the NASA PA30 with the Slinky on the radio whip work well for me).

The bins and black cases with my gear (those are two Plano Gun Cases … a 2-gun case and a 4-gun case; I have 8 more filled with my astronomy gear but that’s another story).

I think shortwave listening is a great hobby that compliments my amateur astronomy.  Why?  No matter the clouds, extreme temperatures, etc., I always have something interesting to do.  But I do miss the days when the wave bands were crowded with international broadcasters.  At least I know that Jupiter, Saturn & the thousands of deep sky objects within grasp of my many telescopes & binoculars will NOT be leaving the sky until long after I leave this planet!

You’ve set up an excellent listening post, Troy! As you well know, I’m a bit of a pack junkie, so I love the fact you have so many padded cases and protective gear for your equipment–no doubt, this is championed by your amateur astronomer half!

SWLing Post readers might recall that, last year, Troy actually put together a shortwave broadcast dedicated to amateur astronomy. We published a full recording of the show on the Shortwave Radio Audio Archive.

Thanks, again, for sharing a tour of your listening post, Troy!

The new CommRadio CTX-10 QRP general coverage transceiver

commradioctx-10

Many thanks to Fred Osterman and Dave Zantow for sharing information about the new CommRadio CTX-10 transciever.  Here is the description from Universal Radio’s catalog:

AeroStream Communications near Golden, Colorado entered the hobby radio market in 2013 with their revolutionary CommRadio CR-1 and follow up CR-1a SDR receivers. The success of these innovative radios left many asking for a transceiver of similar size and capability.

The answer is the just announced CTX-10.

The CommRadio CTX-10 blends high performance, internal SDR technology, high efficiency circuit design, compact size and simple operation. This multi-mission QRP radio is ideal for field use and emergency operations. Transmitter covers 160-10 meter amateur bands with output power adjustable from 1 to 10 watts. The new design uses ruggedized land mobile power amps in push-pull. Every aspect of the radio design is optimized for low power consumption.

The efficient and sharp OLED display is readable in low or high lighting conditions. The radio has three built-in #18650 3.7V 2600 mAh Li-ion batteries providing 28.8 watt-hours of operation. A built-in intelligent charger provides seamless power management.

The general coverage receiver section uses multiple preselectors for optimized reception from 200 kHz to 30 MHz. An integrated CW reader and antenna tuner enhances portability. The premium tuning knob optical encoder is rated at a million revolutions.

Entire enclosure is aluminum with metal knobs and front panel. External connections are through-hole mounted for durability. Includes USB cable, DC power cord and manual. DC power requirements: receive 1.5 W, transmit 20 W. This quality device is robustly built in Colorado, U.S.A.

I’m really looking forward to reviewing the CTX-10. If the CR-1 and CR-1a are indicators, this could be a very well-built unit with a top-notch receiver!

Follow the tag CTX-10 for updates.

Oxford Shortwave Log: 200 metre Beverage antenna – initial reception tests

beverage3

Hi there, I have finally deployed the Medium Wave Circle-design 200 metre Beverage antenna (schematic diagram above) at the woods I use in Oxford, UK. It was terminated at the ‘front end’ with a 650 Ohm resistor into a 1 metre-long, permanent copper earthing rod that I had previously driven into the ground, away from the route taken by the general public. The actual wire was orientated in a generally westerly direction, and thus nulling signals propagating from the east. At the receiver end, I utillised my self-built transformer, wound for a 50 Ohm input impedance (14 turns on the primary), thus making the entire set-up suitable for the Elad FDM DUO. It was quite a pain to set up, taking over an hour to deploy the wire and connect both earthing rods and the transformer! However, intial results are very promising and here I am very pleased to share 3 reception videos with you:

The reception from Colombia and Ecuador was unprecidented and both of these tropical stations sound like local AM signals, aided of course by the Bose SoundLink Mini 2 (the Elad’s stand-alone audio is puny to say the least). The signal from Peru is weak, as would be expected, however, the low-gain/ high SNR performance of this antenna results in audio clarity that is better than I have ever heard previously from this rather exotic station. Further to these recordings, I managed to make two recordings of the entire MW band using the FDM DUO via the FDM-SW2 software and I’m hoping an analysis of the data will uncover some nice MW DX. Thus, all-in-all, a very good result with the 200 metre Beverage – more reception videos using this antenna to follow soon on my youtube channel Oxford Shortwave Log. Thanks for watching/ listening and I wish you all good DX.

Embedded reception videos with text links follow below:

Contest Reminder: Your “dream radio”

dial_closeup_1

Think back to your first days in radio…What was your “dream” receiver?  And why?

Or–if you’re new to shortwave radio–what is your “dream” receiver currently, and why?

Many of us had a radio they dreamed of in their youth, or when they first began to hanker after the radio experience. What was yours?  For newer hobbyists, what is yours? And just what made–or makes–this radio so special? Did you ever obtain one?  And if so, did it live up to your expectations?

Share your experiences with the Post for a chance to win a prize from Universal Radio!

The winners of this contest will be chosen at random, using a randomizer application; an independent non-entrant will make these selections.

Thanks to Universal Radio and Fred Osterman’s generosity, there will be two winners of this simple contest–a US winner and an international winner.

The US prize will be a copy of Shortwave Receivers Past and Present by none other than Fred Osterman. I reviewed this book a couple years ago: it is an invaluable reference tool and also a fun “dream” book.  With sincere apologies to my international friends, this prize must be limited to the US simply because shipping this weighty volume internationally would cost more than the book itself.

ShortwaveReceiversPastAndPresent

The international winner may select between the following (less weighty!) books, also very good references: Joe Carr’s Loop Antenna Book or Buying A Used Shortwave Receiver: A Market Guide To Modern Shortwave Radios.

Entering the contest is easy. Simply go to our entry form (below or click here) and fill in the required fields.  Be descriptive! This will make the contest fun. Let us know in detail why that radio was (or is) so significant to you.

Your entry will be recorded, and the winners chosen at random on Sunday October 16, 2016. We’ll publish the responses once the contest concludes, sharing only the name you provide.

Radio Maubere: clandestine radio in occupied East Timor

Radio-Dial-Blurred-Dark

Many thanks to SWLing Post contributor, Phil Brennan, who writes:

Your readers may be interested in this article detailing a clandestine radio station that was set up between the Fretlin rebels in East Timor (now Timor Leste) and supporters based in Darwin where I live. The Fretlin rebels fought against the Indonesian occupation until the country’s independence in 2002. In the 1970s this was the only method of obtaining information on the brutal repression of the Timorese people by the Indonesian dictatorship

The man featured in the article, Brian Manning Snr., who died a couple years ago was a well known activist and trade unionist in the Northern Territory. He was also very involved in the campaign for Aboriginal workers to receive equal pay and conditions in the 1960s. This campaign was instrumental in raising the profile of the Aboriginal land rights movement in Australia. Brian Manning Jr. Is a good friend of mine.

(Source: ABC News)

If someone was to make an Australian version of Forrest Gump, they might look to Brian Manning’s life story for inspiration.

In 1966, he helped the Gurindji strikers in the Wave Hill walk-off. When Cyclone Tracy hit his hometown of Darwin, police commandeered his truck to collect dead bodies. Months later, he became involved in possibly the most important mission of his life.

That mission was Radio Maubere: an underground radio link that operated between Darwin and occupied East Timor during the 70s and 80s.

For many years, it was the only link the Timorese had with the outside world.

“Dad felt very strongly that these people needed to be supported in their struggle,” his son, Brian Manning Jr, said.

“So with a few other people, they got together and formed this radio operation.

“It was vital. There’s no doubt that the Indonesians were in there to systematically reduce the population by any means necessary.

“So these people were just killing people, and these stories had to get out.”

[…]As the years went on, and the list of confiscated radio transmitters grew longer and Manning’s tricks became more and more creative.

“They had a few decoy vehicles. And they had a few decoy radios. And they had people rendezvous with them in the bush in certain areas,” Brian Manning Jr said.

Often one person would set up the transmitter, another would come along and use it, and a third would arrive to pack it up and transport it out of danger.

[…]The broadcasters even devised their own coded language to communicate top secret information, remembers one of the group’s members, Robert Wesley-Smith.

“They each had a book, and the code would direct them to a page or something. It was very slow … but it was a great adventure,” Mr Wesley-Smith said.

Whatever problems Manning and his crew had in Australia were nothing compared to the dangers faced by those operating on the other end, where gunshots could sometimes be heard in the background.

There was a constant need to get new transmitters into the country, and an engineer from Sydney came up with an ingenious method for avoiding detection.

“It now fell to the resourcefulness of Andrew, who created a transmitter out of a ghetto blaster,” Manning wrote in his book.[…]

Dave warns of fake “Sony SW-33” receivers

Fake “Sony SW-33”

Many thanks to SWLing Post contributor, Dave Zantow (N9EWO), who writes:

Here is an interesting one [I saw] on eBay this morning. A SONY marked SW33 SW portable, but of course it’s NOT the ICF-SW33 model you (or I ) are thinking of.

Click here to view on eBay.

Looks to be a Kchibo made radio (a model I tested for Passport years ago) ? Humm….but Kchibo’s are made by TOWADA Audio (in China and Vietnam plants). As you may already know TOWADA Audio also made all of Sony’s SW sets for decades going back into the 70’s (but at the Japanese Plant of course). So is this some unofficial model (but poorly marked) or just a total fake from a few years ago ??

Have more information on TOWADA and Sony on the bottom of my Sony Page : http://webpages.charter.net/n9ewo2/sony.html

But that is a weird one.

Thank you, Dave! Yes, obviously this “SW-33” is not the real item (see authentic ICF-SW33 above).

I’m guessing the seller has no idea this is a fake radio. Dave makes a good point: if it doesn’t look like a Sony, it probably isn’t! Buyer beware.
