Have you ever installed a covert shortwave radio antenna?

Yesterday, in a comment thread, SWLing Post reader Dan described a covert antenna he once installed in a student apartment:

I’m waxing nostalgic now, but I had a great set-up for a couple of years back in the ’70s. The receiver was a black WW2 Navy surplus Hammarlund RBG CHC-46140. (I still have it).

I was a student living in an apartment on top of a two story, wood-framed apartment building. The attic access for that building was from the ceiling of the wardrobe closet.

During a Christmas break I was probably the only occupant of the building. I snuck into the attic and installed a set of five switchable dipoles. I had a good 60′ of space to work with and the antennas were broadside to the southwest. This was quite a memorable listening post.

When I moved out, I cut the coax to the dipoles and used toothpaste and borrowed pieces of “cottage cheese” to fill the five holes in the ceiling. Those antennas are probably still there.

Indeed, I bet they are still there, Dan!

In reply to Dan’s comment, Walt Salmaniw, noted:

Dan, reminds me when I was stationed in Germany in the early 80’s.

We lived in old French officer’s quarters. Basically, 4 story buildings with the upper floor/attic uninhabited.

I put up some nice 60 m dipoles in that space, with a goal of hearing a lot of tropical band DX, which I did using my Kenwood R2000 receiver.

Those were the glory days of dxing!

Thanks, Dan and Walter, for sharing those stories. The thread reminds me of a post we published sometime back where one young listener installed a wire antenna in his home while his parents were away. (I can’t seem to locate that post at the moment for a link!).

Though not nearly as elaborate as Dan and Walter’s antennas, I did install a small covert antenna once myself.

In the early 90s, I lived in Grenoble, France, in a four bedroom house in which three bedrooms were occupied by university students. The landlord was a rather fussy elderly woman who lived on the ground floor. I never dared ask her if I could string a random wire outside my top floor bedroom window. Though she was mostly fair and even sweet at times, I knew what the response would be if I asked for permission: a firm “Non.”

One night, I opened the bedroom window and carefully connected a short wire antenna to a nail on the side of the house, above and slightly to the side of the window. I had to stand on the window and hang out of the house to do it.

The Realistic DX-440

The antenna dangled there the whole year I lived in that room and served me quite well. I’d simply open the window and clip it to my Realistic DX-440. I did remove the antenna before before I moved back to the States, but it was virtually undetectable against the exterior wall of the house.

Other covert antenna installations?

Please comment if you’ve ever installed a hidden antenna as well. (I love this stuff!) Besides…who knows…your antenna might benefit someone in need of a hidden antenna today!

New Shortwave Station in South Sudan

4 Replies

There’s a new shortwave station in South Sudan!
Kudos to Eye Media for their Shortwave Radio efforts in South Sudan to complement and extend their reach beyond local FM radio. And I must add, kudos to the United States for their part in helping to fund the venture. While I am quick to criticize my country for their cutbacks in SW funding, I have to be fair and say “well done” when something like this comes along. Here is the news report as posted April 26 (yesterday) on Radio Tamazuj and which was reported by Alokesh Gupta New Delhi on the Cumbre-DX Yahoo Group:

Eye Media, the parent organization of Eye Radio, has announced that it has launched a new shortwave broadcast service to complement its existing FM broadcasts in South Sudan.

The broadcasts starting today will bring listeners news and information in Arabic, as well as Dinka, Nuer, Shilluk, Bari, Zande and Lutoho.

According to a press release today from Eye Media, “the Eye Radio Shortwave will cover the whole of South Sudan including remote areas in which communities are not able to access FM radio stations.”

Eye Radio is one of the fastest expanding media houses in South Sudan after launching FM repeaters in several state capitals last year, expanding the station’s reach beyond Juba where it is based.

In its press release, the station noted that the funding for this initiative came from USAID, the international development agency of the US government.

Shortwave radio is used for long distance communication by means of reflecting or refracting radio waves back to Earth from the ionosphere, allowing communication around the curve of the Earth. It was a popular means of long-distance news sharing before the advent of the Worldwide Web, and it is still used for reaching remote areas.

Only two other media houses broadcast on shortwave with content specifically for South Sudan: Radio Tamazuj, which operates two hours daily on the shortwave, and Voice of America, which produces the 30 minute program South Sudan in Focus.

Radio Tamazuj broadcasts from 6:30 to 7:30 each morning on 11650 kHz on the 25 meter band and 9600 kHz on the 31 meter band, and 15150 kHz and 15550 kHz on the 19 meter band each evening from 17:30 to 18:30.

Eye Radio’s new broadcasts will run from 7:00 to 8:00 each morning on 11730 kHz on the 25 meter band and 17730 kHz on the 17 meter band from 19:00 to 20:00.

Mark’s rekindled interest in shortwave radio

Many thanks to SWLing Post reader, Mark Lane, who writes:

Hi Thomas,

I just wanted to thank you for a great website, I have been interested in SW since I was a boy and used to listen to my grandfather’s world radio. I cannot remember the make or model now but it was an amazing experience.

After all these years, at the age of 44, my interest perked again and I happened across your site.

Like a lot of people I was wondering “is there anything left to listen to on SW now we are truly in the ‘digital’ age”? After reading the content on your site and the blog I made up my mind, jumped onto eBay and after a number of failed attempts at winning any auctions I managed to bag a near mint Sony ICF 2001D [photo at top of page]!

I did get rather over excited and probably paid a bit too much for it, but too be honest I don’t care. I have already had a good couple of evenings trying to bag some far off stations and I am still trying to figure out all the buttons on the thing.

Then this past weekend, my daughter (15) asked about the radio and I showed her what I had been doing–she was hooked and kept asking me to try for some more stations. We spent the whole evening with the help of a couple of other websites trying to track down more distant stuff.

I have to say the 2001D is now my prize possession and my daughter was messaging her friends telling them all about the wonders of SW.

All I can say is keep up the good work and let’s hope SW does continue for as long as possible I will certainly be listening in until the airwaves go quiet, I trust that won’t happen for some considerable time.

Mark: thank you so much for sharing your message! It’s an honor to know that the SWLing Post played some part in your renewed interest in shortwave radio. The community here is simply amazing and I learn a lot myself from so many reader contributions.

Being a father of two daughters, I can say that there’s no better feeling than to know that a little radio listening time also translated into quality father and daughter time!

You just made my day!

Alan seeks help modifying the NewLog logging application

SWLing Post reader, Alan Lever, writes:

“Although not new, NewLog is excellent for all breeds of radio listener.

It has separate opening screens for Amateur, SWL, Broadcast etc. all fully adaptable as to layout, renaming boxes etc.

The developer, Tom Lackamp (AB9B), gives full permission to alter and further develop it. I’ve had no success contacting him.

To make this program perfect, can anyone tell me how to set up drop boxes in the various set boxes. I have no idea how to do this myself so would appreciate any help, please.

Readers: Please comment if you can help Alan modify NewLog or if you have current contact information for the developer, Tom Lackamp (AB9B). Thanks!

Recordings: Paul records Vanuatu and Solomon Islands from central Alaska

Many thanks to SWLing Post contributor, Paul Walker, who shares the following recordings of Radio Vanuatu and the Solomon Islands Broadcasting. Paul lives in Galena, Alaska, and records most of these broadcasts outside of his broadcasting studio:

7260 kHz:

5020 kHz:

3945 is much weaker then 7260 for some reason and Nikkei is on that channel till 0900 UTC, so about the only chance I have of hearing Vanuatu on 3945 CLEARLY is when Nikkei signs off.

9545 kHz Monday Night 1130 AKDT/(0730 utc Tuesday)

https://soundcloud.com/paul-walker-11/9545-april-25-2016-11-21-37-pm

7260 from April 19th at 1135 AKDT /0735 UTC)

5020 from April 20th at 1248 am AKDT/0848 UTC

Thanks for sharing your recordings, Paul! You’ve certainly done a fine job DXing in the northern latitudes all while standing next to a broadcast station.

Keep up the great work!

Curating a list of endangered shortwave stations

2 Replies

That’s my minivan parked in front of the RCI Sackville transmitting station in June, 2012. The site was closed by the end of 2012 and towers demolished shortly thereafter.

Recently, my friend and fellow archivist, London Shortwave, and I engaged in a discussion about creating a curated list of “endangered” shortwave radio stations.

The idea being we could use such a list to focus our efforts and those of the archiving community on recording broadcasters that were most likely to disappear in the near future.

London Shortwave published an excellent post about this on his blog.

Please click here to read his post.

We quickly put this page on the Shortwave Radio Audio Archive as a starting point.

We need your help to curate this list!

Please comment either on London Shortwave’s blog, or on this post, and suggest any additional broadcasters we may have missed. Please include a link to news item(s) which may indicate the broadcaster faces closure.

Of course, this list and the categories are subjective–we’re simply using our best judgement in this process. Often, broadcasters can shut down with little or no notice.

Thanks in advance for your help!

Off-Grid Radio: Portable power recommendations?

5 Replies

This year, I have a lot of portable radio play in mind as I travel across the continent. At some point, I even plan to spend several days in an off-grid cabin on the coast.

In the past, I’ve powered my 12 VDC ham radio transceivers with a system comprised of three PowerFilm solar 5 watt foldable PV panels (see below), a Micro M+ charge controller and several gel cell type sealed batteries (a couple 7 Ah and one 20 Ah).

The system works well, but the batteries are a little heavy and unhandy when I want to hike into a remote site or play radio on the beach, for example.

In terms of receivers, my portables (like the Sony ICF-SW7600GR, Tecsun PL-660, etc.) simply use AA batteries which I charge with PowerFilm AA PV chargers (see above). My CommRadio CR-1a has an internal battery that will power it for hours at a time.

Power is much less of an issue with receivers because they’re quite resource efficient.

I mainly need a system to power my QRP ham radio gear, and that’s where I could use your experience!

Wish list

Charge controller

I need a new charge controller since my Micro M+ (no longer produced) is now being used to power a remote antenna tuner.

Of course, I’ll need an inexpensive charge controller that doesn’t produce RFI (radio interference).

It would be an added bonus if the charge controller could also charge my batteries when grid power is available.

12 VDC Battery packs

I’d like something relatively lightweight and safe.

Note: LiPo packs worry me, especially since I had one (an early GoalZero model) quite literally melt down and burn up on my bed only a few hours after bringing it back from an eight hour flight a few years ago. Scary!

Pure Sine Wave Inverter

I’d also like a small, efficient pure sine wave inverter that I I could connect to my largest battery and power my laptop for extended SDR spectrum recording sessions while off-grid.

I’d love a recommendation from someone who uses one and can confirm a model that doesn’t create radio interference while operating.
