As I suspected, the unidentified broadcast I recently posted was the Chinese jamming service, Firedrake.  Thanks to all who confirmed.

Mark Fahey even commented with a link to an article explaining how he made a studio recording of Firedrake from Chinasat 6B. Read Mark’s article here.

Mark also has the full 60 minute studio copy of Firedrake available as a 90MB MP3 file.

In my recent post, The truth about portable amplified shortwave antennas, I argue that small, portable amplified antennas are, by and large, ineffective. The post comments are interesting, however; many readers agree, and some tout the Sony ANT-LP1 as worthy, but Mike made the following comment about his amplified antenna:

The one active antenna that I have been pleased with is one I built myself.  The design was by ON2NLT and uses a ferrite rod, so it is somewhat directional.  Rotating the unit (it is very compact) often allows nulling out noise or interference.  You have to be careful not to crank up the gain too much though, or you will amplify the noise floor.  The link is here

Looks like a fairly simple project.  Thanks, Mike!

Dave’s FM station empire

FMMegaplexDave Schmarder (N2DS) enjoys making radios and featuring them on his website, http://makearadio.com. What you may not know is that he also runs his own FM stations empire…and you can too:

I thought your visitors might be interested in my FM stations empire. I bought a bunch of mp3 players with built in fm transmitters that are usually used in a car and adapted them for home use. They all cost me under $4 each, plus a TF card for a couple bucks for each music transmitter.

At the moment I have 8 transmitters running, mostly with usb sticks looping music, but also a transmitter hooked to my tv cable box and another one to my internet radio.

This allows me to be anywhere in my little house and listen to these audio sources using a small Tecsun FM radio. During the summer I could sit on my porch and listen without dragging my radios or iPad outside.

Perhaps some of your visitors might be interested in having their own fm radio megaplex. Here is the link: http://www.n2ds.com/musiccenter/musiccenter.htm

73, Dave

Thanks, Dave!

I’ve often thought of broadcasting 1930’s and 40’s music over a micro shortwave transmitter in my house. I would love to know if any readers have done this. Admittedly, it would take a pretty committed shortwave radio geek. Anyone? Anyone?

The truth about portable amplified shortwave antennas

In the past week, I have had no less than 3 email inquiries from readers regarding which amplified antenna to purchase for their portable shortwave radio.  My short answer? None.

In my opinion, there’s one fatal flaw with amplified antennas: they amplify noise just as much as they do the signal you wish to hear.

The Sony AN-LP1 is the best amplified antenna I've ever used, but that's not saying a lot.The only portable amplified antenna I’ve had any results with is the Sony AN-LP1 (now only available in Japan), and I attribute this success mainly to the fact that a suction cup, mounted at the top of the loop, allows it to be mounted on a window. Even then, results are often only marginally better than with the telescopic whip.

There may have been a time when portable amplified antennas made sense–a time prior to noisy AC adapters, flat screen TVs, and other consumer electronics which spew RFI (Radio Frequency Interference), polluting our shortwave bands. Today, however, you’ll be disappointed with the results of one of these, particularly if you travel–turning on the amplified antenna in a hotel room will increase the noise you hear two-fold, while weak broadcasters will remain lost in the static.

RollUpAntennaReelSangean

The Sangean ANT-60 is inexpensive and vesatile

So what can you do to improve the performance of your portable while traveling or at home? I’m still a fan of the roll-up antenna; like the Sangean ANT-60.  They’re inexpensive ($12 US), packable, and versatile–the clip on the end of the reel allows the antenna wire to be clipped to curtains and blinds. Place it near a window, or even hang it outside. Antennas love being outside–just take it down when not in use.

In lieu of buying a roll-up antenna, you could simply attach an alligator clip to the end of a 20′ (6 meters) length of wire.  The alligator clip can then attach to the end of your telescopic antenna, and you now have the same properties of a roll-up antenna for pennies. This is possibly the most cost-effective way to improve the performance of your portable shortwave radio. One note of caution: don’t get too generous with the length of your antenna wire. Some portable radios lack a robust front-end and a wire that’s too long could actually overload the receiver. Some Grundig G5’s were even sensitive to static discharges over a wire antenna. If uncertain, I would not exceed 20 feet in length (6 meters).

An alligator clip offers serious bang-for buck--especially if you already have the parts lying around

An alligator clip offers serious bang-for buck–especially if you already have the parts lying around!

I’ll never forget:  one of the first email questions I received on SWLing.com was from a fellow listener in Washington state who wanted to hear stations better on his Sony portable. I suggested the alligator clip/antenna wire. He wrote back enthusiastically, “This is the most cost-effective improvement I have ever made to anything!” He was so encouraged with the performance improvement, he invested in a tabletop and a proper outdoor antenna with grounding.

So, I urge you to try a roll-up antenna or the alligator clip antenna before you waste money on a portable amplified antenna.  Just my two cents.

Vlado’s thrift store find: A Sony ICF-2010

The Sony ICF-2010

Vlado’s Sony ICF-2010 (Click to enlarge)

While visiting my friend, Vlado, this weekend, he showed me his thrift store find: a Sony ICF-2010 in very good condition`. The ‘2010 is a well-known portable amongst serious DXers, and is highly sought-after. Since this radio has not been in production for many years, used models routinely sell for a price in excess of $200 US. Parts radios sell for $50 US or more.

We suspect that the previous owner thought it stopped working. You see, when Vlado plugged in the AC power adapter, nothing happened.

But take note: there is a quirk, at least with some ICF-2010s–they will not power up, even with the AC adapter plugged in, if you don’t have AA batteries installed. Indeed, two AA cells are required for either DC or 120 VAC operation. Once Vlad put AAs in, the radio came to life.

How much did  he pay for his Sony ICF-2010? Five dollars.

Paint me envious!

“The era of short-wave radio is behind us” and other inaccuracies from the new RNW

RNWRNW announced “A new Radio Netherlands Worldwide” just yesterday on their website; here is their announcement in its entirety (my comments follow).

<><><><><><>

“This coming year is an important one for RNW. A year in which, at the age of 65, we will be reinventing ourselves. Our new Editor-in-Chief William Valkenburg officially begins today; he looks to what lies ahead of us in 2013.

“The era of short-wave radio is behind us; satellite and Internet are the communication channels of the future. The worldwide dissemination of information is no longer the exclusive domain of specialised broadcasters. Via internet, anyone anywhere can reach out to the world with a good story.

“That doesn’t mean journalists and broadcasters are redundant; quite the contrary in fact. Huge amounts of information are available more and more quickly and via all sorts of different channels. The need to filter, analyse and investigate all this information remains the same while the goalposts of journalism have moved completely.

Active link
“Our public is no longer a passive audience that very occasionally might write us a letter, but an active link in the process of newsgathering and distribution. Our public engages actively in discussion and has stories that are worth telling. They help us filter by letting us know what is or isn’t relevant to them. And via social media, our public spreads our best stories further abroad.

“RNW will have to forge a strong and unique identity if we are to win a place as a visible force in the new media landscape. Focus and specialisation are key. Free access to information, freedom of expression, good governance, and civil and sexual rights are the pillars of the new RNW: universal themes we’ll be tackling with an individualistic Dutch approach. We’ll be focusing our work in areas where freedoms are limited and aiming to appeal to a younger generation that is increasingly tuned in to new media.

New stories
“2013 is Year Zero for the new-look RNW. A year in which we’ll be looking more than ever to strengthen cooperation with our partners and audiences in China, Latin America, Africa and the Arab world. A year in which we’ll be actively looking for new ways to find and tell the stories that are important to our audience, and in which our audiences will be encouraged to play an ever more active part. A year in which we’ll be pushing ourselves to cement the ties with our audience and our themes. A year, in short, of dialogue and renewal.”

<><><><><><>

And, unfortunately, of short-sighted misstatements and errors. No doubt, SWLing Post readers know how we feel about this–it’s a recurrent theme in many of our posts.

Shortwave is not behind us, but RNW’s ability to listen may be.

As a shortwave radio broadcaster, RNW arguably had a dedicated listener pool in the millions. Of course, it’s hard to know, because those living in poverty and those living under repressive regimes–millions of listeners–who lack free internet access and whose free speech is regularly quelled, don’t have the ability to cry out, “We’re listening–!”

Millions of ears are still tuned to the static you recently vacated. Outreach in all forms–even via shortwave–is vital, and communication with those still without Internet or freedom (or the voices to tell you so) is a form of diplomacy more valuable than any money spent to achieve it.

RNWin2013Perhaps host of the previous RNW’s acclaimed program The State We’re In, Jonathan Grubert, had a point when Jonathan Marks interviewed him on the night of RNW’s final shortwave broadcast. Marks asked if RNW had stayed on shortwave too long, to which Grubert responded by saying, “Yeah, I think Radio Netherlands stayed on shortwave too long.” I think Grubert believed that RNW had remained faithful to shortwave at the expense of resources required for other contemporary and future media. And at the expense of their future.

As much as we hate to admit it, he was probably correct…in part. The fact is, the previous incarnation of RNW should have focused on making their shortwave broadcasting arm more lean and efficient, in order to continue to target parts of the world that need it most, while diversifying their media delivery systems to include the Internet, satellite and wireless in all forms. Instead, the organization failed to adapt, and funds were cut completely, leaving RNW gutted. But the lesson is apparently not learned:  the new but-not-proved RNW seems to be putting all its eggs in one (Internet) basket, as well.

Indeed, this is the problem with shortwave broadcasting in general.  Many broadcasters developed their transmission infrastructure either during WWII or in the Cold War, when countries were willing to invest vast sums of money in order to have their national voice heard. Broadcasting sites were never intended to be efficient: resources were either cheaper when the services were initiated or efficiency simply was not a concern in the days before fiscal cliffs.

Today, it’s true that shortwave radio is on the decline in many parts of the world, particularly first-world countries. In the great pie chart that represents all of the content delivery systems an international broadcaster has at their disposal, the shortwave slice should be thinner, while Internet and wireless-based systems must also be included. Diversification is key.  Indeed, I would also argue that a small, separate slice of the budget should be reserved for future HF content delivery systems–such as innovations that are based upon the shortwave radio medium and existing infrastructures. We’d like to think that many are doing this now. After all, shortwave is still the only international communications medium that is resilient to jamming and thus to censorship.

What’s obvious is that shortwave is still highly relevant to those who rely on it, just as the Internet is crucial to the future of international broadcasting. There’s a false dichotomy in the “shortwave vs Internet” argument, and broadcasters and the governments that support them are fooling themselves if they think cutting shortwave will lead to their fiscal salvation and a promised future in new media technologies. One might as well argue the relative merits of wealthy versus poor, or of first world nations versus third because that’s where the divide takes place…Does the former have more “right” to information than the latter?  “Free access to information, freedom of expression, good governance, and civil and sexual rights are the pillars of the new RNW.” Already, the first “pillar” of RNW is crumbling under its complete dismissal of shortwave–a tested and effective international content delivery system that requires no subscription and streams at the speed of light.

We found at least this statement from their announcement to be accurate:

“RNW will have to forge a strong and unique identity if we are to win a place as a visible force in the new media landscape…”

In order to achieve this goal–namely, to actively engage a global audience on the “new” world wide web–RNW will need spectacular content created by exceptional talent–much like they had only last year, that is, before they incomprehensibly severed it. As much as we want to believe that Radio Netherlands will continue to have something to contribute to the media landscape after shutting down their shortwave service and gutting their resource pool of talented and dedicated journalists, we’re deeply, profoundly skeptical.  To say the least.

Why? They’re nearly two decades late to this game. Obviously, the Internet is no longer a “new” media landscape; it’s absolutely saturated with content and communications innovations. RNW has dispensed with the one thing they might have brought to the Internet–their programming. Once we learned that RNW was going to cut The State We’re In–an award-winning program, arguably RNW’s most popular–we knew RNW wasn’t making logical goal-based decisions to mark their place in future media.  RNW’s claim that it will “forge a strong and unique identity” in the face of cutting all that made it respectable, listener-worthy and unique, shows a decided lack of judgement…a lack of direction.

RNW, no one is going to listen if you’ve nothing worth hearing. We hope you can find what you’ve lost–your talent, on the one hand, and millions of listeners, on the other.  Connected via radio.
