Adventures In Amplitude Modulation – Part 13

Monday, March 27th, 2006

2010_1 This episode of this series continues from my evening of scanning the shortwave bands March 1, 2006. This time it’s the next hour and the next band. This is the 41 meter band (7100 to 7350 kHz), another popular chunk of the shortwave frequencies. Again, this recording is an unedited slow motion frolic through the signals using my BCL-2000, sitting at my kitchen table in Brooklyn.

And I want to again thank reader Ralph who contributed some edifying comments in last week’s post. Now I have a better grasp on tracking down “images” of stronger signals which pop up on nearby erroneous spots on the dial. This is perhaps the greatest fault of the BCL radios, and an inherent problem in single-conversion radios in general. Dual conversion sets effectively filter most images and are generally a bit more expensive.

A couple years ago, when I was shopping around for a higher end old portable I was scouting ebay and I had pretty much decided I was going to hunt down one of two classic receivers– the Panasonic RF-2200 or the Sony ICF-2010. Both are discontinued, and in good shape they generally go for about the same price on ebay– about two-hundred bucks (although a mint 2010 in its box could go for a hundred or two more). My analog instincts led to me to go after the RF-2200 and I don’t regret it. It’s a hell of a rig and it pulls the weak signals out of the ether, and is a great radio to DX the AM band. It’s also dual-conversion. However, after the 2010 was mentioned once or twice in the comments section here, it’s gotten me to take a second look at it. The 2010 is not as nearly as handsome the 2200 and doesn’t have that golden glow of frequencies, but I’ve come to realize that the 2010 is just one amazing device. And now my gadget lust has launched a little feedback loop in my radio heart. I want one. I really want one. However, I really don’t have the cash handy right now. But I’m looking at ‘em on ebay… Someday. You can read some reviews of this mighty little digital gadget here, here and here. It’s 1984 technology that Sony happened to really get right (It was manufactured for almost 20 years!). However, If you’ve got some cash on your hands and you want something new, many think the new Eton E1 improves on this radio’s legacy.

Clandestine_gear_1 Before I go on to the band scan for this week, I wanted to mention a few (free) podcasts that may interest readers of this blog series. Clandestine Radio.com offers “Global Crisis Watch” (XML feed here), a program reporting on (and promoting) democracy movements around the world. It’s a rather urgent show featuring interviews of journalists, broadcasters and activists involved in fighting oppression around the world. And of course, there’s some good information on shortwave and other radio broadcasts from time to time. It’s an interesting half hour delivered to your hard drive every week. The Global Crisis Watch is a cutting edge international news put together by a couple of guys instead of a government or corporation.

Although not many are aware of it, there’s quite a bit of pirate radio activity on shortwave and the podcast “Pirates Week” (XML feed here) offers a weekly overview of that scene. This podcast varies in length and is a much more loose and light affair than Global Crisis Watch. It’s an amalgam of many related diversions– discussions of assorted radio gear and computers, details of the realities of seat-of-the-pants broadcasting, as well as clips of shortwave pirates at play and tips on where and when to find ‘em on your radio. Also the Mediageek has a well-kept and extensive blog and podcast (RSS feed here) where he explores all sorts of media products, broadcasting trends, and the inherent toys that make it all possilbe. And his most recent podcast features an interview with Ragnar Daneskjold, the host of “Pirate’s Week." According to Ragnar, a nice warm illegal transmitter running 40 watts on shortwave can give you coverage of most of the U.S. on a good night. Hmmm…

Glenn_hauser Also, the ultimate source of all things shortwave is Glenn Hauser. The guy is dedicated. His “World of Radio” program, which broadcasts on quite a number of shortwave stations, is also a podcast (XML feed here). While not high in entertainment value, it’s a helluva dose of up-to-date shortwave news, views and frequency listings. On his World of Radio site, as well as his weekly “DX Listening Digest” Mr. Hauser puts out some great web resources which provide valuable information for mega-geeks and weak-kneed newbies alike. And it’s all listener and reader supported!

Okay, on to this recording of reception on the 41 meter band . Actually, this scan begins just before the that band and then traverses up the numbers. The frequencies are in kilohertz. It’s Wednesday night, March 1st and Bush is over in Asia eating Indian mangoes I think. It’s early evening here, one of the best times to catch foreign broadcasters offering up English language programming for the Americas (and Spanish ones too for that matter). And more importantly, at this hour the band isn’t a kooky Christian radio ghetto yet. Closer to midnight and beyond the shortwave bands are flooded with hallelujah bullshit and not much else, at least not in English. But at 0100 UTC (all shortwave schedules basically follow the time in London, and in a 24 hour manner), which is 8 pm Eastern Standard Time, the biblical blather is only part of the mix, not the dominant force.

Actually, this begins right before eight, a fine time to start a band scan. Let’s begin.

Segment 1-41 Meter Band (6875 to 7300 kHz) 03-01-06

6875 EWTN Global Catholic Radio Network

It’s right before the top of the hour, 8 p.m. here, 0100 hours UTC. Most international shortwave stations play something called an “interval signal” in between programs, an identifying snippet of music that may include other sounds or the official ID of the station. Listening to shortwave you begin to get familiar with the these little ditties because they usually repeat for a couple minutes right before a new program ensues, and can help listeners ID a station as well as find a particular program on the dial before it begins. Interval signals almost always come at right before the top of the hour, and occasionally precede the 30 minute point as well.

Pope_internet_i_2 So, this clip begins with the EWTN’s official and soothing interval music and then their ID. This site has a huge archive of interval signals past and present. They all stream in real media. Pretty cool. I was slightly thrilled to find this one, the interval signal of Radio RSA from the 1970′s– a chirpy bird with folky guitar. This took me back to my where my interest in shortwave really began. Christmas 1971. Santa was kind enough to set me up with a cheesy eight-track tape player-AM/FM stereo. But the shoddy Hong Kong technology inside offered me a really surprising gift– stray images of shortwave stations on the AM dial! And the two stations I recall getting quite well on this little woodgrain wonder were Radio Habana Cuba and Radio RSA. I became quite familiar with that chirpy bird and the plucky guitar, and after sending them a letter I was embarrassed for years when a glossy program guide from a faraway racist regime would show up in my mailbox every few months. Then a Christmas or two later I scored a flip-cover multi-band box that introduced me to the wondrous world of cold war shortwave propaganda.

Anyway, after the interval and the ID, it’s non-stop excitement on EWTN– a Catholic with a computer. Sounds like he’s giving a presentation in front of a bunch of well dressed white folks. Anyway, the guy has a laptop, maybe running a PowerPoint presentation or something and it’s all about catechismclass.com, a web site about guess what? Yawn.

6890 – WWRB USA – The Overcomer Ministry

Bro_scare Last week I carried on about old Gene Scott, which was easy because he’s such a rich character. But in truth, there was hardly any Gene Scott to hear in that clip. I should have waited until I had some substantial Scott audio to play before I spent so much time talking about the guy. Same deal here. Brother Stair’s presence on shortwave trumps Scott’s around the clock radio preachin’, and there isn’t much of him on this scan. But if you’re new to shortwave, Brother Stair’s raspy staccato delivery may be the first voice you really become familiar with because he’s ALL over the bands. And he’s ALMOST as interesting as Gene Scott, but hardly as endearing. However, he is still alive.

Since there’s not much of the Brother Stair in this band scan, I’ll wait to say much more until I find a more representative clip. But in the world of radio evangelism, Stair is pretty unique– kind of a combination of Elmer Gantry, Rumpelstiltskin and Jim Jones. Otherwise known as “Brother Scare,” this old goat somehow manages to enslave babes with his wild-eyed shortwave harangues. I knew there must be some more earthly reasons why so many holy shysters spend all that time yammering on shortwave.

The signal’s weak and there’s some phasing going on, but Stair is in the middle of one of his usual unflagging rants. Some important information here about the Antichrist perhaps. Occasionally I find him mildly entertaining, but not this time. His “Overcomer Ministry” rents this international transmitter from WWRB 24/7, but he broadcasts on plenty of others too. Now you know why some people in other countries might think we’re strange. Read more about the sordid details regarding this twisted geezer here and here.

7125 – Voice of Russia

In Russian. Sounds like the news. Nice sounders. Something about Bosnia…

7160 – WRMI Radio Miami International (Radio Republica)

Wrmi Wow, it’s almost unbelievable, another U.S. shortwave station NOT run by Christian crazies. It seems incredible, but I looked around their website and saw absolutely nothing about lambs, blood or that horrible lake of fire. Maybe they’re just coy Christians. Either way, they do allow the Bible people to rent time on their transmitters. There’s just not a long line of normal people out there willing to put up the dough to broadcast on shortwave. So like WBCQ, WRMI needs to take the cash where they can find it.

This particular broadcast is put on by an organization known as “Radio Republica.” They’re for non-violent change in Cuba, human rights, that kind of stuff. As far as I can tell they’re not related to Radio Marti and any propaganda arm of the U.S. government.  But they’re not making Fidel happy either.

Of course, this broadcast is in Spanish. This short clip features a smokey voiced woman who might be talking about a “political prisoner.” They’re signal is often jammed by Cuba, and I’ve read that Radio Republica just started using this frequency.

7180 – Voice of Russia

In Spanish. I believe this is news.

7250 – (Unknown in Spanish)

It’s strange, but this one’s out of order. I might have backed up to find Radio Slovakia after this OR I wrote down the wrong frequency. Nonetheless, it’s VERY clear and most likely originating from North America. Could be Christians doing their dirty work, but I have no idea. If anybody can translate this (or knows of a Spanish broadcast on 7250 at this hour) and can make sense of this reception, I’d appreciate it. There is some urgency in this program.

Slovakia_qsl_2 7230 – Radio Slovakia International

This is a typical English international broadcast from overseas that you might stumble across on shortwave. It’s around ten after the hour and we probably just missed some headlines. And now it’s time for some features on local doings in Slovakia. And at 150 Kilowatts of power from well over 4000 miles away, it’s coming in quite nicely.

Apparently there’s a bunch of illegal weapons stockpiled in closets and attics across the Slovak Republic, and the government’s trying to get people to voluntarily hand them over. Previously loose gun laws have tightened up quite a bit since the end of the cold war. While thousands of Czechs gave up their guns in a similar program, the Slovaks are a bit more wary about letting go of their weaponry so far.

The next story– all about a Slovak high school course on how to prepare a business plan. (And please, when producing radio and the subject of money comes up, don’t even THINK about playing that damn Pink Floyd song again.) Jeez. Enough already.

However, this is still one of the small joys of shortwave radio– hearing small regional stories from thousands of miles away that would never garner coverage in American media.

Egypt_qsl 7270 – Radio Cairo

Spanish talk, female speakers, Middle-Eastern pop bumper music. Plenty of countries beaming Spanish language programming to the Americas. After all, probably a higher percentage of Spanish speakers on this side of the world know how to operate a shortwave radio.

7285 – Hrvatska Radio (Croatia)

Unknown language, broadcast from a relay in Germany.

7300 – Voice of Turkey

As far as music on shortwave radio, this is one of my favorite stops lately. It’s a program of haunting, beautiful and catchy Turkish music. One of these songs has lodged itself in my brain, and it keeps playing there– a comforting exotic loop in the background when I’m lost in thought, and that’s fine with me for now. A couple weeks ago I was haunted by “Saturday In The Park” by Chicago. WHY I ask? What did I do to deserve this?

Votsticker I have an old Zenith Transoceanic in my room, and throbbing modulated music like this from afar played through that warm old tube radio could make you cry. Or, at least it could make me cry. You might laugh. The music plays on in this clip for almost 15 minutes. A female announcer talks between tracks.

That’s it for this week. And as if there’s any enlightenment you can offer– mistakes I’ve made in this post, or translate any of the foreign languages in this band scan– either may assist me in amending or correcting this post in the future. Please post a comment or send me an email here. Other articles in this blog series can be found here.

Thanks for listening.

Adventures In Amplitude Modulation – Part 10

Monday, February 20th, 2006

Bcl2000wbcq As promised, this post is a continuation from last week’s shortwave listening sessions from September 2004. These radio recordings offered here were received on a Tecsun BCL-2000, and the location of reception was a small town on the Hudson River not too far from Albany, New York.

As before, after the jump you’ll find more MP3 samples of shortwave reception to sample, but first I want to talk specifically about the radio that I used to make these recordings. It’s a practical gadget that’s not too expensive.

The BCL-2000 itself can only be purchased in the U.S. via ebay. However, a couple of almost identical radios under the Grundig (or Eton) name are available in North America at a somewhat higher price and are only slightly different . Just to avoid confusion, from here on in I’ll describe these receivers as the BCL series of radios, and point out differences when appropriate.

The BCL series is a recent invention, developed and built in China and first released in 2002 (the American version, the Grundig S350 went on sale in 2003). Just like almost every other new electronic gadget, most shortwave radios are now made in China. While purists loudly bemoan the loss of new European and American receivers in the marketplace, the Chinese are making some damn good radios these days and often at an affordable price. Although the trend in shortwave has been toward digital tuning for years, the BCL radios buck this trend and have proven a popular alternative to the abundance of digital shortwave sets for sale.

While they don’t really have any features that haven’t been seen before, the BCL radios offer a unique combination of options that make it a lotta fun to scan the bands. The main difference between these radios and any other affordable receivers available today is that they offer analog tuning WITH a digital display. And the LED display is also relatively large and there’s a switch to lock the display light in the on position on these radios, which makes it great tool for searching out distant frequencies in the dark.De1103

And some will ask, if the display is digital why not just get a digital radio? Well, when I bought my first digital shortwave receiver a few years ago I quickly began to realize how much I appreciated analog tuning. Going through each 5 KHz step with a digital tuner gets tedious very quickly. And then if you want to zip across the band and get a feel for the reception available, forget it. Each step requires a fraction of a second to be heard, with a “phhht” sound as the radio renders each frequency up, and I believe it adds a bit of background noise as well. The alternative you get is a scan function, which silently automates the scanning process and the turner will stop when the radio’s software decides there might be a broadcast at that frequency. It ain’t the same. And as you might imagine, weak signals can be easily skipped and stray RF can be mistaken for a radio station.

Okay, I know that with better digital tuners some of these problems aren’t as bad, and miserable Sangean ATS-505 isn’t the best example. However, I’d still rather do the scanning very manually sometimes.

Ats505 That’s not to say that digital radios aren’t amazing in other ways. Many have hundreds of presets, and if you know the frequency you’re looking for you can usually punch it up immediately. And for the most part, the best shortwave receivers made have been all-digital for quite a while now. While BCL radios are NOT the very best receivers in any technical sense, they are very easy to use and reasonably priced.

Besides not having presets, the BCL radios also don’t have another feature dedicated listeners desire– SSB. While I’m not going to get into a technical discussion I’m not qualified to offer, I’ll just say that SSB (Single-sideband modulation) is another way of broadcasting other than amplitude modulation which is more efficient in long-distance transmission and is popular with ham operators and some international broadcast services. Some listeners love to eavesdrop on the hams (if you don’t know what "ham" is, look here), and others just like to have all the options.

Tecsun_factory_1_1 The truth is, the BCL radio design borrows a lot of its layout and operation from a popular analog receiver from the 1970′s, the Panasonic RF-2200. While the RF-2200 did not offer a digital display, the template for the radio’s controls is very similar. And both are very good medium and shortwave receivers. Ideally, I would hope that future versions of the BCL radios would incorporate more of what made the RF-2200 great– like SSB, as well as the pop-up rotating antenna for AM, and dual conversion circuitry that would reduce the one other big complaint about the BCL radios, “images” from strong broadcasts popping up on other locations on the band.

The original BCL-2000 was released in China in two colors, black and a bright and cheery red shade. The U.S. version, the Grundig S350 was only offered in a utilitarian gadget silver. The initial release was plagued with “drifting” issues, as the tuning is a string and pulley affair where physics are at play on the variable capacitors and once you’ve settled on a frequency the radio would tend to drift off signal eventually. The Chinese Tecsun versions addressed this issue early on, and that fact combined with the more appealing casing colors made the Chinese version a popular item on ebay in the U.S., despite the fact they aren’t available in the stores here.

What’s interesting is how this radio was marketed in the U.S. BCL stands for “Broadcast Listening,” and that’s what the radio was meant to do, provide easy access to the old broadcast bands. In fact, the Tecsun version says “Enjoy Broadcasting” right on the face. The Grundig however, was called a “field radio” and was promoted for it’s “military” and “retro” look. Which makes you wonder why it didn’t come out in “camouflage” pattern, or at least in army green. Could the military marketing approach had anything to do with the current obsession with warfare and patriotism in the states? Makes you wonder.

Tecsun_factory_2_1 However, things have changed. While the original radios are still for sale, there are new versions available which have addressed the “drifting” problems in a more direct way. In America, the new radio is called the Eton (not Grundig, but it’s just a nameplate anyway) S350DL. Instead of adding all the technical features real radio fans might desire, (SSB, dual conversion) they’ve again gone for a more superficial approach. The radio is slightly bigger, with a larger speaker AND it comes with a set of headphones. And guess what? The S350DLs aren’t silver at all, but are RED or BLACK, just like the Tecsun versions. However, the knobs are silver now, instead of black. Not exactly an improvement.

The new Chinese version is no bigger and has no headphones. It’s called the BCL-3000, and now only comes in black. From everything I’ve read, these radios are no more sensitive than the previous model. There is a technical solution to the drifting problem which I’ve heard is problematic. When you stop on a station, the frequency locks. However, the locking is buggy and can be a pain in the ass when you’re trying to tune something in incremental knob nudges and the tuning locks up or jerks at inopportune moments. I’d rather deal with the slight bit of drifting myself.

While the BCL-3000 is still roughly the same price, around fifty bucks plus shipping from China (roughly 80 some dollars total). The S350DL however, is now $150 dollars, a jump or fifty bucks from the list price for the S350. And just to keep your radio buyin’ eyes off of China, there’s been some arm twisting over at Tecsun headquarters and all newly manufactured BCL-2000 and BCL-3000 radios are no longer labeled in English. They’re covered with Chinese text, and you may need to refer to the translated manual to figure out the knobs and switches. The controls aren’t that complicated, but it is an annoyance for the non-Chinese radio consumer.

IS350dl_2 ’ve not only gone in detail about these radios because I happen to like them, but I also think they are very good entry level DX radios. The AM performance is actually a little better than shortwave and FM reception is very good. But what they do offer the shortwave listener is an intuitive analog interface to the tuning, while providing an accurate digital readout of the frequency in real time, which can be strategic in trying to identify a station in the shortwave jumble of frequencies. No presets, it’s true. But a little knob twisting will get you anywhere you want to go. One other plus– these radios run forever on 4 D cell batteries. The digital portables suck power at a much higher rate.

Okay, on to the audio clips. These stations were received in the evening in upstate New York on the weekend of September 11, 2004. And although I was using my BCL-2000 I did not make notes of the actual frequencies received. I’ve never been one to keep logs, or collect QSL cards. But all my respect to those who do. Suffice to say most of the signals received were probably in the 49, 41 01 – Sweden Todaand 31 meter band. Possibly the 25 meter band as well.

01 – Sweden TodaySweden_2  4:09

It’s Radio Sweden International broadcasting in English for North America at 6010 KHz in the 49 meter band. (Thanks Mr. Announcer) It’s a news magazine program and the lead story is about one of the unexpected side-effects of the European Union– more intoxicated Swedes.

02 – Voice Of Turkey  18:08

(download)

While Radio Sweden notes a unplanned downside to being a part of the European Union, on the Voice Of Turkey broadcast you hear repeated references to how strong the desire is for the Turks to merge their country into the EU. Over and over again in this extended segment you can hear how Turkey has been bending over backwards to satisfy their European’s neighbors that they are worthy of Turkey_logo_2membership in the Union. It’s not only mentioned in every element of this extended clip, but there’s even a regular segment here specifically focusing on the latest news regarding Turkey’s application to join the EU. It is so odd in this era to hear such yearning on  behalf of a Muslim nation to join into such an intimate relationship with western powers.Turkey’s shortwave service runs a strong transmission to North America, and I’ve heard some great music there more than once. The reception on this recording requires a little patience, but it’s all there. And it’s traveling over 5000 miles.

03 – Deutsche Welle-Inside Europe  25:06

(download)

Deutschewelle1 More on EU issues in this clip as well. Not the kind of news you’re likely to hear much about in American media. Deutsche Welle offers an excellent English service, and sadly they recently made the same decision as the BBC World Service made a few years ago– to dramatically curtail their broadcasts to North America. The statistics of U.S. shortwave radio listenership aren’t exactly a motivating influence for international broadcasters. And cutbacks in funding toward broadcasting to North America from overseas has made the Christian-crazy packed U.S. shortwave scene a little less interesting lately. It’s a goddamn shame.

The big story here is about halfway into this file. While Turkey is jumping through flaming hoops to entice the EU to let them in, while the Prime Minister, a devout Muslim, was trying to pass a law at the time making adultery a crime. See the conflict? If you just heard the Turkish broadcast before this you might guess what happened next. There’s a couple small drifting/tuning issues in this recording. The off-frequency moments are brief. The reception is fair.

 04 – Catholics & Protestants  2:20

(download)

Ewtn_sisterMost of the Christian prescience on shortwave is decidedly Protestant. A lot of King James Version faithful who offer you the choice between the fluffy clouds of heaven and the fiery pits of hell. However, EWTN’s Global Catholic Network is a little more chatty than their Protestant counterparts. Instead of preaching, they talk about stuff on EWTN. On this clip you hear the spiritual wisdom of “Dan.” He sounds like he’s at least 17 years-old. And then two more Protestant type stations. A hymn and little pulpit thunder.

05 – Parking Lot Miracle – Ukraine Signs Off  4:33

(download)

Jesus_cracks_up Here’s little slice of band-scanning, going through some Jesus-casters and ending up overseas. It starts off with a mind-blowing miracle involving God expanding a church parking lot just in the nick of time. Also some gospel passion and World Harvest Radio’s offer to ship you a free Bible so you can play along at home.

And then there’s Radio Ukraine International signing off at the end of their broadcast to North America. While I can’t speak authoritatively about Ukraine’s English shortwave service, I always love hearing it. There’s something home-baked about it, lots of Ukrainian culture, history and music, and it sounds like radio from decades ago. For some reason, it’s like radio comfort food for me, and hearing it on the internet just wouldn’t be the same.

06 – (Unknown Station) Christian Election Advice  2:28

(download)

Bush_kerry_2 This saddened me at the time. It’s some type of Christian talk show, slightly paranoid in the shortwave tradition. Talking about the upcoming Presidential election, one co-host remarks to the other that voting for the “lesser of two evils” is wrong for Christians.  And while I could have been pleased with concept of Christians boycotting an election en masse, the idea of telling people not to vote because each candidate is imperfect just plays into the hands of political smear tactics in general. Like so many ideas brought up every day on Christian radio it’s the product of immature thinking and lacks moral clarity.

 07 – WBCQ-More Timtron  14:28

 (download)

Last week I featured a bit of Radio Timtron Worldwide, arguably one of the best shows on shortwave radio, broadcast on WBCQ in Maine. This is part of another show (The Real Amateur Radio Show/Piss & Moan ) he hosts which is always some discussion of his life in radio, and a few tips and tricks for listeners as well. And it’s like nothing you’ll hear anywhere else.

Another show on WBCQ that offers colloquial details on the outlaw-fringe side of radio broadcasting is “Allan Weiner Worldwide,” hosted by WBCQ founder Allan Weiner. Allan’s program is an informal “around the house” kind of talk show, with Allan talking about the station, the state of radio, or whatever’s going on in his life. And he does take calls, but it sounds like it’s really just a small group of chronic middle-aged geeks who haunt the phones. But when you listen to these shows you become privy to the realities of seat-of-the-pants broadcasting that is both  infectious and inspiring. They both have GREAT stories of both their pirate radio days as well as anecdotes about the everyday goings on with maintaining WBCQ. Just the offbeat techno-slang and vernacular they use when they talk about their years of pirate radio shenanigans, or relate the behind the scenes details of maintaining a bunch of high-power transmitters. Just listening makes you feel like your part of things up there in Maine, and in the process you learn a few things about the business and science of radio.

And that’s what you get here with Timtron, technical talk with attitude and a bent sense of humor. Maybe only on shortwave would the esoteric musings of radio engineer be so appropriate and so entertaining. He makes advanced radio engineering sound as easy as putting together a high school science project. Just another reason to check out WBCQ. By the way, online archives of WBCQ programs can be found here.

 Thanks for listening.
