BBC Local: Mediumwave Closures in 2018

(Source: BBC)

We are closing a number of BBC Local Radio’s medium wave transmitters in January 2018. This will not affect listeners who use FM, digital radio, digital TV, or the internet to listen.

Why is the BBC switching off these transmitters?

We know how much our listeners value BBC local radio – and have invested significantly in this area through our commitment to funding Local DAB expansion and adding all English Local Radio services to Freeview. The savings from these closures will allow the BBC to continue to modernise its infrastructure in order to meet our listeners’ changing needs.

Why have these particular transmitters been chosen?

We assessed the coverage of each BBC Local Radio station on FM, MW and digital radio which highlighted stations where medium wave transmitters duplicated good FM or digital radio coverage. Following this process, we trialled the switch off of a number of medium wave transmitters and asked for audience feedback.

Taken together, the audience feedback and the coverage data have informed which medium wave transmitters are unlikely to be value for money in the longer term.

More information on why we are doing this can be found on the BBC blog.

Listeners can also use the interactive transmitter tool to see how they can receive their local radio service on other radio and television platforms or use iPlayer Radio to access their local radio service.

Guest Post: Late Night Pre-Christmas Mediumwave Scan, NYC 2017

Many thanks to SWLing Post contributor, The Professor, who shares the following guest post:


Late Night Pre-Christmas Medium Wave Scan, NYC 2017

I haven’t recorded a proper scan of the AM dial in New York City for a while, so I took a shot at it a week before Christmas, starting around three A.M. Monday morning, December 18.

I asked Thomas if his readers might be interested in the audio from an AM scan here and some annotations, kind of like I used to do on my Radio Kitchen blog not so long ago. When I scan the dial I often start at the top of the AM dial and work my way up, but sometime it’s fun to do it the other way around and begin with more low power small stations where the fare is a little more exotic than the typical talk and news formats you hear from regional and powerful clear channel transmitters up the dial.

I have a number of radios that would really be better candidates to do this sort of thing, but since I’m kind of between places right now and most of my radios are in a storage unit somewhere, I’m using the Tecsun PL-880 I have with me. And typically I’d do this with a loop antenna up next to the radio, but they’re in storage too. So it’s just the stock ferrite antenna inside the radio doing all the work here. There’s some of the typical urban RF noise in the mix, but it’s not all that bad. Then there’s the awful splatter of digital IBOC to plow through. Not fun to listen to, and some stations you might otherwise find are masked by hash.

If you don’t listen to AM this late at night (or this early in the morning), it’s really not a great time to hear live programming. A lot of talk shows from daylight hours are rerun at this time, and the few music stations you might find are often running music automation with no live DJs. But a few talk local talk shows in big cities are live, and syndicated ones like Coast to Coast or Red Eye Radio are broadcast live overnight on quite a number of stations.

Instead of trying to do a lot of DX digging and pull in the really hard to hear stuff, I’m not equipped for that right now so I just plow through looking for what I can find without too much trouble. As I said, I didn’t have another antenna to assist me, but I duly rotated the radio and adjusted the bandwidth when appropriate. If you’re keeping score at home I do at least pause on every viable MW frequency, even if there’s nothing there.

I wouldn’t say it’s a typical late night New York medium overview of the band, as a few common finds on the dial were missing, and didn’t find many of the smaller Canadian locals I’ve heard on other nights. The one difference is that for years I’ve been listening from my former home in Greenpoint, Brooklyn. For now I’m down in Bay Ridge, at the bottom southwest corner of Brooklyn, and a few things are different. Like the very first station I come across.

Click here to listen to or download Part 1 (MP3).

1710 kHz – This scan begins with an oddity, WQFG689 a “traveler’s information station” broadcasting just a notch above the x-band, but a spot on the dial that is still included on contemporary AM radios. According to Wikipedia it’s the only legit station in America broadcasting on 1710. It’s owned by Hudson County in New Jersey broadcasting on a handful of ten watt transmitters. I’m assuming this reception might be coming from Jersey City, which is across the water not far from here. A few years ago one of the Hasidic communities in Brooklyn had a lo-fi pirate station at this frequency, but I haven’t heard it there in a long time. And as WQFG689 sits in a very lonely place on the dial, this station is a popular DX target. Apparently at this hour they were experiencing “technical difficulties.”

1690 kHz – Some contemporary R&B style pop song with a male singer. It’s an English language performance however (is it Spanish?). I’m not sure what this might be, but from looking around on the web it may be CHTO, a multicultural station in Toronto, Ontario.

1650 kHz – A weak reception of a talk radio show. Some discussion of the desires of Harvey Weinstein and other matters. Perhaps this is WHKT in Portsmouth, Virginia.

1630 kHz – At this spot on the dial I receive an image of WINS (1010kHz) as well as some station broadcasting the unavoidable Brother Stair. Don’t know exactly what is going on there, but the PL-880 is known to toss in some stray images on the dial in dense radio markets like New York.

1600 kHz – Some spirted South Asian pop music. Bollywood stuff I suppose. This would be WWRL here in New York, broadcasting from Secaucus, New Jersey.

1570 kHz – I believe this is the Eagles singing about Christmas. I have no idea what station this might be. WFLR in Dundee, New York is a guess.

1560 kHz – A little bit of Bible from Family Radio – still on New York City radio, but not on the FM dial anymore. Otherwise known as WFME here in New York. Armed with fifty-thousand watts, their signal has quite a reach. I hear the ghost of Harold Camping on here from time to time.

1530 kHz – Speaking of ghosts, it’s Ol’ Brother Stair buying some time on WJDM in Elizabeth, New Jersey I believe. Is he in prison yet?

1520 kHz – Sports talk from WWKB in Buffalo, New York.

1500 kHz – A discussion of Christmas treats on WTOP in Washington, D.C.

1480 kHz – Seasonal mischief in Chinese from WZRC, a Cantonese station here in New York.

1460 kHz – Some distant choral or Christmas music from somewhere.

1430 kHz – Casual talk of God’s happiness plan from WNSW in Newark, New Jersey. Not to judge, but Catholic talk radio is just more civilized than most Protestant talk radio. A little more breezy than the fire and brimstone stuff. They always sound like their shirts are ironed. Carrying the Catholic radio network “Relevant Radio” is the latest format at this frequency in the city. Before that the “Voice of Russia” was broadcast here.

1380 kHz – More Chinese talk. This time it’s from another multicultural station – WKDM here in New York City.

1350 kHz – A poor reception of late night talk. I believe it’s “Red Eye Radio.” I really don’t know where this is coming from.

1310 kHz – A female host on a talk radio program. Mediocre reception from another unknown AM station.

1300 kHz – Again, a female conversation here as well, but this time the topic is spectator sports of some kind. I’m thinking this is the ESPN affiliate WAVZ in New Haven, Connecticut.

1280 kHz – A medical case study in Spanish and English from WADO, here in New York. This is a Spanish news/talk station owned by Univision.

1250 kHz – It’s WMTR in Morristown, New Jersey, which is essentially the only true oldies station that reaches New York City. During the day it’s not a rock solid signal in New York, but anybody who knows how to fiddle with a decent AM radio can pick it up. At night, I had a hard time getting a good read on WMTR when I lived up at the top of Brooklyn, but down here in Bay Ridge at the South Brooklyn waterfront it’s pretty solid as you can hear. Starting with “Da Doo Ron Ron” and “Sugar, Sugar” I let it roll for a few minutes. Not many radio stations play a “classic oldies” format these days, or if they do it might just be the torture of a super tight 300 song playlist. While WMTR can’t top the huge music library of WLNG out at the end of Long Island, they rotate a respectable mix of the old hits. There’s a rather interesting Wikipedia entry for WMTR, where you can read about their experimentations with AM Stereo and how they’ve tweaked their oldies rotation over the last few years, partly in response to WCBS-FM in New York moving away from oldies into a morass of format noodling.

1210 kHz – WHPT in Philadelphia playing the conspiracy/paranormal Coast to Coast program, the most popular syndicated overnight radio show in North America. It’s George Knapp hosting, but during the week it’s George Noory. The original host and creator of the program, Art Bell is long gone after quitting radio about five times. After one A.M. or so, moving across the AM dial means you’ll come across Coast to Coast many times. Tonight the topic is Area 51, which is hardly surprising.

1190 kHz – Some contemporary R&B flavored Christian music from WLIB. in New York. This station was actually the original flagship station for “Air America,” the short-lived progressive talk network. For those of you who may remember WOWO, the Midwest clear channel 50,000 watt station heard far and wide at 1190 from Fort Wayne, WLIB’s powerful 30,000 watt upgrade is directly related to that Indiana station’s demise as a nighttime powerhouse. Back in 1994 the owners of WLIB actually bought WOWO for the specific purpose of cutting back their signal after dark (It’s now only 9,300 watts and directional) so WLIB’s could be increased up to what it is today. Sneaky, eh?

1180 kHz – Coast to Coast again, this time coming from in WHAM, in Rochester, New York. Great call letters.

1170 kHz – Coast to Coast coming from WRVA in Wheeling, West Virginia this time.

1130 kHz – WBBR in New York, otherwise known as “Bloomberg Radio.” I may find it kinda tedious, but if you’re a big time profiteer this might be your favorite radio station. Just listen to the commercials, sheesh! And as a bonus you get a public service announcement about how high-tone Manhattanites should prepare for disaster.

1110 kHz – A strong read of Coast to Coast from WBT in Charlotte, North Carolina.

1100 kHz – It’s WTAM in Cleveland, Ohio broadcasting Coast to Coast. Not as strong as the signal from Ohio.

1090 kHz – WBAL in Baltimore, Maryland offering some tips on “layering” customer rewards programs.

1050 kHz – Sports in Spanish from WEPN in New York City.

1030 kHz – WBZ in Boston, Massachusetts. Something about hips. One of the few talk stations I’ve heard which still specialize in local programming around the clock. WLW in Cincinnati would be another.

1010 kHz – WINS in New York. News radio which still features the hokey teletype sound effects in the background. I let this play for a few minutes, including a PSA about a cocaine cessation program.

960 kHz – Something about a meatball sub. It may well be WELI in New Haven, Connecticut.

970 kHz – 970 “The Answer,” otherwise known as WNYM in Hackensack, New Jersey with top of the hour Fox News. The big story – the power outage at the airport in Atlanta.

Click here to listen to or download Part 2 (MP3).

970 kHz – More Fox News from WNYM in New York City.

950 kHz – Choral Christmas music. Probably the Family Radio outlet WKDN in Philadelphia, Pennsylvania.

930 kHz – WPAT, a brokered station in Patterson, New Jersey. In this late night slot it’s either an infomercial or just a discussion of meditation and mindfulness.

920 kHz – Newsradio 920, an iHeartMedia station – WHJJ in Providence, Rhode Island. The weather.

910 kHz – “Eight Days a Week” from the Beatles. I don’t know where this is coming from, but it might be bumper music for a talk radio show like Coast to Coast (They often let the bumper music play for a minute or two) or a full playing of the song on a music radio station. Some crosstalk from a talk station in the mix on this reception.

900 kHz – CHML in Hamilton, Ontario. I know this Canadian news and talk station for playing old time radio shows overnight. Kind of odd to me that they’re covering the hearings of an American judge. Followed by some news about Prince Harry.

880 kHz – It’s WCBS in New York, a powerful clear channel news outlet heard across the country. Here you get a dramatic report on four separate shootings in New York City, the kind of news you don’t hear so much these days. I let this play for a few minutes.

860 kHz – Very poor reception of CJBC, a French CBC outlet in Toronto. I’ve heard a wide variety of great music on this station over the years. I almost always would get a good copy on this station from my former home in North Brooklyn, but then again late night AM reception does vary.

820 kHz – WNYC-AM in New York, the sole NPR outlet on the AM dial in the city. Overnight they carry the BBC World Service, which is what you hear in this scan.

770 kHz – Trump apologetics from “Red Eye Radio” on WABC in New York. While this syndicated program has roots in Bill Mack’s great country music program, now it’s just one more conservative talk show. But it’s the exception to the rule as most live overnight talk radio programs don’t stray into political opinion like this, unlike during the day when it’s everywhere.

750 kHz – WSB in Atlanta, Georgia. It’s a strong signal up the east coast. Here I find them in a commercial break which leads into a snippet of a rebroadcast of the Johnny Kielbasa Final Fast Food Review of 2017. Then the much beloved Meg calls in.

740 kHz – CFZM, or “Zoomer Radio” in Toronto, Ontario. It’s a quirky format, and often the only dependable music radio station for listeners in the eastern middle of North America. Here we’re treated to Jim Croce and some holiday fare.

710 kHz – WOR in New York. It’s former WABC talk host Mark Simone enthusiastically selling “My Pillow.” AM radio can be so comforting late at night, but the IBOC surrounding this frequency not so much.

700 kHz – You can almost hear WLW in Cincinnati, Ohio trying to cut through the IBOC from WOR, but it’s a mess. I guess it’s a sacrifice so all those dozens of HD radio listeners can enjoy WOR in all its digital glory.

660 kHz – WFAN in New York. Sports radio heaven I guess.

640 kHz – Some old-fashioned vocal belting in Spanish. Not sure what this is. Perhaps WWJZ in Mount Holly, New Jersey.

620 kHz – WSNR in Jersey City booming in. Here you get one of the epic and much-played recordings of Alexander Scourby reading from the King James Version. What a voice – warm, authoritative and dramatic. I have to admit he sounds dated, but in a good way. His recitation of the Bible is still popular almost seventy years after it was recorded.

610 kHz – Difficult to read signal of a talk radio show. Male host. I’m guessing this is sports talk WTEL in Philadelphia.

600 kHz – Another hard to hear transmission of a talk show with a male host, and it seems to be another sports discussion.

570 kHz – A cheesy Infomercial on WMCA. Once a great top 40 station, WMCA was also where the “Father of Talk Radio” Barry Gray got his start back in the nineteen-forties. Nowadays it’s a New York City Christian outlet owned by Salem Media, which apparently pays some bills by playing tightly edited testimonials praising the miracles of consuming fruit and vegetable pills. I never hear programming like this promoting a diet of real fruits and vegetables.

560 kHz – More Christian broadcasting from another former legendary top 40 station, WFIL in Philadelphia. They’re also owned by Salem. Some more traditional preaching, and not a great signal arriving here in Brooklyn.

From there, I stop by a couple very weak signals up to the top of the dial, and that’s it.

There were a number of radio stations I almost always hear late at nights that were absent or very faint in this scan, like WHAS in Louisville, WAY in Schenectady, WJR in Detroit and WHKW in Cleveland come to mind. And on a good night (especially if the IBOC on an adjacent station isn’t active), if I can null out a booming local next door I can receive WSM in Nashville, or KMOX in St. Louis and even occasionally pick up WLS in Chicago sneaking over the edge of booming clear channel WCBS at 880.

I hope some shortwave listeners find something of interest in this medium wave excursion. Thomas runs a fantastic blog, and I’m proud to be a little part of it today.

Thanks for listening, and reading.


Thanks so much, Prof, for taking us on a guided tour of the Brooklyn AM radioscape!

I thoroughly enjoyed your recordings and, especially, your commentary and insight.  You’re welcome here on the SWLing Post anytime.  I’m also posting your recordings and notes to the Shortwave Radio Audio Archive.

WRTH 2018: A look inside

I received my copy of the 2018 World Radio and TV Handbook (WRTH) directly from the publisher yesterday, just prior to my Christmas holiday travels. As I mention every year, I look forward to receiving this excellent staple radio reference guide–and this is their 72nd edition!

WRTH’s team of noted DXers from around the world curate frequencies and broadcaster information by region; while I’m not sure how they orchestrate all of this, the end result is truly a symphony of radio information. In addition to broadcaster listings, WRTH’s radio reviews, feature articles, and annual HF report make for excellent reading.

But the WRTH isn’t just a frequency guide: the publication always devotes the first sixty or so pages to articles relating to various aspects of the radio hobby. Following, I offer a quick overview of these.

WRTH broadcast listings are incredibly thorough and informative

The first article always features a WRTH contributor:  this year, they feature Torgeir Woxen who is the contributor for Norway and editor of the Asia & Pacific frequency list. Reading about how Woxen became interested in radio and DXing reminds me of how I–and many of my radio friends–got their start as well.

The second set of articles is always my favorite: WRTH receiver reviews.

This year, WRTH begins with a review of the Icom IC-R8600 wideband tabletop SDR receiver.  They also review the Tecsun PL-880, Tecsun S-8800, Expert Electronics ColibriNano, SDRplay RSP2, and the new AOR AR-DV10 wideband handheld

Besides radio reviews, WRTH also includes an evaluation of the Cross Country Wireless Active Loop.

I must admit: the Cross Country sounds like an effective and affordable portable mag loop antenna. I might need to grab one in the future to use on impromptu travels and DXpeditions.

The following article features WRTH contributor, Brian Clark, and his travels from New Zealand to the geographic antipodes of his home: Spain, Portugal and Morocco. Of course, enjoying diverse radio broadcasts was an integral part of his journey!

I was pleased to find that the following feature article, entitled Receiving Noise, explores the radio interference that plagues our hobby. The article mentions several common sources of noise and some of the antennas that most effectively mitigate RFI. Sadly, radio noise/interference is an important topic for most radio enthusiasts.

Following this, WRTH writer, Hans Johnson, features an article on Radio Romania International. RRI is one of my favorite shortwave broadcasters, so this was a treat to find indeed–Johnson’s piece sheds light on the past, present and future of the station.

Next, in A New Voice of Hope in the Middle East, Founder and President of the Strategic Communications Group, John Taylor, writes about setting up a new mediumwave station in Israel.

The following article features Dr. Martin Hadlaw, a former advisor to the Solomon Islands Broadcasting Corporation (SIBC), who explores the history of broadcasting in the South Seas.

Next, WRTH feature their Digital Update which assesses the state of digital broadcasting and–this year a special note about–Digital Radio Mondiale.

The final article–a tradition–is the WRTH  HF propagation report/forecast by Ulf-Peter Hoppe. Always an informative read and this year he ends on a positive note despite the fact we’ve hit the solar rock-bottom!

The 72nd is another fantastic edition of the World Radio TV Handbook. As I say every year, I’ve never been disappointed with WRTH. Their publishing standards are such that the quality of their reviews, their writing, and (most importantly) their broadcast listings are simply unparalleled.

My WRTH 2018 and Digitech AR-1780 fit perfectly in my Red Oxx Lil Roy and are ready for holiday road travel and radio fun!

For DXers who collect QSL cards, you’ll find that broadcaster contact information in WRTH is often more up-to-date than a broadcaster’s own website. When readers contact me asking for QSL information from an obscure broadcaster, the first place I search is the current WRTH. Remember: their information is based on volunteer contributors who specialize in specific regions of the world–the most knowledgeable regional DXers keep this publication accurate.

Purchase your copy of WRTH 2018 directly from WRTH’s publishers, or from a distributor like Universal Radio (US) and Amazon.com (US), Radio HF (Canada), or BookDepository.com (International).

Don shares spectrum recordings from northern Peru

Many thanks to SWLing Post contributor, Don Moore, who writes:

I’ve been traveling through northern Peru and I’ve made some SDR recordings along the way – medium wave, long wave, and some shortwave meter bands. I hope to eventually get through them all!

I have also uploaded some recordings to a shared Google drive so that other DXers can hear what the bands sound like in northeastern Peru, on the edge of the Amazon jungle. Maybe some of the blog readers would be interested in this. You will need the below link to see the SDR files and an explanatory document. I plan to add a few more once I get another hotel with a good Internet connection again.

Click here to download.

Fantastic, Don!  Thank you for sharing your spectrum recordings!

Post readers: If you don’t already have HDSDR installed on your PC, you’ll need to grab it here. HDSDR is free and can playback these spectrum recordings. Once installed, simply press the “play” button on the HDSDR console and point HDSDR to the downloaded spectrum file. You’ll be tuning through Peruvian spectrum in no time!

How to find North American stations broadcasting in C-QUAM AM Stereo

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

Just how many MW stations in North America are broadcasting in “C-QUAM AM Stereo” these days?? I found this reference which appears to be the most accurate list around the internet.

http://www.meduci.com/stations.html

I have taken this list and have edited it and converted to a PDF file [click here to download].

Best way to catch a AM Stereo signal these days is with a SDR device. We have been using Bernd Reiser’s “SoDiRa” program (version 0.100 Preview 24) with a SDRPlay RSP1 and does an excellent job with C-QUAM AM Stereo decoding.

http://www.dsp4swls.de/sodira/sodiraeng.html

During sky wave nighttime conditions we received CFCO in Chatham Ontario well of late on 630 kHz in AM STEREO (country music format). Program also appears to have built in DRM and DRM+ decoding (we have not tested this part of the program). IMPORTANT NOTE : We found we needed to use the older EXTIO version 3.7 otherwise we encountered errors with OUR connected Windows 7 PC’s (your situation may vary).

Dan Robinson’s JRC NRD-545

Not to forget that the JRC NRD-545 receiver has “built in” AM Stereo decoding (AMS mode). One MUST use the phono jack “line outputs” on the rear panel connected to an external amplifier etc. It does NOT output via it’s headphone connector. Speaking of the JRC NRD-545, please see my web page for late important service information on my “Radio News” webpage.

http://webpages.charter.net/n9ewo2/news.html

Thanks for the tip, Dave!

The last time I listened to a C-QUAM AM stereo station it was with WNNC station owner/manager, Dave Lingafelt. We sat in his beautiful red Buick Reatta, parked at the station and transmitter site and listened to 1970s rock on 1230 kHz.  Needless to say, it sounded absolutely amazing! Indeed, all of Dave Lingafelt’s stations (WNNC, WAIZ and WXRC) sound amazing.

To listen to an AM station in stereo is a real treat. Thanks for reminding us, Dave!

Radio New Zealand plans to exit AM radio

(Source: Stuff.co.nz via Trevor R)

[…]In the longer term, the report raised RNZ’s wish to divest from broadcasting infrastructure.

“RNZ currently owns a significant property portfolio and other related equipment required to support its AM radio services,” it said. “While the AM audience is declining, the cost of maintenance and upkeep of the property, buildings and AM equipment is increasing.”

The report went on to say RNZ was sitting on potentially lucrative land, that could be used for housing.

“RNZ considers it is now time to work with stakeholders to develop plans to, either partially or completely, exit AM broadcasting over time,” the report said.

Thompson said RNZ’s plan to sell of its transition sites would likely take more than a decade. It had just invested in a new AM tower in Titahi Bay, Wellington, that he said cost “millions”.

Through its network of transmission towers, RNZ was also responsible for broadcasting other radio stations including Newstalk ZB and iwi radio stations.

“We think we’re an audience and content organisation, not an infrastructure organisation,” Thompson said.

If RNZ was to sell or close its AM towers, he said the Government would need to make the call. The other broadcasters would also need to be consulted.
