Brilliant! World Radio Map dot com

Our reception locations are worldwide.

Why don't we savor 'simple listening' on the sidelines of travel?


In my opinion, in many cases, maps and atlases are key tools to facilitate intellectual curiosity.

The 'World Radio Map.com' is a website that lists MW/FM/DAB/DAB+ radio stations by their real broadcasting frequencies and enables you to tune in directly from your browser, with no download required.

 An ideal web site for local radio listeners heard worldwide! 

It's also a place to find information about main transmitters and towers' technical data and many radio-related links. 


It covers all the major cities of the world, from Chicago to Acapulco, from Frankfurt to Johannesburg, from Moscow to Tel Aviv, from Shanghai to Melbourne ... can listen online all radio stations from these cities and thousands more from all over the World for free! 

It’s owned and operated by Mikhail Shcherbak (a.k.a. Predavatel) with help of many his friends, including me, around the world.

It's really great job!


Unfortunately, no information of international SW services is available.

Do you think SW broadcasts are important in the 21th century?

We’re not interested in SW broadcasts (I think it might be obsolete!) and I don't own any SDR (Software Defined Receiver) nor communication receiver nor heavy external antenna.

A happy new year 2018!

New Year is the most important holiday in Japanese culture.

Years are traditionally viewed as completely separate, with each new year providing a fresh start.

Consequently, all duties are supported to be completed by the end of the year, whole ‘Bonenkai’ are held with the purpose of leaving the old year's worries and troubles behind.


January 1 is a very auspicious day, best started by viewing the new year's first sunrise, and traditionally believed to be representative for the whole year that has just commenced.

Therefore, the day is supposed be full of joy and free of stress and anger, while everything should be clean and no work should be done.

I'm now in South Korea, since Dec 30 with my family, and
not so much time to listen. coldsweats01

Happy holidays!

Happy holidays!

I've received several greeting cards from international friends.

Many thanks and wish your good luck and happiness!


In my opinion, Christmas has only been widely celebrated in Japan for the last few decades, but is still not seen as a religious holiday or celebration as there aren't many Christians.

Now several customs that came to here from the US such as sending and receiving Christmas Cards and Presents are popular.

Christmas eve is often celebrated more than Christmas Day, thought of as a romantic day, in which couples spend together and exchange presents.

Young couples like to go for walks to look at the Christmas lights and have a romantic meal in a restaurant - booking a table on Christmas Eve can be difficult as it's so popular!

In many ways, it resembles Valentine's Day celebrations in the UK and the US.


The Japanese New Year (called 'o shogatsu') is more like a traditional Western Christmas. New year is the period where families get together, have a special meal, pray and send greetings cards.

New year is celebrated over six days from December 30st to January 3th and is a very busy time.


I make it a practice of traveling at this time of the year as the year-end and New Year holidays.

Over 50 million DAB receivers, now sold Worldwide! 【Viva digital radio】

As you may know, Norway is now the first country in the world to initiate the digital switchover from FM radio broadcasting to DAB+.

National FM networks will be phased out gradually throughout 2017, region by region, starting with Nordland and ending with the Troms and Finnmark regions, which will complete the process in December.

It's really trend of the times, and widely being reported in Japan.


DAB/DAB+ is being operated in several regions worldwide, either in the form of full commercial services, or as feasibility studies.

There is a growing user base in countries as Denmark, Germany, Belgium, and Switzerland.

Also available in APAC countries!

I'm not interested in SW broadcasts and inter-continental MW-DX (I think it might be obsolete), so don't own any SDR (Software Defined Receiver) nor communication receiver nor heavy external antenna!

They might be out of style, but I own a XDR-P1DBP by Sony-EU (DAB/DAB+/FM receiver).

According to my favorite web site ‘Asia Radio Today’, World DAB has published the latest version of its infographic, featuring DAB receiver sales, coverage and household penetration for markets in Europe and Asia Pacific up to the end of 2016.

(The Asia Radio Today)


(The World DAB)



Key findings include:

1. Over 53 million receivers (including automotive linefit) have been sold worldwide

2. Growth in digital radio being fitted as standard in new cars – Norway (98% of new cars with DAB), UK(87%) and Switzerland (66%) lead the way

3. DAB population coverage continues to grow:

Norway (99.7%), Switzerland (99.5%), Denmark (98%), The UK (97%), Germany (96%) and The Netherlands (95%)

4. Next wave of markets developing strongly – 23 countries with DAB services featured in infographic Norway's digital switchover has had a significant impact on digital radio sales and reach, with cumulative receiver sales reaching 3.9 million and listening reach up to 69% at the end of Q4 2016. This is alongside a jump from 63% to 98% for new cars sold with DAB+.


Switzerland, starting its own DSO in 2020, has seen cumulative receiver sales increase to 2.8 million with the DSO marketing campaign due to start this year.

The UK now boasts total receiver sales of 31.7 million, along with an increase in the number of new cars fitted with DAB as standard to 87%.


Over 8 million receivers have now been sold in Germany, with coverage up to 96% of the population and 98% of 'first level' roads. 581,000 receivers have now been sold in The

Netherlands and Italy has almost reached the 1 million receivers sold mark. Over 3 million receivers have now been sold in Australia.

As I posted, the new services are available in Canberra, Darwin and Hobart due in 2017.


"In the last year, digital radio has continued to go from strength to strength and the increase in receiver sales and listeners shows that the future of radio is digital," said Patrick Hannon, President, World-DAB.

‘’It's not just the markets looking at digital switchover, but the next 'wave' where growth has been impressive. In particular, Australia, France, Italy, Germany and The Netherlands have all seen a significant jump in receiver sales.’’

The infographic also details emerging DAB markets for the first time.


In Belgium, it's expected that later this year regular DAB+ services will cover 99% of the population.

In France, regular DAB+ services are due to launch in Lille, Lyon and Strasbourg later this year and Slovenia launched regular DAB+ services in September.

Austrian regulator RTR recently announced it is providing up to four million euros for the launch of DAB+ services.

Denmark would be the next to begin FM shutdown 【Viva Digital Radio!】

Viva digital Radios!

It seems that a really excited event will be occurd in Denmark, next to Norway.

It looks plausible that the next country to shut down its FM transmitters will be Denmark.


The Danish government previously agreed that when the digital radio share reaches 50%, the FM band will be “sunsetted” within two years and over-the-air radio will mainly take place via DAB+, according to 'radio.nl'.

Denmark’s Liberal Alliance political party has indicated that if the rise continues to be in line, the magic number of 50% will be reached by 2018.

Digital radio share is growing steadily in Denmark. In the first quarter of this year, digital listening had a share of 33%. Two years ago, it was 21%, and so the FM shutdown is getting closer, reports the Jyllands-Posten, a Danish daily newspaper.

In October of this year, all digital transmission will be done via DAB+.

‘Slots’ in the DAB+ networks are going to be re-assigned, as well, according to the same article.


For example, the Danish public Broadcaster DR will have three allotments, allowing for the reception of the correct edition of its P4 program in all regions of the country.

Also, the national DAB+ network operator Teracom will begin carrying the commercial radio stations Nova FM, Pop FM and Radio 100.

The remaining channel space may be rented by Teracom to other radio stations.

‘Across the pond’ -2

by Karl Zuk


Is AM, FM and HD Radio enough?

No! There are many more audio sources! SiriusXM satellite radio is also available throughout North America by subscription.

It is quite similar to WorldSpace and the Japanese MobaHo! services now both deceased. North America once had competing systems, XM Radio and Sirius Satellite Radio.

Due to financial instability, the companies merged in 2008 to form a single monopoly.

Over 100 channels are broadcast on SiriusXM, but the content choices are limited.

Many channels are dedicated to sports play-by-play broadcasts and sports commentary.


Talk show channels are also found in multiplicity.

SiriusXM music mixes are reminiscent of an Apple iPod on random shuffle.

How I long for the sounds I listened to in decades gone by when musically trained DJs played excellent mixes adding their commentary to a limitless playlist!

You can count the classical and jazz offerings on one hand.

SiriusXM's best qualities are found in its distribution.

You can pick up their signals virtually everywhere.


The XM system uses geosynchronous satellites hovering about 42,000 km up in stable positions following the rotation of the Earth.

Sirius relies on several constantly moving LEO(Low Earth Orbit) satellites flying in continuous patterns 2,000 km over their service area.

The Sirius LEOs actually provide a superior robust transmission system more apt to fill in hard to reach gaps in coverage.

Additional land-based repeaters, for both XM and Sirius, bring satellite radio content into areas filled with sky blocking business buildings, bridges and tunnels.

If you travel to remote areas, few analog AM and FM radio stations may be heard but SiriusXM shines through.

It may be a Godsend if you have nothing else!




Let's enjoy the year 2017: Internet radio has changed radio forever.

My reliance on portable radios and analog car reception is now a memory.

At home, I can listen in perfect full quality to my computer or smartphone.

My 2016 model car includes Internet radio access.

Imagine rolling along listening to Radio New Zealand International or 4BC Brisbane, Australia in stereo while commuting in the New York City area.

Shortwave listening was never this good!

My mobile listening is made possible by apps loaded into my car's audio system using my smartphone as an Internet portal.


In turn, my smartphone connects to the car's user interface (Toyota Entune) via Bluetooth. My audio choices are wide and varied: AM Radio, FM Radio, XM Radio, iPod, Bluetooth, iHeart, Slacker and Pandora.

Most useful are the offerings provided by iHeart Radio.

You can enjoy select stations from North America and beyond along with custom iHeart music channels very similar to SiriusXM.

You can even customize music to your liking into your own 'channel.'


Pandora and Slacker can also be accessed as alternative music sources.

Pandora allows you to build channels based upon a single artist (i.e Amy MacDonald Radio) to ones based upon genres (i.e. Celtic Folk Radio.)

The choices are limited only by your imagination!

Services not available via iHeart can be heard using the TuneIn or Radio.com apps loaded directly onto my phone.


TuneIn offers nearly every station you can think of, from Paris to Mongolia to Sydney except for all the stations owned by iHeart.

Radio.com provides stations exclusively owned and operated by the American CBS station group. Using these three apps should cover just about all there is!

Now I can listen to BBC Radio Scotland or RTE Radio One during my commutes.

Kaye Adams is my new best friend!

When traveling, I access all of these apps using my smartphone via a wireless Bluetooth connection to my car's audio system.


At home, my computer can be double as my radio, too!

Some smaller market or independently owned stations require you to find their live audio directly on their web site or by loading their station app onto your device.

It takes more effort but nearly every station now streams in one way or another.

Internet reception is remarkably reliable.

I frequently make long journeys to visit my daughters at college in Boston and Delaware.

Driving up and down the American northeast metroplex, I can enjoy seamless reception via the Internet for the entire drive.

This is quite a breakthrough.

North America has never had DAB or DAB+ so now we have an Internet equivalent! Radio never sounded so nice and clear!


Old School

I feel nostalgic when I now listen to AM and FM analog broadcasts. 50 years ago, when audio choices were few and limited, American radio was incredibly local.

Entire small towns and cities would tune in to the local station hosted by live and local hosts and hostesses throughout their entire program day.

As time passed, and the listening public gained more and more choices to choose from, the number of people who tuned in to local stations declined rapidly.

To save money and improve their business model, many stations first converted from local programming to nationwide syndicated shows.


Station owners could switch on their satellite receivers and have their automation systems insert local advertising spots and IDs.

This was the beginning of 'no on-site people necessary radio.'

Today's free broadcast radio is hard on the ears! Listen to American radio during morning and evening drive times and you will often hear groups of radio hosts offer condescending banter along with endless stretches of commercials.

Many shows follow this 'Morning Zoo' concept.

At least to this one listener, inane talk combined with heavy commercial loads does not create large audiences! (but a lot of station owners think so!)

New York City has over 75 radio stations to choose from.

A rating over 5% of the audience is considered huge!

Where is the business model here?

Radio station owners now aim to produce your 'entertainment' audio as cheaply as possible and sell a lot of adverts!


This mindset carries over to engineering, as well.

When I was a young pup growing up doing beginner jobs in radio, a chief engineer would concentrate on meticulously maintaining one AM/FM station.

Now engineers are 'contract employees' (freelancers) looking after multiple stations known as 'clusters.' The art of the broadcast engineer is in the hands of 'the greys' -those old engineers (like myself) with grey hair! Everything now is based on IP and computers.


All the new 'engineers' are young computer guys! But who looks after the transmitters??

Do You Hear What I Hear?

Broadcasting nationwide radio is a great way to save money.

Radio station programs have plenty of shows to choose from.

Just put a satellite or IP receiver on the air and walk away!

No people necessary radio!

Two syndicated radio shows dominate North America.

Middays, hundreds and hundreds of stations broadcast the pomposity of the 'Excellence In Broadcasting Network' hosted by conservative talk show host Rush Limbaugh.


Agree with him or not, Rush's rants can be quite entertaining and attract large audiences across the continent.

On overnights, the ratings leader is 'Coast to Coast AM' with George Noory.

For four hours every night, George hosts an endless parade of experts chatting about conspiracy theories, extraterrestrial landings, new health cures and who knows what.

This show is meticulously produced and slick. Listen in and you will instantly understand its success.


You'll hear it on dozens of stations carrying 'Coast to Coast AM' up and down the AM dial wherever you tune in.

One other newfangled competitor for listeners is the world of podcasts.

This is public access audio at its finest. Nearly anyone can post a podcast without any prohibitions regarding content, length and quality of show or worries about distribution costs. I am sure you have heard of them and they are everywhere. Having programming at your beck and call - on demand - is very convenient!


Podcasts can also be incredibly narrowcast! Consider a podcast targeted for you and me: The Shortwave Radio Archive at https://shortwavearchive.com.

If you miss the good old days of SWLing, this is for you.

My favourite watering hole to discover quality podcasts is WNYC, New York City's premier public broadcaster: http://www.wnyc.org/podcasts.

I regularly listen to The Daily from The New York Times newspaper, WNYC's On The Media and National Public Radio's Fresh Air.


Of course, many of the world's broadcasters also offer on-demand podcasts as well. Very interesting is Radio New Zealand International's signature news programme Dateline Pacific at http://www.radionz.co.nz/international/programmes/datelinepacific.

The possibilities are endless! Yes, in the world of radio in the year 2017, the program possibilities are endless and fascinating.

Alas, there is just one thing I miss about the good old days: I live in one of the largest media markets in the world (New York City,) yet you will almost never hear direct mentions or news pertaining to my local densely-populated suburb.

At its peak, there were almost a dozen radio stations serving my area in Northern Westchester. Now there is just one FM that mentions any local news and events.

It has such a wide area of coverage that it might as well be a station from New York City.

Although I live just a few miles from a relatively large city, Danbury, CT all the radio stations from that area overlook my town because we are not in the same state!

I live in Katonah, New York which might as well be near Mars in their eyes!

In the meantime, I am listening to BBC Radio Scotland! Enjoy this crazy world we live in!

‘Across the pond’ (about HD radio in the US) -1

A BDXC member, Karl Zuk, based in NY, the US, kindly allowed me to introduce his article titled ‘Across the pond’ (about HD radio) on a BDXC’s monthly magazine.

The following description is extracted from this;


2017 has become a memorable year in the world of radio. Broadcast technology has matured into a new era of delivery.

Noise on medium wave and annoying picket fencing and capture effects on FM have finally found a cure.

No longer are North Americans restricted to traditional over-the-air broadcast ransmission. Now we listen to the Internet.

On this side of the pond, digital radio broadcasting has never been embraced as a viable method of transmission.

Instead of beginning fresh with dedicated spectrum space for digital, we were offered in-band on-channel digital marketed as 'HD Radio.'

The 'HD’ moniker only confused the public further!

The design engineers behind HD Radio had good intent but created chaotic results especially for DXers.


Digital information is broadcast on broad sidebands of analog signals cluttering adjacent channels with a relentless hammering buzz.

A strong HD Radio broadcast masks two channels high and low of the original frequency which really destroys all hope of DXing on five continuous channels!

And, oh yeah, the system really doesn't deliver.

We North American DXers has suffered through this melee since 2002!

HD Radio is difficult to receive.

Although HD capable radios are available as an option in many late-model automobiles, portable and home HD Radios are hard to find.

You need a very strong and clean signal to make HD Radio lock in.

Driving along varied terrain listening to an HD Radio broadcast can be challenging.

When the digital broadcast loses lock, the radio reverts back to analog.

The HD and analog broadcasts are never in perfect synchronicity so you will he words or upcuts as the radio automatically switches back and forth.


The AM HD Radio experience can be really interesting. The difference in quality between analog and HD is remarkable. Switching between severely frequency response limited monophonic analog to full stereo HD is profound.

You'll also hear all of your co-channel, adjacent channel, and man-made interference disappear when your radio locks to digital, as well. After all, HD Radio is

in the digital world and immune to all the noises we all know and love!

Digital signals arrive alone, not with all their co-channel friends and noise!


FM HD Radio is slightly better in sonic quality than its FM analog twin.

FM HD also has the ability to carry multiple broadcasts on one carrier.

The most popular use of FM HD virtual channels are simulcasts of AM sister stations.

Listen to Newsradio 880 WCBS in New York City when they announce their legal ID at the top of the hour: "WCBS AM and HD, WCBS FM HD-2 and WCBS online."

Enough choices?

(I am not convinced you can hear WCBS outside of the USA. WCBS is geo-locked to North America. I could not listen to them in France and Ireland. I presume the same is true within the UK.)

HD virtual channels provide some interesting listening.




In the New York City area there are several ethnic stations broadcasting via FM HD subchannels with Spanish and Russian speaking content a long with multiple alternate formats like classical, jazz and pop music variants.

Take a look at WWFS in New York City: 102.7 HD-1 is 'Fresh 102.7' - a simulcast of the primary analog FM signal. 102.7 HD-2 is 'Smooth Jazz.' 102.7 HD-3 is a simulcast of all-news WINS 1010 – an AM radio station.

Confusing and elaborate, isn't it? Even if you can decipher this maze, how many people actually listen to these subchannels? When you lose the digital signal to 102.7 HD-1, your radio reverts to analog 102.7 FM.

What happens when you lose the signal to one of the subchannels?

You hear silence! Grrr.

HD Radio also serves as a data delivery system.

I can view live color weather maps in my car that receive their data via local station's HD transmissions.


Speaking of silence, technology has some curious quirks. When digital signals drop lock, they literally disappear.

Technical broadcast types refer to this as 'falling off the cliff.' All SiriusXM satellite receivers have a built-in noise generator to lessen this aural horror.

When the bit error rate gets near the edge of losing lock, the noise generator comes on to mask the loss of signal.

Their design engineers wanted to continue the analog fade-out experience!

A similar effect is built into the design of HD Radio. When digital signals get close to losing lock a technique known as 'blending' happens. It sounds like a crossfade between two sources of audio.

Because of constant changes in digital processing delay (the amount of time and devices needed to digitize the signal) the digital signal is always out of step with the less processed analog signal.

Real time doesn't seem to exist anymore on North American radio.

Top of the hour time pips, beeps and bells almost never accurately hit at the exact beginning of an hour.

In digitized broadcast audio program chains, there is digital processing everywhere that slows the audio considerably.


My HDR-16



You speak into a microphone that attaches to a digital console. It travels over a CAT5 cable to a digital processor that eventually goes to a digital studio-to-transmitter link and/or a digital streamer for Internet listeners.

The over-the-air transmitter includes digital processing, as well.

Add more time if the program comes to you via satellite. If you listen using a digital receiver you add even a little more time!

WCBS 880 New York's time pips are heard at about 20 seconds after every hour! Digital transmission literally takes its time!

Thailand settles on DAB+ 【Viva digital Radio!】

I’ve been to Thailand twice, however both travels were only within Bangkok and neighbors, only took very short time for local radio listening.


It’s awfully friendly and fun loving, exotic and tropical, cultured and historic country.

It radiates a golden color from its glittering temples and tropical beaches through to the ever-comforting ‘Thai smile’.

 (‘24 hours service to Thailand’ on my blog)



According to ART (Asia Radio Today), Thailand’s National Broadcasting and Telecommunications Commission plans to launch digital radio in 2018 and states that guidelines should be finalized before the start of a nationwide trial.

DAB+ licenses are to be gradually sold nationwide, regionally and then locally.

The first trial DAB+ broadcasts began in Bangkok in March 2013.


Following the successful license auction for commercial digital TV channels in December 2013, the NBTC is looking to auction a number of business broadcasting services for digital radio by 2018.

The auction will be held on a phase by phase basis, and NBTC is working on the technical aspects to determine how many licenses would be made available as well as how to launch the multiplexes.


Thailand’s digital radio will be provided on Band III and the number of digital radio licenses should be enough to cover the existing radio broadcasters.

Thailand also proposes that in the future Community radio should be on low power FM.
