The new Tivoli Model One Digital has AM (for Australians only)

Many thanks to SWLing Post contributor, Dennis Dura, who shares the following article from The Sydney Morning Herald (my comments follow):

Australians like AM radio, but it’s just about impossible to find a good quality digital radio with AM. Lots of digitals get FM, so why no AM?

It’s because Australia is an unusual market for radios. We’re not like Asia, Europe, Japan and America where practically all radios are designed and manufactured. These places have large populations in high densities, and one population hub is seldom far from the next. The range limitations of both digital and FM are seldom an issue.

But in Australia we have digital broadcasting only in the capital cities, meaning Brisbane’s digital radio stations are 900 kilometres from the next nearest in Sydney, leaving about 800 kilometres of dead air between. Digital can’t even hold between Sydney and Canberra. FM lasts a bit longer, not much. But with good old AM you can listen to Darwin from the Nullarbor Plain when the conditions are right. Through vast tracts of Australia if you don’t have AM you don’t have radio.

So Gary Tye’s challenge when he took on distribution of the Tivoli brand was to convince people in Boston that Australians will actively seek out and buy a digital radio with AM. They took a lot of convincing.

And so the $449 Tivoli Model One Digital is now available with AM, as well as FM and digital. But only in Australia. Caravanners around this wide brown land will rejoice; there’s at last a good sounding digital radio that will work anywhere.

[…]The sound quality is, as a very honest department store salesman observed, good but not great. I remember the original as being better. The bass can become ragged down low and the definition gets a bit fuzzy at high volumes, but for filling a study, a kitchen or indeed a caravan with good music the Tivoli does an entirely respectable job. It’s not on a par with a Wave Radio but it costs half as much and sounds better than the vast bulk of radios, be they digital or analogue. And it has AM.

It also has Spotify, Tidal, Deezer and Wi-Fi to get internet radio. There’s Bluetooth and you can hook in your phone or music player with a cable to the 3.5 mm auxiliary input.

Thanks for the tip, Dennis!

I owned the original Tivoli Model One and loved it. I recently gave it away while thinning the herd here at SWLing Post HQ. Though it was an elegant, simple radio with excellent audio characteristics, so is my Como Audio Solo which essentially replaced the Model One.

While the Model One Digital is appealing in many respects, reviews are lukewarm at best. Customers complain about the proprietary app, the audio being too heavy on processed bass and the overall performance not matching that of its predecessor.

While the Model One Digital is a “WiFi” radio, it doesn’t seem to connect to any of the streaming radio station aggregators we radio enthusiasts rely on to tune to our favorite obscure local stations on the other side of the planet. It appears to only connect to paid music streaming services and one’s own local digital library (though please correct me if I’m wrong about this!).

Post readers: Any Tivoli Model One Digital owners out there?  I’d love to read your reviews!

Dave’s review of the AOR AR-DV1 Digital Voice Receiver

Many thanks to SWLing Post contributor, Dave Zantow (N9EWO), who has recently posted his review of the AOR AR-DV1 digital voice receiver.

As with many of Dave’s reviews, this evaluation takes a close look at HF and mediumwave performance which isn’t the AR-DV1’s strong suit. Dave notes:

“[Though] not what the receiver was designed for, RF performance on MW / HF bands (and the terrible audio quality) are mediocre at best.”

Thanks, Dave! Your review reflects comments I’ve received from some Post readers who’ve purchased the AR-DV1 as well. Many were particularly upset with the audio quality. Of course, the AR-DV1 is marketed as a digital voice receiver, thus audio likely favors “narrow” voice audio.

BBC mothballs idea of forced move to digital broadcasting

BBC to keep broadcasting on FM

For years fans of wireless radios have campaigned to stop the apparently inevitable march of progress as Britain prepares to switch off its crackling analogue signal and become totally digital.

But now, the BBC will announce that it has shelved plans to force listeners to replace their analogue radios with DAB sets.

In a move that will also be welcomed by the two million motorists with analogue car radios, the corporation will admit for the first time that FM broadcasts must continue to keep audiences on side as music streaming and podcasts threaten its traditional strongholds.[…]

At $20 billion in debt, iHeartMedia files for bankruptcy

(Source: NPR)

The “substantial doubt” that iHeartMedia’s corporate leaders expressed around the company’s likelihood of surviving another year, mentioned in its quarterly financial report last November, has been put to rest.

iHeartMedia, the country’s largest radio broadcaster with around 850 stations and a leading outdoor advertising company, is filing for bankruptcy after spending years trying to manage its $20 billion in outstanding indebtedness. (For some context, per that November statement, iHeartMedia was obligated to pay $1.8 billion in interest over that coming year.)

The company writes in a press release that it has reached “an agreement in principle with holders of more than $10 billion of its outstanding debt and its financial sponsors” that will essentially cut its debt in half, and that it has filed motions with the court to be allowed to operate normally through the restructuring. The bankruptcy follows, by two months, the bankruptcy of the country’s second-largest radio company, Cumulus, which offloaded $1 billion in debt.[…]

Radio Survivor: Exploring and Preserving the Brooklyn Pirate Radio Scene

Check out this brilliant episode of the Radio Survivor podcast which features our Shortwaveologist friend, David Goren along with John Anderson of Brooklyn College:

(Source: Radio Survivor)

There are more unlicensed pirate radio stations in New York City than licensed stations. The borough of Brooklyn is a particular hotspot. Producer and journalist David Goren has been researching and recording these stations so that their ephemeral nature isn’t lost to history. To help preserve this legacy and make it accessible to a wider audience he’s constructing an interactive map of Brooklyn pirates, due to be released later this year.

David joins us on this episode along with Prof. John Anderson of Brooklyn College, who has been tracking and researching unlicensed radio for two decades. We discuss the unique qualities of Brooklyn pirates, and how they fulfill the needs of communities that are underserved by other media, why it’s important to preserve their legacies, and why the expansion of low-power FM failed to provide sufficient opportunities in cities like New York.

78 Megahertz: Australian astronomers detect signal from the dawn of the universe

Astronomers detect signal from the dawn of the universe, using simple antenna in WA outback

They have picked up a radio signature produced just 180 million years after the Big Bang using a simple antenna in the West Australian outback.

The ground breaking discovery, reported today in the journal Nature, sheds light on a period of time known as the “cosmic dawn”, when radiation from the first stars started to alter the primordial gas soup surrounding them.

[…]The signal they’ve been looking for is a miniscule fraction — between 0.1 and 0.01 per cent — of the radio noise from the sky.

“It’s like trying to hear a whisper from the other side of a roaring football stadium,” Professor Bowman said.

The signal is also within the lower range of FM radio, so finding a place on Earth that is free of human radio interference was essential.

That’s why Professor Bowman and colleagues decided to base their experiment at CSIRO’s Murchison Radio-astronomy Observatory, 300 kilometres north-east of Geraldton.

“Going to Western Australia and working at the Murchison Radio-astronomy Observatory was an absolutely critical first step for us,” he said.

There they built a small table-sized radio spectrometer with a radio receiver attached to two metal panels that act as an antenna. Akin to a set-up from the 60s or 70s, the EDGES instrument is much simpler in design than bigger array telescopes around the world.[…]

The importance of community radio in Guatemala

(Source: Aljazeera via Mike Hansgen)

Despite the legal challenges, Indigenous communities use radio to ‘keep their language and culture alive’.

Sumpango, Guatemala – Sitting in a courtyard, wearing an indigenous huipil dress, Amanda Chiquito glows as she talks about the challenges and successes of working with the community radio station in Sumpango Sacatepequez, Guatemala.

“There is no media that represents our community,” the 25-year-old says.

“There wasn’t a media outlet that could inform us and keep our culture and language alive,” she tells Al Jazeera.

Chiquito is a reporter and radio host at Ixchel Radio, the only community station in Sumpango Sacatepequez, a small town 42km from Guatemala’s capital.

More than 95 percent of the town’s 50,000 inhabitants are indigenous, living in remote areas, where access to information and technology is limited.[…]
