So what are the chances of a new stand alone DRM radio this year ? The chipset is available so when ?? Talk of June but nothing heard about this recently

DRM still seems to be stuck in the anorak stage. Come on RTL etc hurry up !!

I stated this a few weeks back, as nothing is really moving forward, this day & age it should be, it still sounds like test transmissions to me, I like the idea of DRM but boy is it slow, and the stations so slow.

Since nobody in the DRM consortium actually seems to be interested in commercialisation in the near future, perhaps they should put their boffin hats on (as usual) and come up with an integrated standard for a DAB(mulitplex approach)+DRM(stand-alone station approach) + any of the following:

DAB (multiplex approach, but using AACPlus as the compression algorithm);

DRM (up to 120MHz with a multiplex approach);

DRM (up to 120MHz with a stand-alone station approach).

I still says the fact that DAB uses an old inefficient compression standard is a problem. New receivers should be compatible with DAB as it is, but should also be a compatible with a new standard which uses a better codec + be compatible with DRM (ie AM broadcasting).

Chances of a receiver that does all this in the near future: none.

One should not forget that a lot of the driving members of the DRM consortium are shortwave radio stations which are essentially government funded bureaucracies left over from the cold war looking to justify their relevance in the world (why are these stations funded at all nowdays???). They are probably totally illequipt and inexperienced to be able to design and commercialise something quickly (well, that's what it seems like anyway). More mainstream commercial companies (eg Sony etc) should be ACTIVELY ENCOURAGED to take over leadership.

I don't know when the famed consumer receiver will come out, but I know I will buy one as soon as it is available!

I'm afraid the World Traveller can't really be counted in, because it wouldn't work with a Mac.

I would only hesitate in buying a portable DRM RX today if it cost much more than €200.

Yes ditto I have my debit card numbers ready to quote! I really think the price could be about the £200 mark though (about 300 Euro) is'nt the radio meant to include DAB also ?

Does anyone have any details phone numbers etc ??

Has anyone heard anything new on stand alone DRM shortwave receivers?

Did the chips get released yet?

Nothing as of yet, but even if they were available there's nothing really on DRM for joe public so there's no hurry.

I think you should keep in mind all the ex-patriots who want to listen to news (and soccer) from their home countries. British ex-pats in Europe, german ex-pats on mediterranian islands etc.

Well, a lot of them already have TV from their home countries and satellite radio but they may want to listen when driving around in their cars as well.

It's not only those who wait for RTL to broadcast to the UK again after many years (if they will ever do so again at all...).

Wait until autumn when IFA will be held in Berlin. I guess, manufacturers will not come out with any information before that date, even if they had receivers ready now. Anyway, they should have their prototypes ready by about now, if they are going to present commercial models at IFA.

There is an article in the BDXC's magazine Communication a report about DRM and mentions that the DRM chip is ready, this was back in February!

But as I said on the ukonair forums about BigL relating to MW we need stations to be broadcasting first before the DRM receiver comes out not the other way round, some chance though. Chicken and egg situation. LIke with DAB I'm sure stations were transmitting already when DAB radios were ready to buy...

Hi Ron,
to answer your question about the chips, there was an article in Electronics World (April issue) about TI and Radiscape working on the combined DAB/ DRM chip:

...The DSP (edit: on the current DAB module) handles all the algorithms necessary to mix down the RF signal to an IF, digitise it, send it to the baseband hardware for sychronisation, demodulation, decoding, buffering and error checking among other tasks.
Tackling DRM is slightly tougher, as it is a low- bit rate standard aimded at replacing the analogue signals below the 30 MHz range...

"This will be a single DSP chip. DRM makes things more complex, for a start you have four codecs at the outset, but we are confident that we will not experience any major snags in delivering this chip." (Radioscapes VP of Marketing)
Although neither company confirmed which exact DSP engine will be used in the new DAB/DRM chip, they conceded that such combined radio modules will be ready this year, and receivers on the market in time for Christmas 2005.

Concerning Rx, I don´t expect anything would be presented before IFA in Sept.

73, Simone

Thanks for all the comments.

I was hoping for a low cost standalone DRM radio that I could take and listen to a couple of the SWL broadcasts I listen to almost every day on my computer and my winradio 303i whne I go to the shore.

Oh well. I'm out of luck i guess.

That would be great but unlikely, I'm sure the manufacturers want to make as much profit as possible or am I being to cynical / pessimistic ?!

Around the £100 make is about the right figure I think

This is true, but they would double if not more at £50 so things would move quicker.

Over at http://www.usdrm.com/05USAMTG.html you can read the notes from DRM USA's May group meeting, and it mentions receivers a few times. I've pasted the most detailed quote below:

"Don Messer said that the target price for the two to four new models of DRM receivers that should be available by December of this year is 100-150 euros. He said that some large companies are currently interested in developing DRM receivers, but he said that small manufacturers may indeed get DRM off the ground. Adil Mina of Continental Electronics said that Texas Instruments is developing a DRM chipset, but they are reluctant to give out any information about it at the moment due to competition. There are indications from the mobile telephone industry that they are looking into DRM radio in cell phones."

Great price!! As cheap as DAB sets!
But of course the plural of euro is euro, not euros… spelt differently but spent all the same!

Thanks for the link. It sure is a breakthough. The audio link about the news is a 'must listen'

There is a press release from radioscape at http://www.radioscape.com/downloads/Press_Release/RS504052_DRM_RS500module.pdf

Price is not as cheap as some other sources I've read heard about though but still good for new technology. I hope the manufacters using the module don't try to 'cash in' and inflate the final price, have a feeling they might

In the past, the "early adopters" of any new technology have always been milked.

Hi,

Swedish Radio and SR International/Radio Sweden will host DRM’s quarterly board meetings in Stockholm from June 14-16.
Will anybody attend this meeting?

Here is some information about what will happen at IFA (a giant consumer electronics show in Berlin) next month.

RADIOSCAPE TO SHOWCASE DRM/DAB RADIO RECEIVERS AT IFA 2005
World’s first affordable, integrated,
multi-standard, digital radio receivers

London, UK – 11 August 2005 – RadioScape, the world leader in Software Defined Digital Radio solutions, will be showcasing multi-standard digital radios based on its recently launched RadioScape RS500™ module at IFA 2005 in Berlin, Germany (2-7 Sept 2005). RadioScape has worked with several leading manufacturers who will be launching their digital radios at the show that will be able to receive DRM™ (Digital Radio Mondiale™) as well as DAB (Digital Audio Broadcast), FM with RDS, LW, MW and SW.
DRM will be featured at two IFA locations this year, where the new DRM/DAB radios will be on display. The DRM receivers booth in Hall 5.2, which is organized by RTL Group, Deutsche Welle, Radio Netherlands, BBC, Deutschlandradio, Voice of Russia, Truckradio, DRF, Radio de la Mer and Littoral AM, where participants will be discussing their plans for DRM services across Europe, and the DRM Consortium booth in Hall 5.3 (TWF), which focuses on DRM products and technology.
“IFA is one of the most important consumer electronics events and is the perfect showcase for the first, consumer-priced DRM/DAB radios,” said Dave Hawkins, VP of RadioScape’s Receivers Business. “This will really help DRM take off with the general public. Our unique software architecture has enabled us to create cost-effective, multi-standard, multi-application modules by using software stacks running on a powerful Texas Instruments DSP engine. DRM is a complex technology, but our expertise in developing with many other radio standards has enabled us to create and verify a complete, multi-standard radio solution in record time. DRM broadcasters have been waiting for the launch of consumer-priced receivers and, through our close cooperation with a number of leading radio manufacturers and broadcasters, we will enable this to happen right on schedule for the run up to the 2005 Christmas market. DRM will be the hot technology at IFA this year with many broadcasters and manufacturers making DRM announcements. As a result, 2006 will be the year that DRM becomes mainstream.”

The RadioScape RS500 module
The RS500 supports capabilities such as the highly popular Pause, Rewind and Record to MMC card features as well as the ability to display and use Electronic Programme Guide (EPG) data. Modules are sampling now to select customers and will be generally available after IFA. RadioScape forecasts that multi-standard, multi-band receivers based on the RS500 could have end user prices below $250 -- almost a quarter the price of existing DRM receivers in the market.

About DRM
DRM is the world's only, non-proprietary global standard for the digitizing of short-wave, medium-wave and long-wave broadcasting. Additionally, the DRM consortium recently voted to begin the process of extending the DRM system into the broadcasting bands up to 120 MHz. Able to cover great distances and provide near "FM quality" audio using lower transmission powers and compatible channel allocations, DRM is currently being adopted in markets worldwide to provide new and higher quality broadcasts for local, national and international audiences. Over 20 Broadcasters are already broadcasting using DRM across the globe and include the BBC (World Service), Deutsche Welle, RTL Group, Radio Netherlands, and TDF. More information can be found at www.drm.org

Goodie! Soooooo… how does one assess the performance of a radio inside a big conference hall?

If any of you have experience of what sort of FM and LW/MW/SW stations should get through to such an environment, in Berlin, perhaps you could post some ideas that could help us assess the receivers on show?

Perhaps it's more realistic just to assess the user interfaces though!

They'll use some kind of long wire arrangment for an antenna re SW reception as for DAB reception in Germany hmm they may have a problem as DAB is just about dead in Germany now. Still it's the DRM part which will be the selling point. I feel sure that the manufacturers who buy the module will slap anotrher x amount on to the price making the end cost probably around the £200 mark

I presume who ever goes ahead has been working on a design already as to incorparate the module into a new radio in 3 1/2 months seems a bit of a challange ??!

Not if the Recever maker already uses Radioscapes exsting DAB module because it is pin compatable with the new DAB/DRM module. The main task will be to add an AM antenna.

The $250 price assumes that the manufacturer will add the same mark up as they do to the DAB receivers.

Does the RS500 include a full rf section, or do the manufacturers need to add that themselves? I couldn't quite understand that part of the press releases!

Radioscape list Roberts Radio as one of their clients for DAB modules.

Roberts radios are made by Sangean, and we know Sangean make good short wave portables, so we can hope the rf end of the new radios will be pretty good, if it is separate from the module.

Anyway, maybe Roberts will be selling DRM radios by the end of the year –_if so that should mean widespread availability in the UK.

Ofcom have no interest in DRM, all they want to do is promote DAB it would seem

It pretty much looks as if the module already contains the RF section as do the already available DAB modules from Radioscape.
Also, it has got an RF-F-connector mounted on it like it can be found on any standard satellite tuner.
So, if the RF section is of a quality type, which it should, it will also receive other shortwave services well.
"All" a manufacturer has to do, is to add an audio amplifier with speaker(s), a case with knobs, a display, a human interface microprocessor with software, a power supply and perhaps a few additional band splitters connected to separate RF inputs and probably also a ferrite antenna. A manual, explaining all the new capabilities to the customer (who will certainly be one of the so-called "early adopters") will have to be written and printed as well. Still quite a bit to do until Christmas. :)

Customers will perhaps also want to buy a suitable antenna, a desire which also has to be satisfied. This should not be overlooked, since the overall satisfaction with the new receiver may largely depend on this essential by-product. Also, I guess, more money can be made by selling such an add-on than on the receiver itself.

DRM Plans For Big Receiver Push at Upcoming European Shows

As more HD Radios come on the market this fall, so too will Digital Radio Mondiale-capable radios for short-wave, medium-wave/AM and long-wave. While software and high-end DRM-capable receivers have been on the market, what marketers are billing as the first affordable consumer-grade Digital Radio Mondiale-capable radios are expected to be on display at Europe's media exhibitions IFA and IBC in September.

The hardware release will coincide with commercial and public broadcasters announcing new and extended DRM broadcasts.

Texas Instruments and RadioScape will unveil several manufacturers' multi-standard consumer receivers with DRM, Eureka-147, FM, RDS, LW, MW and SW capabilities based on TI's DRM350 multi-standard digital radio baseband.

Coding Technologies, AFG Engineering GmbH and Himalaya (Power) Electronics will present a DRM-capable radio based on Analog Devices' Blackfin.

While DRM currently covers the broadcasting bands below 30 MHz, the DRM consortium voted in March to extend the system to the broadcasting bands up to 120 MHz. DRM and the World DAB Forum, which promotes the Eureka-147 form of digital radio technology, are combining efforts on the design, development and testing of DRM's extension and expect that joint hardware to be completed by 2009.

Wishes, Andrea
