PatronX Titus SDR receiver update

A number of SWLing Post readers have been asking about the status of the Titus II portable DRM/SDR radio. I’ve been checking the project website, but had not seen an update in a long time, so I contacted the company. Mike, with PantronX, kindly replied with the following update:

As you might be aware, we have joined up with Fraunhofer to include their MMPlayer app standard on Titus–what a difference a professional decoder, for both analog, DRM(+), and DAB(+), makes! MMPlayer is full featured even including reliable one way file downloads with DRM.

We are attempting also to license HD to include on the app for North America, making a truly worldwide receiver. Some deficiencies in our version of Android have caused issues as well as MMPlayer. All of which have caused delays leading to some serious business decisions – as you can imagine. You are correct that broadcasters have made large orders that will be fulfilled first. There are units in the field testing and such and continuing resolution of the software issues.

One of the issues that folks seem to have a hard time understanding is that we can not just build a few hundred or even thousands of units. Our minimum run is 10,000pcs! To do that everything has to be 100% – including the software. We simply will not ship units that are not 100%. Titus works, MMPlayer works – its that last 5% that takes the most time to resolve. These facts preclude any incremental production attempts. All that being said, we are very hopeful that the first production run is ready by last quarter of this year.

Thank you for the update, Mike!

BBC is “keen to exploit DRM” but manufacturers must develop a multi-standard receiver chip

(Source: Radio World via Mike Hansgen)

LONDON — The BBC World Service, available on radio, TV and online, is part of one of the largest news organization in the world, the BBC.

The weekly reach of the World Service on all platforms accounted for 269 million (up from 246 million in 2015–16).

[…]Large numbers of the BBC’s audience still need international radio broadcasts.

[…]Right from its late ’90s inception, the development of Digital Radio Mondiale was fully supported and enhanced by the BBC World Service. DRM was seen as an efficient replacement for the analog AM transmissions. When we consider scarcity of spectrum for new uses and appreciate the characteristics of the radio broadcast bands, we recognize the tremendous properties these continue to offer broadcasters to deliver programs over sometimes very large distances and areas or in difficult terrain.

[…]The BBC is keen to exploit DRM in order to deliver, to key markets, BBC content free of gatekeepers in a form that can be accessed easily.

For that to be possible, the multi-standard receiver chip is required, and manufacturers must appreciate and act on this global market potential.

Kuwait updates shortwave transmitters

(Source: Kuwait News Agency via Mike Hansgen)

KUWAIT, March 8 (KUNA) — Minister of Information Mohammad Al-Jabri on Thursday opened a project updating shortwave transmitters from analogue to digital radio mondiale (DRM) broadcasting systems, at Kabd radio station.

This is a new achievement for the ministry to be added to a series of vital projects that aim to keep pace with the rapid technical progress around the globe, Al-Jabri told KUNA and the Kuwait TV.

Kabd station, through the new DRM system, will allow “Kuwait’s voice” to reach the entire Middle East region, Europe and Asia, he noted.

Kuwaitis have planned and supervised the project, the minister said, noting that updating the infrastructure of radio stations aims to cope with latest digital broadcasting development, the minister said.

Al-Jabri praised officials, and all the personnel at the ministry’s Engineering Affairs Sector, for their hard sincere efforts.

The GR-227: Gospell introduces a new SDR digital radio car adaptor

Many thanks to SWLing Post contributors Ed and Richard Langley for sharing information about the latest receiver from Gospell: the GR-227 digital radio car adaptor.

According to Radio World:

[…]The compact GR-227 can be added to car stereos, via a USB cable, in order to receive digital radio programs and corresponding data. Based on software-defined radio technology and using the xHE-AAC audio codec, the GR-227 is compatible with both modes of the Digital Radio Mondiale standard as well as the DAB/DAB+ digital radio standards.

According to Gospell, the GR-227 works with car stereos that are fitted with a USB port. Using the firm’s patent-pending technology, the adaptor behaves like a thumb drive when plugged into a USB port, making it compatible with most in-car receivers.

In addition, the GR-227 also features the Gospell Smart Tune App for Android. When partnered with an Android-powered car stereo, this lets users play back the broadcast audio program or benefit from data services.[…]

Read the full article at Radio World.

Richard comments:

“They call it an adaptor but perhaps it’s just an Android-controlled SDR receiver supplying audio output via a USB port, which could be connected to a computer or any other audio device with a USB audio input capability.”

I think he may be correct in that assumption because it may be the only way to get cross-manufacturer compatibility in a device like this.

The product information sheet noted that the receiver is supplied with a “triple band active antenna.” No doubt, the GR-227 will require adding a small external antenna to your car.

Still: an interesting product for sure! Perhaps the price point will be more reasonable that of previous DRM receivers? We’ll post updates from Gospell with the tag: GR-227

North Korea now broadcasting in DRM

Many thanks to SWLing Post contributor, Mark Fahey, who writes:

A message to contacts in North Asia (Japan / Korea etc)…

North Korea is currently (right now 1430UTC) broadcasting in DRM format on 3560KHz. Listening to remote receivers in Japan I can see the signal is very strong in the Tokyo and Yokohama areas – I assume it will be strong in other parts of Japan as well. I have NOT been able to decode the DRM successfully, I have tried piping the audio to me here in my Australian location and demodulating it with a software DRM decoder – I just can’t get a lock on the signal. Do you have a DRM receiver – could you please try? If you do manage to receive the signal please don’t forget to record it!

I’m particularly interested to know if the transmissions are relays of KCBS Pyongyang, Pyongyang Pangsong or some other service. If you get a demodulated signal could you check to see if the program is parallel to KCBS Pyongyang on 2850KHz or Pyongyang Pangsong on 6400KHz.

I have a WinRadio Excalibur with DRM here in Australia, but the signal is very weak here – far too weak to lock.

Later, Mark shared the following video by “2010DFS” on YouTube:

Mark also notes that DRMNA.info is following this story very closely and suspects that the content server and or transmitter may be Chinese in origin:

NOTE: Same frequency and bitrate as the 2012 broadcasts so this may represent “Chinese assistance”. Can anyone confirm DRM equipment in Kujang?

20170902 Update: I have received anonymous details that indicate that at least the content server is of Chinese origin. Still no word on actual transmit location. Several other Japanese (and Terje in Japan) have successfully decoded these transmissions.

Being a North Korean propaganda specialist, Mark added:

At the Freeman’s Reach monitoring station the bandwidth and microwave paths in are really being tested this afternoon with the full on activity.

All plans for the afternoon and evening now cancelled! YTN (South Korea) via Intelsat, KCTV Pyongyang via Thaicom, CNN International via Foxtel, CNN USA Domestic via Sling, Korean Central Radio and Pyongyang Pansong via KiwiSDRs – Busy!

All spectrum being captured, tonight the servers will be working hard, it will keep this place warm!

Post readers: please comment if you’re able to decode any of these North Korean DRM transmissions, and/or if you have further information about these DRM broadcasts from North Korea.

UPDATE: Mark has at least confirmed that the DRM signal is a relay of the KCBS Pyongyang national service (domestic) broadcast.
