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, 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.
