FCC: A detailed application for a new 10KW DRM transmitter

Many thanks to SWLing Post contributor, Ed, who writes:

Thomas, did you see this? It’s a detailed application to the FCC for the construction of a 10KW shortwave transmitter for DRM on 9.65 MHz and 15.45 MHz.

Click here to download the application (PDF).

Thanks, Ed! I know nothing about Turms Tech other than on their FCC application, they list their business is “broadcast and data.”

Another SWLing Post reader forwarded the following from this article in Radio Mag Online:

“Of interest in the U.S. is the recent application of Turms Tech LLC to broadcast DRM from New Jersey toward Europe and the Middle East. Specifically, they plan on using the Armstrong tower, just west and north of New York City, with yagi-type antennas, generating an ERP of 10 kW on 9.65 and 15.45 MHz.”

The Radio Mag article is worth reading in full as it includes a number of DRM news items.

AIR Launching DRM Conversion, Phase II

NEW DELHI — All India Radio was recently congratulated by India’s Union Minister for Information and Broadcasting Shri Venkaiah Naidu for having completed phase I of the national DRM digital radio roll-out in India. Thirty-seven DRM transmitters have been installed by AIR throughout the country, and all are now operational, according to DRM news.

Of the 37 new transmitters, 35 are medium wave and 2 are shortwave transmitters. Both SW transmitters are for international service and are broadcasting in pure DRM. […]

AIR is now in the process of launching phase-II of the DRM project by offering full features and services from these DRM transmitters and further improving service quality. When Phase-II is complete, the full-featured DRM services will be available to the audience and a public information campaign will be initiated to inform the Indian citizens of the completely new and future- oriented DRM radio platform and its many benefits. […]

Phase-III, as presented by AIR, will eventually culminate in the complete transition of radio services to the digital DRM platform, further improving the number and quality of radio services and extra features for the listeners, while also saving tremendous amounts of transmission power every year, according to the same article.

While it sounds like the broadcasting side of DRM is progressing with AIR domestically, I haven’t read anything recently about affordable DRM receivers being developed for the market in India (other than possibly the Titus II and Gospell GR-216 which, I suppose, could be imported).

Based on messages I’ve received from readers/listeners in India, any new DRM receiver must be very affordable ($40 US or so) if wide adoption is to be expected.

I believe this is an opportunity for a manufacturer like Tecsun to step in and make an affordable DRM portable for the market in India–something with a simple display and controls. Otherwise, this might be another “cart before the horse” situation for DRM.  That would be sad.

Titus II at NAB

The least expensive portable DRM receiver on the horizon could be the PantonX Titus II (not yet in production).  PantronX has claimed the Titus II will cost “less than $100.”

And speaking of the Titus II, SWLing Post reader, Ed, notes:

pantronX is reportedly going to announce its Titus II Android SDR boombox at NAB April 22-27, which is another indication this radio is for real.

We’ll post updates about the Titus II as they become available. Follow the tag: PantronX Titus II

pantronX Titus II quick update

Many thanks to SWLing Post contributor, Ed, who notes:

I just received a status update on the pantronX Titus II portable SDR from Mike, their chief engineer.

Mike said the self-contained SDR portable will include “SoapySDR as the interface to make it much easier to roll your own SDR app.” Here’s some info about SoapySDR:

Mike also said, “To be 100% truthful, our biggest push right now is for the international MW & SW broadcasters. They want to go DRM digital is the worst way!”

Thank you for the update, Ed! Click here to view the pantronX website.

PantronX Titus II update

Many thanks to Mike at PantronX who has provided the following update on the Titus II portable SDR:

As you can imagine the response to Titus has almost been overwhelming! Pre-orders far exceeded our imagination and excitement from broadcasters has been very loud. DRM and digital broadcasting seems to be reinvigorated with Titus in 2017. I think we really broke the price barrier that most everyone has been dreaming of and provided the flexibility
that has held back the cause.

As posted on http://hfcc.org/delivery/receivers.phtml

‘Update on availability received from PantronX: “We have been overwhelmed with the response to Titus with orders and request – coupled with an early Chinese New Year that the pre-production date has slipped a bit. Please be patient as we work with our suppliers and add more functions.” ‘

We are doing all we can to push – Chinese New Year is a crazy time – the factories are shut down for 3 to 4 weeks and as you can imagine the stress prior to and the performance after.

Hopefully in the next couple of weeks our http://titusradio.com/ website will undergo a much needed update. So much to do – but we are making good headway.

Thank you, Mike! I’ve had a number of readers asking about progress on the Titus II, so I appreciate the update!
