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.

Additionally, if you’re interesting in following DRM news, check out the excellent DRMNA blog.

Post readers: anyone have more information about this new DRM broadcast site?  Please comment!

Video: Lightbulb vs Radio Beacon by Thomas Cholakov (N1SPY)

3 Replies

Many thanks to SWLing Post contributor, Ivan Cholakov (NO2CW), who writes:

My 11 year old son Tommy (N1SPY) completed a project where he compared a 1W lightbulb to a .25 W radio beacon that he put together and bet that the radio beacon can be heard around the world. I asked him to document his activities as he went along. The project took a couple of months but is now complete and we stitched together a video of his activities.

Click here to view on YouTube.

Wow–Tommy, you’ve done an amazing job here!

I especially like how you’ve taken time to explain the principles behind the various steps of the process. Brilliant job!

Tommy, your future videos are always welcome here. Keep up the good work and we’d love to hear how many new countries you’ve racked up on your WSPR system!

VOA Radiogram to end (Viva La Radiogram!)

VOA Radiogram, 20-21 May 2017: Special doomed edition

I will retire from the Voice of America on June 23, after 32 years as audience research analyst and broadcaster.

I was hoping to continue to produce VOA Radiogram as a contractor.  I approached various BBG and VOA offices. They all declined.

And, therefore, the last VOA Radiogram will be the weekend on June 17-18

Money is not the issue.  I am willing to work cheap.  My main interest is to be authorized to continue the show and maintain a VOA email address, so that I can keep in contact with the audience.

The irony is that, after retirement, I will finally have time to answer your emails – but I will no longer have access to the VOA email system to do that.

But, the show must go on.  In addition to the four weekly transmissions via the BBG North Carolina transmitting site, VOA Radiogram is also broadcast on WRMI in Florida twice on Sundays. I can hardly allow those half-hour slots to be filled by light recorded music. So, beginning the weekend of June 24-25, a program similar to VOA Radiogram, but with a new name and email address, will be broadcast by WRMI.

More about the demise of VOA Radiogram, and the emergence of its replacement, in the weeks to come.

Many thanks to SWLing Post contributor, Richard Langley, who writes:

There was a segment on the latest episode of AWR’s Wavescan (9 April 2017) about the Titus II DRM receiver recorded during the recent HFCC meeting in Jordan. In it, it was stated that the shipment of the first 1500 units was expected at the end of March or by the first half of April. Included some discussion of added shielding to prevent digital noise and the high-sensitivity of the receiver compared to other DRM units. Streaming and download of the Wavescan episode is available here:

Many thanks to SWLing Post reader, Pradip, who shares the following story from Radio and Music Biz online:

AIR has acquired 37 DRM transmitters, in talks to get cheaper radio sets

NEW DELHI: All India Radio (AIR) has introduced digital radio technology in the AIR Network by installing new state of the art Digital Radio Mondiale (DRM) Technology transmitters by replacing old outlived 37 Medium Wave/ Short Wave transmitters.

Minister of State for Information and Broadcasting Rajyavardhan Rathore told Parliament however that the provisions contained in Policy Guidelines on expansion of FM Radio broadcasting services through private agencies (Phase-III) do not provide for private FM broadcasters to adopt digital radio technology.

He said Digital Radio allows significant improvements in service reliability, audio quality, more radio services and higher efficiency.

The new AIR transmitters include 35 new state of art technology Medium Wave (MW)/ DRM transmitters as a replacement of old technology valve based MW transmitters. Additionally, two new state of the art technology Short Wave (SW) DRM transmitters have been approved for installation as a replacement of old SW transmitters.[…]
