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.[…]

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

Titus SDR, a division of PantronX, says the Titus II multi-standard digital radio receiver is ready for production.

The consumer software-defined radio digital receiver platform, which is the result of collaboration between Titus SDR/Patron X, Jasmin-Infotech, TWR, and Fraunhofer IIS, supports multi-standard radio reception, including DRM, DAB and DAB+ and core data applications. The system is based on a custom Android tablet platform, featuring multipoint touch, WiFi/Bluetooth and stereo sound.[…]

Radio World explores the PantronX Titus II

Many thanks to SWLing Post contributor, Tom Ally, for sharing the following article by James Careless in Radio World:

Well, if you are the engineering firm PantronX, you have the Titus II software-defined radio. And when you plan to sell this ultimate receiver for less than $100 each, you hope you have a consumer sensation for the worldwide broadcast market.

Unveiled by the Panama-based company at an international broadcasting meeting in Miami in August, the Titus II SDR is not yet shipping. But it is described as capable of receiving and playing analog and digital radio transmission formats including AM, FM, shortwave, HD Radio, DAB+ and Digital Radio Mondiale. The company is considering adding a DRM+ decoder.

The initial market is among worldwide broadcasters, particularly those serving countries where listeners may lack internet; a secondary market is individual listeners, hobbyists and others. PantronX will not supply all decoders for all formats but add them preloaded as needed.

Radio World: Schenectady Shortwave Transmitters, 1941

philco38-4_dial_1Many thanks to SWLing Post contributor, Dan Robinson, for sharing a link to the following article in Radio World:

The General Electric Co. was truly among America’s premier broadcasting companies.

In addition to developing much of early broadcast technology and building a trio of high-power AM stations in the early 1920s — WGY Schenectady, N.Y.; KOA Denver; and KGO Oakland, Calif. — GE was also the country’s pioneer shortwave broadcaster.

GE’s initial shortwave station, 2XI, first broadcast in 1923, and in 1924 it was used to relay WGY’s programs for to KOA and KGO for rebroadcast in the western U.S.

By 1925, there were two experimentally licensed shortwave stations in Schenectady: W2XAD and W2XAF. A third GE station in San Francisco, W6XBE, was added in 1939.

That was the year that the Federal Communications Commission allowed the country’s experimental shortwave stations to relicense as commercial operations, and these three GE stations received the call signs WGEA, WGEO and KGEI, respectively.

Radio World: International Broadcasters Reconsider Shortwave

Sackville-radio-towers-li

Check out this article from Radio World which addresses the state of shortwave radio broadcasting.

Jeff White of WRMI and Kim Elliott of the VOA are both interviewed. Elliott even speaks about the virtues of the VOA Radiogram experiments which have had success circumventing shortwave radio jamming (broadcasts which were completely omitted from the BBG Special Committee report on the efficacy of shortwave radio).
