Here we play radio: shortwave, mediumwave, longwave, amateur/ham radio, pirate radio, utilities, digital modes, scanning and more. We share radio reviews, broadcasting news and anything we radio geeks enjoy. Welcome to the SWLing Post community!
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.”
[T]he unit is quite sensitive. RNZI evenings at 17675kHz and 13730kHz can be received various places within my house with only the internal whip. REE at 9630kHz using an external ham vertical antenna was similar copy on Pappradio (with a slight edge given to the Pappradio.)
DRM Audio while adequate, seems narrow and compressed in comparison to DReaM on my PC. I verified this by switching A to B between the Newstar and the Pappradio with DReaM using my JBL headphones. I’m beginning to wonder if the DRM audio is being processed by the DSP, just like the analogue audio. The DSP in analogue is a tad too aggressive. A real bonus in analogue is the adjustable bandwidth (1-6kHz) however. That and the DSP make analogue quite enjoyable even in the crowded 49M (6MHz) band. I have been listening to BBC on 5875kHz in the early AM with armchair copy and great audio using only the whip (throughout the house).

One of the reasons DRM (Digital Radio Mondial) has struggled to gain global popularity is that there has yet to be a portable radio solution with universal appeal.
Perhaps the future Chengdu NewStar Electronics DR111 DRM Radio will change that? According to their website, the company is certainly setting out to make an affordable receiver that is simple to operate. Hopefully, CDNSE has learned from this radio’s predecessor; ergonomics, affordability and overall ability to receive and decode DRM signals are the keys to its success.
“DRM is not seen as a profitable line for the major manufacturers,” said Sennitt. “A few smaller manufacturers have produced DRM receivers, but the unit cost is still too high, and there simply aren’t enough DRM transmissions audible at any one location to stimulate consumer demand. It’s a classic chicken and egg situation — which comes first, the transmissions or the receivers? The broadcasters and the receiver manufacturers are each waiting for the other to move first.”
