A new portable DRM/DAB receiver by Starwaves GmbH

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

There is a new digital receiver available. It can receive DRM in all bands from low, medium, high and band 1 & 2 VHF, as well as DAB+ and analog AM and FM.

It cannot receive HD radio because Xpedia charge licensing fees on every receiver and the market is restricted to USA and Mexico.

Thank you for the tip!  It appears this receiver is a product of  STARWAVES GmbH, Germany/Switzerland, although I assume it’s manufactured in China based on the bulk order costs.

I’ve reached out to the manufacturer for more details as there are few specifics and no specifications on the Alibaba page.

There are also no details about this radio on the Starwaves website.

If/when we receive more information about this radio, we’ll share it here on the SWLing Post. Stay tuned!

The NSA’s Software Defined Radio application “RedHawk” is now open source

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

Not kidding, a friend told me that NSA released a bunch of software to open source, the main list being here:

https://code.nsa.gov/

While looking at the list of projects on that page, halfway down the page, I found a project called “RedHawk” which is described as:

“A software-defined radio (SDR) framework designed to support the development, deployment, and management of real-time software radio applications.”

Now, being curious I opened the github link:

https://github.com/redhawksdr

[It] contains quite a number of subprojects, modules and other stuff, then I checked the main “RedHawk” project:

https://github.com/RedhawkSDR/redhawk

Here’s the documentation:

https://redhawksdr.github.io/Documentation/index.html

It seems really interesting; apparently it allows to define a wealth of processing stages (e.g. filters, converters…) and connect them to process signals coming from an SDR; I think it may be a very interesting and useful tool to fiddle/experiment with SDR receivers, if I’m not wrong it may allow to push an SDR to the limits, improving its performance, and may also be useful to write SDR software!

Fascinating! Thank you for the tip, Andrew!

Post Readers: It appears this project has been in the public domain for a little while. Please comment if you’ve tried implementing RedHawk in your SDR system!

Talking shortwave and spectrum on the Radio Survivor podcast

Last week, I had the honor of speaking with Eric Klein and Jennifer Waits on the excellent Radio Survivor podcast. It’s rare that in one show I get to spread so much shortwave radio love–thanks for making that happen Radio Survivor:

Perhaps you are like me and you have wished that you could go back in time and spin a radio dial and just listen to and browse the full radio spectrum from another time and place. Our guest on the show, Radio Anthropologist Thomas Witherspoon, is building a website for just such a thing. It’s called the Radio Spectrum Archive and it is not magic, it uses a piece of technology called a software defined radio that makes recording a full spectrum of Shortwave, AM and even FM radio (if you have the computing power to handle the load) a very real possibility. Thomas Witherspoon is also the primary contributor to The Shortwave Listening Post (www.swling.com) so we are going to learn a few things about the wonder that is shortwave radio on planet earth.
