Hi David,

Here is the reason:
"A company called iBiquity Digital created the technology to make this
happen. They license this technology to radio stations and consumer
electronics manufacturers"

This implicates they do not give it away to SDR developers for free.

Thanks for the link as that was an interesting read. That does bring
up a question that I've been unable to find an answer to:

Why don't any SDR applications ideally on Linux (Gqrx) but even on
WIndows programs (SDR#, SDR-Console, etc) support HD-Radio?


Is this a licensing issue? Couldn't this be resolved via a commercial
plug-in? Maybe there is some available software that CAN do this?

Probably not. However, the GitHub tool could be leveraged so that the user "compiles" it themselves and link it into your program if the interface for additional demodulators was made public.

The real problem is that this would need a compiler on the user's machine, at a minimum. Now, if somebody had the balls to go off and compile a version for Windows as a DLL....

Licensing issue with a proprietary format and rapacious lawyers involved.

I know it works on the Dell Venue 8 and Chuwi hi8, but there are even cheaper tablets that could do the job like the TW700.


Re: SDR applications that support HD-Radio : was New review of the Airspy R2 for FM DX

 

There is an open-source HD decoder project on github that was apparently developed for  RTL-SDR dongle receivers:

 

https://github.com/theori-io/nrsc5

 

The developer also has posted a paper online on the topic of the  HD protocol and a lot of the technical details:

Hello Alan,

Yes, HD-Radio is a USA centric (or is that exclusive?) technology and yes, it's strange that there isn't much SDR software (free) developed in the USA either.  There are some programs out there that can decode DAB now but still, no HD-Radio.  If I was to guess, it has to deal with patents, licensing, etc.. but I would think this would be addressable via an SDR plugin with a sprinkling of DRM (shudder).

I still think there is a market out there for this though.

Thank's a lot.

What sample rate are you using?

10mhz ? or 2mhz?

Well said and understood, thank you!

So, could you please suggest a cheap but good enough Windows tablet that can run SDR SHARP & AirSpy decently enough?
