Do not bother with the smaller 7" WinBook, it has inherent battery management problems that make it unusable, but the 10" model is fine at 2.5msps and since it has two USB ports, can be left attached to Airspy/SpyVerter and kept fully charged indefinitely. 73, Bob W9RAN

Re: SDR applications that support HD-Radio : was New review of the Airspy R2 for FM DX
David Ranch
Well, I would think (hope) that iBiquity (now DTS) would be open to some licensing mechanism. This whole situation reminds me of the DVSI/AMBE chip situation we have for Dstar/YSF/DMR as well. I do grasp all of the potential complications of how to fund the initial license, legal wrangling, accounting of licenses/renewals, and the various technical hurdles to actually implement all this but I do think there is a market for it. The question is if it's large enough to support the effort. I know that SDR# supports plugins, Gqrx could support it if there was a GnuRadio module written for it, etc. but having to provide binaries for various OSes and their respective versions gets difficult in a hurry. I would much prefer source code but being patent encumbered removes several Linux distros from the mix right out of the box. Simon: You expressed some interest here. Any desire to pursue? Ezio: Thanks for the link to the book: Radio’s Digital Dilemma: Broadcasting in the Twenty-First Century (Routledge Research in Cultural and Media Studies) by John Nathan Anderson (Author) . I'll have to give that a read! --David KI6ZHD

Zoom FFT
Feeling thick today! Trying to get the two Zoom FFT spectra working, and while I have the two displays (or three with MPX), the displays are empty.
I've obviously missed a step, but what step? Thanks, David -- SatSignal Software - Quality software written to your requirements Web: http://www.satsignal.eu Email: david-taylor@blueyonder.co.uk Twitter: @gm8arv

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.... {^_^} (As a certified woman I suspect I lack the balls required....)

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:

Besides the US, HD-Radio is also used in Canada and Mexico. Not sure about anywhere else.

Thank's a lot.
What sample rate are you using? 10mhz ? or 2mhz?

Re: Android app
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?
