[Discuss-gnuradio] EAS/SAME Decoding?

How would one create a SAME decoder in GNURadio? EAS being the Emergency Alert System, AMBER alerts, etc. I can tune to Weather radio; but I was wondering if I could listen to the EAS channels themselves. EAS: http://en.wikipedia.org/wiki/Emergency_Alert_System Thanks. ___

[Discuss-gnuradio] ISDB-T Modulation?

I am aware that ATSC, and various forms of DVB-T/2 modulators exist in GNURadio both with standard and custom blocks; but is there any active development or possibility of ISDB-T modulation? What exactly would need to be done in order to achieve it? It doesn't seem all-too different from DVB-T in t

[Discuss-gnuradio] AM Stereo (C-QUAM) Transmitter.

I have finished work on a CQUAM transmitter in GNURadio. CQUAM was among many competing standards for Stereo AM radio, and is still in use around the world. I didn't see much fo anything online about AM/AM Stereo modulation, so I figured I'd give it a go. Mayb

The file source wouldn't work; I would probably have to use gstreame

[Discuss-gnuradio] Float version of the Frequency Xiating FIR Filter?

I am attempting to translate a 20khz DRM signal from its default spot of 10khz, to 120khz. The Frequency Xiating FIR does this just fine but it also decimates the signal--which I do not want. I want to pass the float input as a float until the final stage at the BlaeRF as my FM transmitter is an al

So here's an interesting one. I need to pipe some samples from a JACK application to my graph. Using ALSA won't work (even with pcm.jack), and I cannot install Pulseaudio in Arch for whatever reason. That was the previous solution, but now it must be JACK. Googling brings up old threads and not mu
