The decoder is nice to have at a base station or home where you have a good signal. If you’re looking for a small device to listen to NRSC5 broadcasts at home, well, then you’d be better off with a Raspberry Pi board or other small SBC. Synchronized! After your comment, I couldn’t resist though. I can copy the station fine in analog with some static and a custom filter. If you get a block, a sync, or better yet a demodulation of the audio even for a second of a distant station you’re doing it. Total silence? Version 2 used in the DAB+ versions used in Australian and Europe also include Parameter stereo which sends a mono signal along with a PS signal which steers the sound around the sound stage and only 3 kbit/s required. This was just (presuming you have a Ubuntu/Debian variant) making sure all of the -dev packages were loaded, like librtlsdr-dev. I’m not fighting with ppms and guessing on gain anymore, and most everything is coming in from my town. It’s the redundant sidebands that eliminate multipath. The “HD” in HD Radio does not stand for “high definition.” In fact, Ibiquity, the company that developed (and trademarked the name) HD Radio, claims that HD doesn’t stand for anything. [R82XX] PLL not locked! Excuse me, but to me multipath rejection comes from OFDM, using symbols much longer than signals time spread dispersion. HD Radio is a digital broadcast protocol replacement for analogue broadcast FM. Decoding taxi mobile data terminal signals. Listening to HD Radio on an RTL-SDR unlocks another hidden world of listening with these multi-purpose devices. Use rtl-sdr as a high quality entropy source for random number generation.

Software Defined Radio receiver, covering the radio spectrum from 25 to 1800 MHz. I was led to believe the current problem with using SDR# or HDSDR (or a standalone application) to decode HD Radio is that the codec (?) I let my sdr run the night before and was able to detect a few blocks with an indoor telescopic dipole of a station at 60 miles away as the crow flies. Has anyone gotten this to compile under Cygwin x86_64 ? So going to try and move it over to a Pi 3 and see how that fares. The latest version on github compiles and works flawlessly on Windows using MSYS2. When a data (IQ) recording finished the Stop button processing is now always applied, so the console playback is correctly reset. Yes! The first thing to look for if its working is first block @ 18 it takes about 5 seconds mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) Example: You must close the application and reenter the station and settings you want within the Terminal. It is easily recognized by the two rectangular blocks on either side of a broadcast FM station signal on a spectrum analyzer/waterfall display. recovery.

But not just an AM/FM radio - by using the computing power on your desktop you can listen and decode a wide variety of broadcasts. The information is redundant and yes “some” receivers can happily decode HD on a single sideband; I have demonstrated that before on a Sony receiver; it can be done. Windows-compiled binary, 32-bit flavor. The NRSC-5 standard is openly published and anyone can write and distribute a binary that decodes NRSC-5 audio and data. This is a digital FM radio broadcasting signal that can be identified on a RF spectrum as the two solid blocks surrounding a standard wideband FM radio station. avg: 1152.375000, slope: 0.031250, freqerr: -17.717134 One option is to wait the ~20 years until the patents expire (which for HE-AAC should probably be about 7 or 8 years from now). I went into gqrx and tried as hard as I could to get to the center frequency by fixing the ppm. It makes FM radio sound like CD quality, and it makes AM radio go up to FM quality. Airspy R0, R2, Mini, Airspy HF+ and RTL-SDR can be used as a high performance SDR receiver capable of streaming separate chunks of the spectrum to multiple clients over the LAN or the Internet. This is the reason why receivers will mix the digital and analog signal on the main program as the digital error rate rises. fight the power ! I’m pretty new at this and I was wondering if anyone has a step by step procedure to have my RTL-SDR work with sdrsharp. In Australia the main DAB+ transmitters which are a pure COFDM signal are 50 kW effective radiated power vertically polarised to match car antennas and telescopic antenna in portable radios. P1 service mode 25 kbit/s, P2 74 kbit/s, P3 0 kbit/s in the standard hybrid mode You can also subscribe without commenting. Do the two sidebands carry different information? Recently we’ve seen on GitHub the release of NRSC5-DUI, a fork of NRSC5-GUI which was the first fully functional RTL-SDR compatible HD Radio decoder that we posted about back in 2017. SDR-RADIO.com is a Windows console for Software Defined Radio (SDR) receivers and transceivers. Instead of Thanks, I’ve reran rtl_test -p and let it run for awhile, I initially ran it briefly, and it corrected the tuning enough for NFM. Premium Subscriber. Software-Defined Radio (SDR) is a new technology that offers a simple alternative to bulkier analog radio, adding more flexibility, performance and a smaller form factor. I had considered doing this, but it seemed like too much work. You will need a number of Python-related dependencies fulfilled. It offers a command-line interface as well as an API upon which other applications can be built. The decoding can also be performed in real time and examples of that are also on the git readme. Focusing on ready-to-use SDR hardware for listening with Windows we can recommend following tested receivers: (DVB-T/DAB with RTL2832+R820T2). Thanks for the help!

I was getting some kind of key regeneration error from Mediafire. After the make step, use the command “sudo make install”. I parked nrsc5 on that station over night and was able to get a couple of these: First block @ 6 It’s a similar concept to trying to DX with HD lock lights on radios. I was able to lock this morning at 60+ miles with an indoor antenna with no amplifier. Thanks so much for providing the above info! My chromebook running Ubuntu can’t manage it. Sound quality is not impressive, FM sounds better to me, digital audio compression artifacts are pretty obvious, but that’s not surprising taking data rates into account. :refresh SDRs are everywhere nowadays, from your cell phone to your wireless headset and your cable modem. failed to fix header failed to fix header HD stands for nothing. timeout /t 3 /nobreak HDFM is another nice GUI program for HD Radio. He describes what it is and how to listen to it in the video below. Déclinaison vers la radio logicielle Radio logicielle ou SDR (Software Defined Radio) Comme pour une radio classique, on y retrouve les 3 composants fondemmentaux. In the H-SDR implementation, the AM/FM demodulation and the signal processing are performed inside a standalone tuner while all the digital services (for instance, DAB, HD Radio, and others) libraries are executed by a microprocessor. The specification does not (sadly) include a description of the iBiquity HDC codec. I almost have this working per your description above. Au Radio-Club de Perpignan, Daniel F1UCG nous présente “SDR-Consol”, un logiciel SDR conçu pour les communautés commerciales, gouvernementales, radio amateurs et écouteurs. Cheers! Sounds sort of cool in a geeky kind of way but it wouldn’t be very practical. There’s also a very nice GUI for both Windows and Linux builds. These digital stations deliver crystal clear audio without the static of an analog station with multiplexing. Take SDR Touch anywhere and find out what hides in the radio spectrum! avg: 1200.250000, slope: -34.500000, freqerr: 50.750717 The answer depends on many factors amongst application, environment, antenna and price. Those messages are informational and describe the sampling offset error and frequency error. on lower signal it may find a block synchronize then become unsynchronized on lower signal you wont see anything just the avg: stuff I havent worked out the gain to get the lower signals working very well yet A simple crystal-controlled SDR like the Softrock Lite may be connected to the IF of a conventional receiver or transceiver to give a panoramic SDR display and all the other features of SDR. BER: 0.161592, avg: 0.161592, min: 0.161592, max: 0.161592 That value is critical. HD Radio is a proprietary digital radio modulation primarily used in North America.
