Question: Why do the Zadig (SDR#) and Realtek DTV drivers conflict with each other? I can't use the dongle as a TV tuner and SDR tuner at the same time.
Document: The remote works and the dongle picked up my TV remotes and other remotes fine. However, using the rtl-sdr library I have to unload the kernel driver that uses the remote so I can't listen to the radio and use the remote at the same time. I will probably get a USB extension cable because the IR sensor is on the top of the dongle and if I am sitting down at or near my computer I have to lift the remote to weird angles.
Got the cheaper version of the RTL-SDR (DVB-T DAB+FM for $10). Hours of learnings for $10 can't go wrong.Heard commercial FM, ADS-B aircraft 1090MHz, and my handheld. Of course it does not have a xmtr function.Quick summary:The dongle receives signals with its A/D converter (RTL2832U) and its tuner (R820T).
You cannot beat this for the money. This is probably the most fun I have had for under $20 in a long time.I live about 60 miles from the metro area and I can receive commercial FM great. On higher frequencies I was able to find some aural feeds from Christian network stations.This unit has the newer 820T tuner and patching my linux box with the newer tuner drivers sure improved my reception. I am just using the included antenna mounted a few feet up on the wall.
For general purpose 30MHz to &#62;1GHZ reception there is a good ref at: http://rtlsdr.org/softwarewindows.a. Install the Zadig driver, if not installed.b. Install the SDRSharp appHelpful hints:A. To test if the RTL-SDR dongle and ADSB is decoding aircraft data use the Telnet application. Telnet has to be loaded into by: Windows 7 ControlPanel&#62;Program&#62;WindowsFeatures&#62; and check Telnet clientB.
This is a great SDR Dongle for the price. Was able to get it working in no time with very little prep work.The setup/use is the same as any RTL2832 device.The big flaw is that the Attennae is pretty much useless and if you want to do anything with this dongle you will need to replace it with a real/better one, or you will just be listening to a bunch of static.
I thought I was golden when it found 31 TV channels - but then realized it had locked on to my Pinnicle ATSC tuner card, not the RTL-SDR/USB device. With the right device selected, no channels found; later I found out it doesn't work in the USA.So, uninstalled all the included software and installed the ZADiag driver (which Windows found on it's own) and SDR# (&#34;SDR Sharp&#34;).
I wanted to try SDR# software defined radio. This came with TV tuner software. I installed the supplied software and nothing worked. The instructions were almost non-existent so that could be part of the problem, but the tuner had presets for every nation on earth EXCEPT the USA! I then tried using it with SDR# and could never get it to be recognized. It was a complete flop, and I would recommend that no one buy this.
I bought this product to give my computer SDR capabilities. I am able to receive signals across the VHF and UHF bands easily. The supplied antenna can locate aircraft 50 miles away on the ADSB band and receive all local FM stations indoors. I also can clearly receive chatter from emergency personnel up to 50 miles away.I also bought a MCX to F connector to link the tuner to a TV antenna.
You can't just cut the antenna down to 2.7 inches though, unless the metal that you used for a mag mount surface is at least 11 x 11 inches.Now I am picking up aircraft that are 55-75 miles away, which is much better than what I was able to accomplish with a custom-built collinear array antenna.Of course the USB dongle works well (very well!) for "plain old" SDR radio too.
This dongle is amazing. i use it for absd plane tracking. added a adapter and 6DB gain antenna, and see planes 75+miles away.i also have used it as a general coverage receiver,  very neat. can't believe the low price......
Answer: Different modes of operatiton: the DTV drivers pick out a DTV channel and decodes that to video and audio as a TV receiver for media player software. The Zadig driver puts the device into a 'special debug' mode to get the two quadrature signals, the I and Q signals, over a frequency range of up to a few megahertz centered on a selected frequency that are needed for SDR programs. These two modes do not 'play nice' with each other and to make them do so would greatly complicate driver design. Neither those who sell the device as a TV receiver nor those who want to use it as an SDR front end have much incentive to do that.With the I and Q quadrature signals, the SDR program can decode not only DTV signals but also AM, FM, SSB, and anything else someone wants to go to the trouble to write a demodulation routine for (like ADS-B or weather satellite or digital modes). I haven't seen any routines for DTV or ATSC demodulation of IQ signals but that is likely because those using the device for SDR have other interests and the compute requirements would be rather high.Keep in mind, too, that the Realtek DTV drivers are proprietary to be provided with the hardware to enable its designed usage. The Zadig drivers are reverse engineered FOSS that use the hardware in ways the device manufacturer never really intended.
