    Default Realtek RTL2832 E4000 USB TV Tuner

    Hey Mike-
    I came across an article back in June on using certain cheap Realtek RTL2832U based USB TV tuners function as general purpose software defined radio (SDR) receivers. Here are some of the features:
    - Frequency range : 64 - 1700 MHz (50 - 2200 MHz also possible)
    - Sample rate: 3.2 MS/s
    - Resolution: 8 bits/sample
    - < 4 dB noise figure1
    - Software support: GNU Radio, Winrad, HDSDR, SDR# etc.
    - Receivers implemented: AM/FM, GSM, P25, ADS-B, TETRA, GMR, GPS, etc.

    I use SDR# which gives me Wide and Narrow FM filtering and its completely adjustable. I can decode 137 MHZ weather satellite imagery, 2 meter APRS with an AFSK 1200 decoder, can do NOAA Weather Radio DXing just to name a few things with mine and I have barely scratched the surface. I recommend looking at http://sdr.osmocom.org/trac/wiki/rtl-sdr It will give the particulars on which cards to use and are widely available on Ebay. You can also do a you tube search for RTL-SDR and there are some great videos on the capability of the cards. Lastly take a look at SDR# its the powerful free piece of software I use the addresshttp://sdrsharp.com/ They just added RDS decoding with the latest software build. At $20 you cant go wrong.

    Well I just bought one today on eBay. It cost $24.99 and supposedly ships from San Diego.

    I've been to the SDR# website and there's a link there to a quickstart guide somebody made that should be get it running smoothly.

    I know this is becoming quite popular in Europe and you're the first person on this side that I know who has one and has it running. Therefore, if I run into any snags with it, you know who I'm going to be running to for help :-)

    How are you connecting an antenna to it? Many of these units on ebay look like they are using an aerial plug. I also found a listing that mentions 75 ohm input impedance so an aerial plug to F connector adapter should allow me to hook up any antenna with coax cable without impedance issues.

    Got one of these from China for $16 (and a 3-week wait). Not having much luck with the software getting it going. The antenna connector on the USB device is hopefully going to work with this http://www.pimfg.com/Product-Detail/000-F-MCX. The tiny whip antenna that came with it had the threaded screw in the base part not extending far enough out to attach the whip part !

    I went to Radio Shack and picked up a European TV adapter. I went from PAL To F then with a short jumper went to an F to PL-259 so I could hook up to the array of Antennas here. Does a great job and at less than $7 worth every penny. PJ I need to make a video on how to set up these cards. A lot of folks have problems going into the setup. Give me a few days and let me see what I can put together.

    This is where I got mine http://www.ebay.com/itm/RTL-SDR-FM-D...item27c9c7487e After no luck with HDSDR I tried this http://rtlsdr.org/softwarewindows However, the Zadig version I downloaded is 2.0.1.157 (vs 2.0.1.154), and "show all devices" on it just gives me USB Receiver (Interface 0), USB Receiver (Interface 1), and RTL2832U Picking the first two shows USB ID 046D C51B 00 and 046D C51B 01, while RTL2832U gives 0BDA 2832 The SDRSharp.exe.Config file that I downloaded doesn't contain the remark lines re the RTL device to modify (and pasting it in doesn't seem to work either). BTW, the MCX-to-F adapter arrived and does fit.

    This one is the on I am using... http://www.dealextreme.com/p/mini-dv...r-92096?item=8I ordered it from Hong Kong and it took 3 weeks to get it. There is a new pdf manual that is available that walks you through the install process. Here is the linkhttp://www.atouk.com/wordpress/?p=153 I have it installed on a Windows Vista laptop and works pretty well. I only used Zadig one time, as I usually leave the card in the same USB Port. It took me a few times to get it up and running with Zadig but eventually got it running. It was frustrating at first, but everything worked well after that and had no problems.

    I thought this was going to be easy. Maybe not. Delivery supposedly is Tuesday so we will see.

    Mike, that package is identical to what I had the long wait for to arrive by China post. You will need that MCX-to-F adapter http://www.pimfg.com/Product-Detail/000-F-MCX vs the PAL-to-F adapter that other units require. I played around with the Zadig so much on this Win 7 Aspire 5517 that I crippled my Logitech wireless mouse and had to swap in a Gigaware (2.4-GHz) one from the refurbished Dell D505 XP. I'll try to do the Dongle and SDR# thing on the Dell (had already tried the HDSDR route there). BTW, WZ1V, who has had success, had gotten his from that dealextreme source.
