    I have such a question on the top screen in SDR - max. the visible range is ~~ 2.4 MHz. Whether and how to extend it to e.g. 10 MHz or more?

    BW = 3.2 MHz is the maximum for this receiver.

    lysy1980 everything is nice, beautiful, I think I bought a tuna from you a few days ago, but here the problem from another shelf, namely sdr, is ok, but blazehdtv, mediacenter and other crap do not search for programs for me. The headset is installed correctly, not the ones from Zadig only from Realtek and there is no signal in the dark. Antenna installation OK antenna AT 12 elements and 7m of cable. A normal tv tuner works perfectly while usb-stic lipa :(
    For the sdr program, I use the drivers from zadig and the sdr works correctly, but there is no sensational sensitivity, but that's not the point where I'm tired of dvb-t.

    In order for DVB-T programs to work on the tuner, as already mentioned, the original drivers for the tuner are needed. It does not work on modified drivers. After installing the original drivers, it is possible to pick up even in VLC (this way you can check the correctness of the installed drivers), without the need to install a dedicated program to operate the tuner.
    The answer was already on the forum:

    Check maybe on another USB port [not what you have SDR] install as DVB-T

    I've been reading and my hands are dropping. Just moving the tuner to another slot will not help if you do not uninstall the Lib-USB (Universal Serial Bus devices) -> Bulk-In Interface device drivers.
    How many times can you write the same that DVB-T works after the correct installation of the original drivers. The REALTEK 2832U Device appears under Sound, video and game controllers in the control panel of Device Manager.
    In the attachment screen of the screen with correctly installed driver and receipt in VLC program.

    sb8gapi and ass beaten old man, unfortunately I UNINSTALLED the headset and installed the original ones, even on the fresh win7 system, only the ORIGINAL headsets. I have the same as you on the screen and VLC is silent, Miedacenter too and blaze too :( . The tuner cannot be damaged because the 2m amateur radios are played on the sdr and Gli ....... e, turn and 70 cm, which you would not wish for, so it's OK. However, DVB-T is not chula :( on the original driver. Unless you have some magic :) RTL-SDR - an SDR receiver from a cheap DVB-T tuner on a USB connector

    Phonemen, you can write what tuner do you have? Do you have like mine in the control panel?
    Did you uninstall the driver from Device Manager?

    I am sending drivers from my tuner in the attachment, they may work.

    If everything is OK with the antenna, then in the VLC field, in the Transponder / multiplex frequency field, you enter the frequency of one of the multiplexes in your area in kHz (I have one of them at 650MHz, so I entered 650,000 kHz).

    I saw your screen. It looks ok.
    Phonemen and you have the option to check the tuner if it is receiving DVB-T on another computer?

    @phonemen What antenna do you use to listen on SDR ??? Some self-made or factory ??

    sb8gapi You are as big as my little Son would say :) I recommend this reading to all those who struggle with tunkami for a few days and a friend of bald1980 should add the reins of the above post to his colleague sb8gapi by sending an email. I successfully removed the bulk and installed these drivere and "bulka tv nice" :) GREETINGS and have a nice egg.

    Ps. The controls are not equal :)

    Added after 3 [minutes]:

    Jezzman I use scrap metal :) that is, an open dipole on the balcony 1p and a yagi AT 12 is an ordinary tv directional antenna, as if walking in the 400-800 mhz band, but it is enough, but I will create something on the roof, i.e. some omnidirectional only a matter of kasiorki :) to the 10th hoho :)

    I am glad that we have succeeded. Maybe the drivers will still be useful to someone.

    At the beginning, I fought with various drivers for the LV5TDLX, because the tuner program did not search for programs after the drivers from the disc, but this is a different story and the topic is described in detail on the electrode.
    I recommend that you uninstall the drivers in the Control Panel in Device Manager, which will avoid many problems with installing DVB-T and SDR drivers.
    best regards

    @phonemen Do you have a lot of this wire ?? :D I gave some 2m of wire for the window and I do not collect too much from the 2m and 70cm band; / And I live on the ground floor, the antenna on the roof is not for me because the building is a monument and they do not allow ... Personally, I use Not only TV and everything works as if someone wanted it, I can put the original drivers for DVB-T :D

    Jezzman Thanks for the controls, but we've all got it working here :) a few posts higher, as for the antenna, it is half a wave, but it is enough for me locally, i.e. 1 m radiator and 1 m counterweight
    for yourself you have to look for yourself in another section, surely the SP and SQ guys will help, or as I have been playing it for over a dozen years, I recommend a nice ABC knig. likes :)
    Greetings and run away with Mały on the bike and thank SB8GAPI for help

    Well, I was away for Christmas and so much has happened here. As for the controls, the tuners on Allegro, I attach those that I got from the "Chinese" Win7 x64, Vista and XP work OK for me, so I did not look for a hole in the whole and sent those that worked for me. Exactly the same drivers you included sb8gapi , I myself added a few pages ago in one of my posts.

    I also improved the package with drivers on Allegro.

    lysy1980 It's nice that everything is straightened as far as the controls are concerned :) but I have one more problem now, rather hardware on my part. Namely, I have a problem with Lapek, it's just don't laugh please :P Dell Latitude D610 on board has a Pentium M 1.87 GHz and 1 Gb Ramu slingshot, with memory is cool, but the proc gets in Du.e as in the attached screen and cuts the sound on listening and sometimes some correspondence is in she did not fully understand and here the question passes whether to throw the paw into scrap? what I would not like, of course, I cannot afford a new one and it is not going to expand it very much, are there any support programs or some other program checked for listening except hdsdr because this thing is deaf for me. I am asking for some advice and greetings, rubber ears :)

    No wonder it cuts the sound as there is CPU load at 100%.
    I suggest lowering the Sample Rate in Configure to 2048 MSPS or less even to 1024 MSPS.
    Alternatively, download an older version of SDR Sharp from the forum:
    https://www.elektroda.pl/rtvforum/download.php?id=565446 (version 1173)
    or the Stable 1.0 version from the Aurora website
    http://sdrsharp.com/downloads/sdr-stable.zip (has a lower CPU load than the latest version).
    For HD SDR, you need ExtIO_RTL.dll (ExtIO_RTL2832.dll). One of them should be copied to the HDSDR folder.
    The latest version of HD SDR and ExtIO_RTL.dll and ExtIO_RTL2832.dll from February 4, 2014 in the attachment.

    The Sample Rate is one thing, the other is the FFT Display tab to reduce the Resolution to some 8192 or how it will take 16384. The version does not matter, I had and the old and the new there was no difference, although I would be inclined to the newer one. The load is influenced by the type of modulation currently used. WFM is more demanding than NFM.

    the same version, or rather the newest one, is best for all of them. I reduced it to 1024 MSPS and it is a bit better, but it tears a little, which will give Resolution, unfortunately, it did not do anything :( I'm running out of ideas.

    You can also disable unnecessary processes in the Task (process) manager.
    How does HD SDR work?

    sb8gapi hdsdr sucks, the processes are broken, but I cut a few more things with the test method and I downloaded the graphs with these sliders and it's better, it only cuts a bit :) I'm just listening to a repeater at 145,675 some 35km away from my qth. maybe I will improve something else, I hope :)

    Still, disabling the audio filter should help. Audio -> Filter Audio.

    Yesterday I had a moment of slack and I made a converter for the TA7358 and played a little with the KF reception and I will say that it even gives "this" advice, although compared to the TS-850S equipment, it is not fancy, but for a few zlotys you can have fun.
    I do not currently have a dedicated HF antenna and I used the SIRIO GP3-E because I have one on the roof and the reception today was not bad.

    I use SDR RADIO PRO v2.2 connected with HAM Radio DeLuxe which in version 5.xx was free. SDR Radio and HRD work together fully and you can tune the tuner using HRD to the desired frequency, as well as change the filter width, AGC speed and many other functions.
    By the way, I decoded BPSK using the Digital Master which is part of HRD.

    In the screenshots, cooperation between SDR CONSOLE and SDR SERVER via LAN. The receiver is currently on the first floor, and I was sitting on the ground floor.

    What antenna did my colleague use to receive HF ?? A colleague would put in a schematic of this converter here, I would like to make it myself, but I can't find a schematic :(

    I'm starting to play with SDR. A very interesting case :P
    Can someone explain the differences between: "quadrature sampling" and "direct sampling" (I and Q branch) from the technical point of view?

    I have this tuner and a question from a different barrel. I did not find any information in this thread so I prefer to ask here.

    How does the reception "quality" compare to the bandwidth you set? Does it affect the sensitivity, noise or only the load on the computer and the available bandwidth?

    Do you also have strong FM stations around 26 - 40MHz? I even pick them up in stereo and with RDS. The antenna is a piece of cable, but it is annoying to receive harmonics from some other signals.
