    I have a question. Because I have a dvb-t Not only tv lv5tz card. From what I read on the internet, it has a Phillips tuner chipset, and more specifically NXP TDA18271. Is it possible for this card to work with SDR Sharp? I choose all possible options and nothing :( I have installed the manufacturer's drivers. Maybe some other program can handle it. Thank you in advance for your answer :)

    I opened it. On 2 integrated circuits it is written QTT1010 K4894413064111E and on the other AF9015A-N10918-HLM72

    I have one more question. Namely, if I bought something on the realtek system (I do not remember the number), this standard antenna will be good at the beginning, will I have to make / buy an antenna?

    Buddy in the post 860 I gave a link to the page where he writes what you need to have systems except RTL2832 for the tuner to work and receive. Link to the page. http://sdr.osmocom.org/trac/wiki/rtl-sdr
    Obviously the original antenna is not suitable for reception unless you are listening to base stations up to 5 km away. It has all been written many times on this forum, you only need to read the topic carefully from beginning to end.
    From this Not Only Tv series, only the tuner LV5TDLX had RTL and FC0012, FC0013 and E4000 tuners, but I do not recommend them better to buy tuners from NooElec http://www.nooelec.com/store/sdr/sdr-receivers/nesdr-mini- 2-plus.html or its cheaper Chinese counterparts with the R820T2 tuner chip in a blue housing available on the Allegro.

    I am really interested in sdr tx and there are several projects I found on the internet, including mcHF or Red pitaya or HackRF One. I did not find much about them in the electrode, does any of my colleagues know which of the above-mentioned ones is most suitable for shortwave applications, i.e. the construction of sdr rx / tx?
    Sorry for offTop but I didn't know what topic to ask about it.

    For KF, maybe something from YU1LM.

    I don't know if I feel this way to put together something from YU1LM. I am looking for something a bit more put together, something like this has interested me recently:
    http://www.rtl-sdr.com/building-a-ham-tranceiver-with-an-rtl-sdr-raspberry-pi-and-rpitx/
    http://www.rtl-sdr.com/transmitting-fm-am-ssb-sstv-and-fsq-with-just-a-raspberry-pi/
    https://www.kielydile.com/2014/06/13/raspberry-pi-ham-radio-1-wspr/
    Some input filters and an antenna and to start playing with KF and even more and all kinds of emissions are there.
    The most important thing is that the price is affordable and that is probably my main criterion. I'm just interested if any of my colleagues tried to play with raspberry, red pitaya, or hackrf one, and how much is it suitable for everyday use?

    You do not hear because this is how it should be, there is a so-called "repeater" in the program settings. But I recommend that you download the KG-TONE program from the attachments and turn it on. It is better because, in addition to transmitting sound from VAC to loudspeakers, it also shows DCS, CTCSS and DTMF codes from stations.

    @ sq9gk It all depends on what you expect from such equipment. From my point of view, Red Pitaya looks the most attractive because of its capabilities, but its web interface (EEVBlog) may be a problem. As for RB Pi ... well, a good base but for something .... hmmm and this price, and you can always "train" her for some other profession. Just remember that all this magic of SDR ends and also begins when the signal goes to the A / D converter. Then everything (amplifiers, filters, antennas, etc.) is as it was - "analog"!

    As a colleague BOOM I ZONG wrote, you cannot require a scanner from the SDR, which costs a thousand, but you can listen to something, I listen to PKP on 150 MHz, 121 Airport, 149 fire brigade in my area. I use this SDR and I'm happy because it has a scanner. Zodiak is in the directory to install the driver if needed.

    Thanks buddy BOOM I ZONG, which is further confusion and confusion. I cannot afford transcivers for 5 or 50 k PLN, although I really like them :) I know that I will not run away from the analog because it is the charm of this hobby. SDR offers a lot of possibilities when it comes to signal analysis (satellites, and decoding and coding). I would also prefer red pitaya, but I don't understand what you meant when you wrote about problems with its interface?
    Oh, and you, my friend Hajna, I don't understand? It seems to me that even this low-cost "toy" tuner for r820t2 and rtl2832u is worth much more than scanners for even a few thousand.

    I am asking a wiser than me to insert a scanner into this file, because I don't have the strength anymore. I am from Silesia and I ask the moderator not to stress me with writing about the regulations, etc., etc. I just can't make a scanner with this sdr. Thank you for any help.


    Moderated By kriss51.:

    I am also from Silesia, and I can write correctly in Polish. However, when registering on this forum, you must follow the rules. This time I translated from Silesia into Polish :D

    It was about the plugin, because I can't handle it, it's great that you are also from Silesia, so I invite you to visit me in Zabrze.

    But you didn't make the plug for me, and I wanted a scanner in this file because I have a lot of these drivers, but I only want the scanner in this.

    Anyone know where in Warsaw or nearby you can buy an MCX-IEC adapter? Or even better how to do it yourself. My dongle is blue, with "NooElec R820T2 SDR & DVB-T NESDR Mini2" on the housing.

    How to make? Either buy MCX plug + cable + IEC socket, or cut the antenna from the set, (leave the cable with the plug) buy an IEC socket for the RG174 cable and clamp or solder.

    Buying in my case is not that simple, I can't get this adapter anywhere, and I don't really trust various types of auction sites. Cutting the antenna from the set is not an option, the cable that connects the receiver with the antenna is very poorly made and allows a lot of interference. It is interesting that these disturbances are greatest when I listen in on the Windows + SDR # set, and much smaller on the Ubuntu + gqrx set.

    It may be that something is working under Windows that is disturbing you. A very interesting observation.

    The antenna is on a magnetic base. I found that the best reception under Ubuntu is if this stand is placed on some metal surface. The opposite is true for Windows. I have no idea what this may be the result of. In addition, they probably sold me an older version of the dongle, because the housing is supposed to be R820T2, but the software already detects it as R820T. On this antenna from the set I also receive the audio of some channels from the analog UPC cable. I do not know if this is due to the good sensitivity of this device, or rather the "leaky" installation of the cable operator.

    Of course, from a leaky cable installation :|

    I understand well that you mean such an IEC connector?

    For BOOM and ZONK I finally mastered adding plugins, dll applications. the scanner should be copied to the main SDR Sharp directory, while the magician lines to the Plugins directory and of course, open it with a notepad and save the changes, everything works fine, as I dreamed. I tried to write Kriss51 in the language I understood. Thanks to everyone for now, and I attach the PKP file I mean.

    For those interested in the SDR program, I recommend testing the new SDRUNO program. It is less demanding on the processor, perhaps because the "sample rate" is 0.96 Msps and in fact, as in the description on the website, the sound is clean and better than in SDRSharp. http://rtlsdr4everyone.blogspot.com/2016/07/rtl-sdr-with-sdruno-first-steps.html

    The problem may exist if the signal is put on VAC to decode digital modulations in eg DSD. I put the signal on VAC but probably some filters are set and DSD does not decode the signal. I haven't had time to check all the options yet, but maybe someone has solved this problem and will describe the settings. The downside of the program is that you have to reset the sample rate every time you start the program, the program does not remember it after closing it.
