Troubleshooting Help • USING MINI DIGITAL TV STICK RTL2832U 820T2 & SDR ON GNRC

Good afternoon everyone.

I write here to see if any of you know that installation errors I may have had to use the r820t2 in gnu radio companion.

I'm trying to make an FM receiver and other analog TV receiver but when running the program does not receive any type of signal and the view errors, I have: not supported devices to pick from. I believe that this is some driver to be installed but I don't know where or how.

The steps that I have followed for installation (Ubuntu 16.04 LTS) have been:

1. Install gnuradio.
2. Install Xenial Xerius specifications (it is supposed to do I need for my version of Ubuntu).
3. Install specifications of gr-osmosdr to enable some features of the chip.

The Stick comes with a CD but i do not know how to install it since, according to the specifications only works for WXP, 2000, Vista, 7 and 8; and it is something that it seems strange to me since I have seen videos where they use this same model of stick to carry out projects in Gnuradio on Ubuntu.

Please, if any of you know that i need to install It would serve as much help as I am a novice programmer and i need to resolve this problem for my project.

Новые спутники — новые баги.

У запущенного в марте метеорологического спутника GOES-17 проблема — инфракрасная камера нового поколения работает только частично из-за того, что плохо охлаждается. И сейчас одна команда инженеров пытается сократить периоды неполной работоспособности, а вторая — установить причину проблемы. Обе задачи важны, потому что анализ телеметрии предшественника, GOES-16, показал, что там тоже есть признаки ненормальной работы системы охлаждения, и, похоже, четвёртое поколение метеорологических спутников GOES столкнулось с системной проблемой: http://amp.gs/7QCX

Мужики, вот в чём вопрос — в разрыв между приёмником с КВ конвертером и антенной поставил фильтр. Фильтр промышленного изготовления от ж/д радиостанции, настроен на 2130 кГц. Так я слушаю желенодорожников.

Если для соединения использовать разъемы будут ли на них потери? Или оставить соединение пайкой? Как лучше?

HAARP over the next few days

Anyone going to try and receive? What is your setup like? I think I'm gonna try whipping up a slinky antenna real quick tonight.

At windows 10 everything works fine, but Win 7 there is no video only sound,. Search for channels works fine. What is quite stange I can make screenshot caputure of current TV stream even with blank screen and screenshots show current TV programs.

How to repair this problem? Is there alternative software for BlazeVideo to watching TV?

Comment on Helium: The SDR Based Cyrptocurrency for IoT by AD5NL

Some of the ideas are interesting, but they do have a bad habit of coming across as get-rich-quick schemes.

Strange signal at 600 Mhz

Has anyone seen a signal like this before? Sounds like morse code but I don't think it is.

Antennas • Re: HF Antenna for balcony

Hi Kenn,

Thank you for yours answer.
I am total beginner in HAM world. So I have no idea what kind of antenna should I bought.

https://www.ebay.com/itm/Mini-Whip-HF-V ... m570.l1313

This one is nice because is so small, but like I said I have no idea if it OK for RTL SDR?

10 kHz to 30 MHz.

How can antenna have so big frequency range?


What about this one?

https://www.ebay.com/itm/Full-Size-G5RV ... 0005.m1851

If I put it on balcony in few layers, because is so long?

Any other antenna suggestion?

Like I said, I am total beginner.

BR Charlie
