Hi all,
I have compiled and installed rtl-sdr on CentOS 6 following instructions.
Everything compiles without errors, but:
- when I run rtl_test I get the following errors:

If I run rtl_tcp I get the following errors when the client tries to

The same client connects without errors to another rtl_tcp instance on a
Windows 7 computer, with the same module.
Any help is greatly appreciated.
Thanks,

I found this program yesterday: https://github.com/gordonjcp/lysdr
It's the GUI part of a minimal HDSDR/SDR# type program but it needs an IQ stream from something. It seems to be mostly intended for use with Softrocks but I wonder if anyone's been able to feed something like the output from rtl_sdr into it? It's got some Python and some C, requires Jackaudio. I was able to build it and run it under OpenBSD 5.2 without much trouble. Only does USB/LSB as written, Googling doesn't find me anything connecting it with any Osmocom stuff. rtl_tcp through Netcat might work better because it seems to want to control the frequencies. I've only got a couple of $20 dongles.

I keep getting the message "rtlsdr_read_reg failed with -7" whenever I
run any of the rtl_ commands.
When I run the command after re-plugging the stick it usually works
(except the lost samples):

But if I run any of the rtl_ commands after breaking any previous
running command I get:

Is there a way to completely reset the driver other than re-plugging
it?
I'm running Gentoo Linux (3.2.1 kernel)
Thanks!

Hi All,
Just been trying to compile rtl-sdr on my Windows7x64; so I have cloned
the trunk repository, download mingw64, download cmake, get libusb-1.0
for windows and get pthreads-win32. After all I have configured cMake
with the parameter show below:

have this:

Someone can help me?
Hi all,
I have built my antenna and now I wont evaluate my work, so, in your opinions can I use the rtl_sdr software to accomplish it? Someone have a suggestion or is it impossible?
Thanks

I am using DVB-T dongle RTLSDR2832U with gnu radio, i have installed all the required files, but when i compile my flowgraph I get an error.
