Problems on CentOS 6 64 bit

13 Oct '13

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: Found 1 device(s): 0: ezcap USB 2.0 DVB-T/DAB/FM dongle Using device 0: ezcap USB 2.0 DVB-T/DAB/FM dongle Found Rafael Micro R820T tuner Supported gain values (29): 0.0 0.9 1.4 2.7 3.7 7.7 8.7 12.5 14.4 15.7 16.6 19.7 20.7 22.9 25.4 28.0 29.7 32.8 33.8 36.4 37.2 38.6 40.2 42.1 43.4 43.9 44.5 48.0 49.6 Info: This tool will continuously read from the device, and report if samples get lost.

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, Dan

rtl_sdr and lysdr?
by Alan Corey 11 Oct '13

11 Oct '13

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. ----- Radio Astronomy - the ultimate DX

rtlsdr_read_reg failed with -7
by Petter Gustad 11 Oct '13

11 Oct '13

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): rtl_test Found 1 device(s): 0: ezcap USB 2.0 DVB-T/DAB/FM dongle Using device 0: ezcap USB 2.0 DVB-T/DAB/FM dongle Found Fitipower FC0013 tuner Supported gain values (23): -9.9 -7.3 -6.5 -6.3 -6.0 -5.8 -5.4 5.8 6.1 6.3 6.5 6.7 6.8 7.0 7.1 17.9 18.1 18.2 18.4 18.6 18.8 19.1 19.7 Info: This tool will continuously read from the device, and report if samples get lost. If you observe no further output, everything is fine. Reading samples in async mode... lost at least 84 bytes But if I run any of the rtl_ commands after breaking any previous running command I get: rtl_test Found 1 device(s): 0: ezcap USB 2.0 DVB-T/DAB/FM dongle Using device 0: ezcap USB 2.0 DVB-T/DAB/FM dongle rtlsdr_read_reg failed with -7 rtlsdr_write_reg failed with -7 rtlsdr_read_reg failed with -7 rtlsdr_write_reg failed with -7 rtlsdr_read_reg failed with -7 rtlsdr_write_reg failed with -7 Is there a way to completely reset the driver other than re-plugging it? I'm running Gentoo Linux (3.2.1 kernel) Thanks! //Petter

Can I use rtl_sdr to evaluate my antenna?
by Alessandro Staniscia 09 Oct '13

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

rtl_? for radio control?
by Alan Corey 27 Sep '13

27 Sep '13

OK, so you plug a $20 dongle into a Raspberry Pi, hook some stuff to the GPIO connector and with probably minor tweaks to something like RTL_FM you can use it as a radio in radio-controlled model planes, cars, boats. Add the Pi's $25 camera and you could have a radio-controlled camera, useful for sending up in a radio-controlled plane or doing wildlife photography. If you've got some analog (pulse position) channels those would be good for rudder, flaps, various camera settings. This can be done in the 27 MHz CB band or with a ham license in something like the 6 meter ham band. I had no trouble getting RTL_FM running on my Pi but it probably doesn't have enough CPU horsepower to do a lot of processing on the dongle side and on the imaging side at the same time. Anybody done this? Alan ----- Radio Astronomy - the ultimate DX
