RTL-SDR Error code -3
by Jonathan Rawlinson 30 Oct '13

30 Oct '13

Hello all I am trying to get the python wrapper "pyrtlsdr" working on Windows, it works fine on Linux The dongle works fine in SDR-SHARP.exe It imports correctly but prints the following error when I try to initialize the Dongle: Traceback (most recent call last): File "C:\Users\M0ZJO\Desktop\RA_Astro\FFTPrint Test.py", line 4, in <module> sdr = RtlSdr() File "build\bdist.win32\egg\rtlsdr\rtlsdr.py", line 60, in __init__ % (result, device_index)) IOError: Error code -3 when opening SDR (device index = 0) RTL_FM also returns the same error. Can anyone help? I would be very grateful! Many thanks Jonathan/M0ZJO

rtl_fm.exe issue or an I doing something wrong?
by Chris Hanson 28 Oct '13

28 Oct '13

I just downloaded the RelWithDebInfo precompiled windows software that was posted on Oct 24th. I am using an E4000 dongle which has a PPM of +30. I am trying to listen to 424.175MHz and I'm using this: rtl_fm -p 30 -d 1 -N -o 4 -f 424.175M -s 16k -C|sox -r 16000 -t .raw -e signed-integer -b 16 -c 1 -V1 - -d everything is playing fine. I can hear 424.175MHz. The issue is that I'm hearing another station 50KHz higher on 424.225Mhz in addition to the frequency I want. So it looks as if it's not using a 16Khz filter. Am I doing something wrong or is there an issue with rtl_fm.exe? Thanks Chris

rtl_fm stereo?
by Pete Ashdown 24 Oct '13

24 Oct '13

Tried searching on this and didn't find much. Is rtl_fm stereo capable? When I encode with lame's "-m s" flag the output is at half the sample rate (ie: speeded up). Do I need to feed it double the sample rate, or am I barking up the wrong tree entirely? Thank you.

API for forwarding remote control commands
by Skip Tavakkolian 21 Oct '13

Hi, Since all DVB-T receivers come with an IR remote control, I'm wondering if there is an API that can be used to receive the remote commands? Thanks, -Skip

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.

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

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
