Osmo-FL2K stops transmitting randomly

by Sajjad Golchin poor

Hi all, as some of you know Osmo-fl2k has a bothersome software issue that sometimes just stop transmitting without any good reason. in my case when I was transmitting WBFM sometimes it may stop transmitting. I mean the RF output will be interrupted completely without any error or warnings on screen and I should re-execute the commands to transmit again and this goes on and on. sometimes it may work without any issues for like 10 min and sometimes it may fail after just a few seconds. the problem also appeared in executing <fl2k_file> when I was transmitting DVB-T. you can watch this video to gain a better understanding: https://www.youtube.com/watch?v=G0tjzPHFFA8 I have no idea if this issue been discussed earlier in the mailing list or not, anyway I didn't find anything useful by Googling.your comments and suggestions are greatly appreciated. Regards,Sajjad

Osmo-fl2k

by Fred Neich

Hello, I have a question about osmo-fl2k, the generated binary file using the fl2k grc transmission flow graphs, contains the carrier frequency, the fl2k_file stream the file to the device, so how the device can transmit these data in that frequency. I mean how it recognize the frequency to transmit on. Thank you.

Tagging new versions of rtl-sdr and osmo-fl2k

by Harald Welte

Hi! Today I've added rtl-sdr and osmo-fl2k to the automatic nightly package builds at https://build.opensuse.org/project/monitor/network:osmocom:nightly I also wanted to add them to the "latest" feeds (which build that latest tagged version, as opposed to a nightly snapshot). However, for this to work we need tagged versions that include the "debian" sub-directory in the respective projects. I hence temporarily disabled the "latest" builds until that happens, see https://build.opensuse.org/project/monitor/network:osmocom:nightly Please let me know once new versions are tagged and the above patch can be reverted.

Request for help with MxL608 tuner driver (Tzumi MagicTV etc)

by James Dallas

Hi everyone, There has been a considerable discussion in the past couple of days about a device called the Tzumi MagicTV. This is an Atheros-chipset OpenWRT device connected to an RTL2832P, which seems to be used as a bridge/DAC for a MaxLinear MxL608 tuner and a Panasonic ATSC demodulator. The device is sold at Wal-Mart stores for $13, and is intended to allow the user to view OTA broadcasts using a WiFi connection to the device, which functions as an access point by default. There also seems to be an Eardatek Tevemo device which is similar. >From tear-down inspection as well as poking around the file system, some uses have concluded that the device could be used as a software defined radio with some software modifications (for example replacing the default ATSC server software with rtl_tcp). However, librtlsdr does not currently support the MxL608 tuner, and right now rtl_tcp (when placed on the openWRT device) defaults to direct sampling mode. There is a general sense in these discussion groups that MaxLinear's source code could be ported to work with librtlsdr, but someone would have to make that happen. I am sending this message to the group, to reach out with a humble request/suggest/beg that someone(s) please help us out by doing the following: 1. Sanity-check the claims being made; if what is being discussed is not workable, it would be of benefit for us to be told so. 2. Start work on forking librtlsdr and porting the MxL608 driver over (if possible/practical); 3. Coordinate with the broader community to beta-test and refine // help spread the knowledge so that the community can maintain/improve the fork and perhaps submit a pull-request in the future. Please let me know if I can help you help us by procuring/shipping a couple of hardware units for development purposes. I understand that asking people to do volunteer work can be presumptuous/annoying. All I can say in my defense is that there are already at least a few dozen people who would be really happy and appreciative if this came to fruition, and "one does not get what one does not ask for." Moreover, adding MxL608 support to librtlsdr might help broaden the hobby to include a whole bunch of other devices; MaxLinear tuners seem to be used a lot with set-top gear. Thank you very much, James "Gwen" Dallas, AD5NL Reddit user: texasyojimbo Phone: 1-713-254-4175 P.S. here are the existing discussion threads for reference: 1. RTL-SDR.com blog: https://www.rtl-sdr.com/tzumi-magictv-wifi-tv-tuner-device-contains-an-rtl-… 2. Reddit RTLSDR group: https://www.reddit.com/r/RTLSDR/comments/8mlbps/tzumi_magictv_is_an_openwrt… P.P.S here is a link to the existing MxL608 driver source code: https://github.com/avlogic/AVL6862/tree/master/2.10.7/tuner/MxL608 and data sheet: https://datasheet.lcsc.com/szlcsc/MXL608-AG-T_C141783.pdf

Is it possible to provide a compressed file for every git tag?

by Filipe Laíns

Hi, I am packaging some of your software for Arch Linux. For that, I need to fetch the source tree I want to build. The problem is that there's no need to fetch the whole git repository to build a specific tag. As a solution, I propose that compressed files from every tag would be available, like GitHub releases. Please let me know if this is something you would consider doing. Thanks, Filipe Laíns (FFY00) https://github.com/FFY00 3DCE 51D6 0930 EBA4 7858 BA41 46F6 33CB B0EB 4BF2 Sent via Migadu.com, world's easiest email hosting

RTLSDR Dongle Getting very hot even with out use.

by Bill Gaylord

I am having this problem with all of my dongles (from multiple sources) and was wondering if it could be some sort of problem with it not getting closed properly, In all cases the chip that gets hot is the actual SDR not the tuner. But I don’t understand why it is heating up when the dongle is not in use and is just plugged in. Or is this just some weird problem with the dongles. Sincerely, William

RTL-SDR Continuous Operation

by loay abdelrazek

Hello, would like to know, what is the average time that an RTL-SDR (R820T2) can run nonstop without affecting its internals The use case, is to sniff GSM packets noting that sniffing will take several intervals during the day, and the experiment should only run for 1 day , thus what could be the appropriate interval thanks

R820T Loop Through

by Carl Laufer

Is there any reason for this to be turned on during normal operation of the RTL-SDR? Turning it off seems to reduce current usage by 10 to 20 mA. To turn it off set reg 0x05 bit 7 to 1. Seems to turned be on by default. Haven't seen any effects from turning it off.

[PATCH] Fix rtl_adsb hanging upon a signal in Fedora 27

by Pete Zaitcev

This code stayed unchanged for many years, but for some reason rtl_adsb started hanging upon exit: *b66116a5164b69281eacc42ae950; ^CSignal caught, exiting! <------ hangs here forever Examining it with gdb reveals that the demod thread waits peacefully on the condition variable, which we're trying to destroy. Either the signals killed all threads before, or condition variables were possible to destroy while other threads still waited on them. The easiest fix appears to be just cancel the demod thread and wait for it to exit before proceeding for the door. --- src/rtl_adsb.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/rtl_adsb.c b/src/rtl_adsb.c index 07fdd2a..9087de4 100644 --- a/src/rtl_adsb.c +++ b/src/rtl_adsb.c @@ -492,6 +492,8 @@ int main(int argc, char **argv) else { fprintf(stderr, "\nLibrary error %d, exiting...\n", r);} rtlsdr_cancel_async(dev); + pthread_cancel(demod_thread); + pthread_join(demod_thread, NULL); pthread_cond_destroy(&ready); pthread_mutex_destroy(&ready_m);

[osmo-fl2k] Code issues/warnings report

by SDR is cool

Hi everybody, Thank you for developing osmo-fl2k. Just wanted to report some relevant code issues/warnings I've found in osmo-fl2k's codebase: hope you'll find it useful.

Discerning FL2K devices with LDOs versus switching regulators

by Mac A. Cody

Greetings, In Steve Markgraf's slide presentation (http://people.osmocom.org/steve-m/fl2k_slides/osmo-fl2k.html), do slides 16 and 17 imply that some FL2K devices have LDO regulators while other using switching regulators? Obviously, the FL2K devices that have LDO regulators are preferred, due to fewer spurious RF emissions. How can one determine which FL2K devices have LDOs? Can an FL2K device be reworked to use LDO regulators? Thanks, Mac

osmo-fl2k baseband to carrier

by azerty lr

Hello, First thank you for this FL2000 hack, it's very nice! I tried to make an FM & AM transmitter with it and GNU Radio. It's working fine if I save to a file and then use fl2k_file to transmit the data but with the tcp server and fl2k_tcp, my computer is not fast enough to sample in real time at 100 MHz. I also tried with a 35 Mhz sampling rate but it's not real time. Here is the diagram I used. Is there a possibility to avoid sampling at a very fast rate if the data bandwidth is small to do the baseband to carrier shift? [cid:0115622e-668a-46ae-8e49-07a3a7aba391] Thank you, Best regards, Jean-Paul

fl2k: Versioning?

by Müller, Marcus (CEL)

Hi everyone, hi especially Steve, I'm in the process of making a distro package for fl2k for sharing and inclusion in my bootable Fedora sticks; as a version, I'd use 0.0.0.1- githash, but I think that's an understatement, because it looks to me like fl2k was officially released at OsmoCon. Now, I'm not the author, and I'd hate to be the one to define today's git head as version 1, or something like that, but I honestly think that it's worth encouraging tagging of a release (as it would make it easy to refer to things like "hey, that used to work with 1.0.2.1, but broke in 1.0.3.1", or include it with other software etc). Would it be very annoying to kindly request that you add a version tag, and to even brazenly recommend semver.org as versioning scheme? Thanks, and I'm having great fun with this, Marcus

gr-fosphor is choppy at audio frequency

by Ignatius Rivaldi

Hi, I'm (ab)using gr-fosphor for audio spectrum visualization by using float to complex because it is the most colorful spectrum analyzer that I have. Unfortunately, for some reason gr-fosphor is choppy at 48 kHz, while it is smooth at rtl-sdr output, about 2 MSPS or so. Is there any FFT configuration setting like other spectrum analyzer to change how many FFT bins and the framerate?

[PATCH] Make sdrangelove friendly for packaging

by Dave Olsthoorn

This patch makes sdrangelove able to install through 'make install' and also makes the plugin manager able to load from a specific directory like /usr/lib64/sdrangelove/plugins while sdrangelove is inside /usr/bin. To load plugins from a specific directory start cmake with '-DSDRANGELOVE_PLUGIN_DIR:PATH=/path/to/plugin/directory' and compile, to make installing even more easy 'make install' installs the plugins in the specified directory.

fl2k RGB buffer format

by Abhishek Goyal

I am trying to understand the layout of the RGB buffers sent to the fl2k over USB. From lines 755-820 in libosmo-fl2k.c I can see the RGB buffers are "serialized" in this order: g1,r1,b2,g2,b0,g0,r0,b1,b4,g4,r4,b5,r2,b3,g3,r3,r6,b7,g7,r7,g5,r5,b6,g6 (where r0 is the red component of first pixel, b3 is the blue component of fourth pixel, etc) What is this layout? Why does the chip expect the pixels to be sent in this order?

Bug: gr-osmoscom for USRP B210 have this weird center frequency signal while gr-UHD don't

by Ignatius Rivaldi

Hi, At first I reported this bug at Gqrx mailing list: https://groups.google.com/forum/#!topic/gqrx/pVea3JObMLw , then Csete mentioned that Gqrx uses gr-osmosdr source, while I'm using gr-uhd source. Then I tried it again using osmocom source, then that weird center frequency noise appears again. I've attached several screenshots and GRC flowchart that I used to reproduce this bug (it uses gr-fosphor). Maedhros_008.png is the screenshot of gr-fosphor displaying the correct UHD: USRP source, with all of FM broadcast radio visible, while Maedhros_011.png is the gr-fosphor showing the output of osmocom source, with this big ~2MHz spike at center frequency, and all of those FM broadcast radio are not visible. I'm using Arch Linux with gnuradio, gr-fosphor, and gr-osmosdr compiled from source using makepkg/pkgbuild system, and libuhd 3.10.2.0-3

Re: Meaning of rtl_fm output values

by Müller, Marcus (CEL)

Hi Theodric, no, these values that appear on stdout are already audio samples (PCM to be specific). That is the "job" of rtl_fm: It takes the complex time-domain baseband samples from the hardware, detects FM (which implies detecting a frequency deviation) and convert that to audio amplitude values. The `aplay` command barely takes these samples and hands them over to the sound card (after resampling to fit possible sampling rates, I guess, as 120 kHz isn't something that sound systems usually operate at). The `rtl_fm` command takes a couple of parameters. In your case, `-M wbfm` means that it's demodulating FM in a way compatible to broadcast FM; that implies fixed parameters for deviation, emphasis etc. What you want is really not `rtl_fm`, which primarily is a demo program, not meant to be a flexible do-it-all solution. What you want, showing deviation of a station, does very much sound like a spectrum visualization. Wouldn't a waterfall or even just an instantaneous spectrum visualization be what you want?

I got rtl_fm running on my system (cygwin running on Windows 7). It is sending a stream of 16-bit signed integer values to stdout which I can redirect to a file or pipe to an audio playback system, such as sox. So when I do this: rtl_fm -f 88.1M -M wbfm -s 240k -r120k -g 30 | play -t raw -r 120k -b 16 -c 1 -e s -V1 - I hear sweet, sweet music! Hurray! But how do these 16-bit integers relate to the modulation level of the carrier? I'm assuming that the values are directly proportional to the instantaneous frequency deviation of the transmitted signal. Is that right? If so, how do I determine that ratio? I'm hoping to use this to build a device that shows total modulation (as a percentage of the maximum modulation of +/- 75kHz) for an FM radio station. Also, I'm assuming that the sample-rate of the output data stream needs to be at least 120kHz because the baseband signal includes the stereo pilot (19kHz), the stereo subcarrier (38kHz) and an RBDS subcarrier (57 kHz). Any insight would be appreciated. Thanks in advance, Theodric Young

RTL-SDR sample bit depth

by John Ackermann N8UR

Hi -- I'm trying to understand the sampling and decimation structure of the RTL-SDR dongle, to work out the effective number of bits after decimation. From Google and looking at the librtlsdr code (which is beyond my programming depth), I think I've figured out the following. I'd much appreciate verification/correction/amplification. 1. Actual ADC in the RTL-2832U is a single-bit sigma-delta running at some very high rate. 2. This is converted to 28.8 msps at 8 bit depth. 3. 28.8 msps is downsampled to the rate requested by the user and sent over the USB bus as 8 bit unsigned IQ pairs. Based on that, I *think*: a. Any processing gain in the downsample from 28.8 msps/8 bits within the chip is lost because the wire samples are limited to 8 bits. The output is 8 bits dynamic range regardless of the sample rate set. b. THEREFORE... for best dynamic range one wants to set the RTL-2832U to the highest sample rate that avoids lost samples, and do further decimation in the host processor, where the added bits aren't lost on the wire. I'd appreciate any verification or correction of that analysis. Thanks, John

RTL-SDR : No supported tuner found

by Lidoro

Hello, I try to install rtl-sdr and gnuradio on my computer, on Linux mint 18.1 cinnamon 3.2.7 64 bits. the installation is going well but when I try to execute rtl_test : Found 1 device(s): 0: Realtek, RTL2838UHIDIR, SN: 00000001 Using device 0: Generic RTL2832U OEM No supported tuner found Enabled direct sampling mode, input 1 Supported gain values (1): 0.0 Sampling at 2048000 S/s. I try intallling with a script and with pybombs, i have the same issue. My dongle have RTL2832 chip and FC0012 tuner it works on windows, and it works when i use "linux live gnuradio dvd". And it works if I start on "linux live gnuradio dvd" and reboot after on linux mint. Thank you for your help Best Regards Lidoro

rtl-sdr with bias T

by Cinaed Simson

Hi - there appears to be problem with rtl-sdr with bias T and the RTL2832U OEM Rafael Micro R820T tuner. I get PLL errors when I try to calibrate it using kal - or when I use rtl_test. Using device 0: Generic RTL2832U OEM Found Rafael Micro R820T tuner Exact sample rate is: 270833.002142 Hz [R82XX] PLL not locked! Setting gain: 33.8 dB And I get the same error PLL when I run rtl_test. If I back out of the latest git version to v0.5.3 it works correctly - I can calibrate the dongle using kal and run rtl_test without any PLL errors. This is a known problem? -- Cinaed

[PATCH] RTL-SDR: Fix regression in FC00012 tuner startup (needs testing on FC2580)

by David Basden

This patch fixes a regression of rtl-sdr dongles with the FC00012 tuner. The code to switch on the FC00012 tuner by pulling it's ~RESET line low ended up with an off-by-one error in a refactor a long time ago, The FC00012 only continued to work by accident as a different bug in rtlsdr_set_gpio_output had a side-effect of pulling low the FC00012's ~RESET line When the rtl_set_gpio_output bug was fixed in ba64a7459a43 the side- effect also went away, leaving the FC00012 tuner in reset, and failing to be detected (or indeed work at all). This patch fixes the original off-by-one error. It's been tested on an FC00012 in a GTek T803 from both warm and cold starts, but needs testing on the FC2580 as both the FC00012 and FC2580 are brought out of reset by a GPIO off the RTL (at least in some designs). If the FC2580 actually uses a different pin, this code will also break. (I'm only going from vague memory that the FC2580 used the same pin.) --- src/librtlsdr.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/src/librtlsdr.c b/src/librtlsdr.c index b369a5d..678fadd 100644 --- a/src/librtlsdr.c +++ b/src/librtlsdr.c @@ -1565,11 +1565,11 @@ int rtlsdr_open(rtlsdr_dev_t **out_dev, uint32_t index) } /* initialise GPIOs */ - rtlsdr_set_gpio_output(dev, 5); + rtlsdr_set_gpio_output(dev, 4); /* reset tuner before probing */ - rtlsdr_set_gpio_bit(dev, 5, 1); - rtlsdr_set_gpio_bit(dev, 5, 0); + rtlsdr_set_gpio_bit(dev, 4, 1); + rtlsdr_set_gpio_bit(dev, 4, 0); reg = rtlsdr_i2c_read_reg(dev, FC2580_I2C_ADDR, FC2580_CHECK_ADDR); if ((reg & 0x7f) == FC2580_CHECK_VAL) { @@ -1581,7 +1581,7 @@ int rtlsdr_open(rtlsdr_dev_t **out_dev, uint32_t index) reg = rtlsdr_i2c_read_reg(dev, FC0012_I2C_ADDR, FC0012_CHECK_ADDR); if (reg == FC0012_CHECK_VAL) { fprintf(stderr, "Found Fitipower FC0012 tuner\n"); - rtlsdr_set_gpio_output(dev, 6); + rtlsdr_set_gpio_output(dev, 5); dev->tuner_type = RTLSDR_TUNER_FC0012; goto found; } -- 2.13.2

(no subject)

by David Basden

Hi, I recently found my dongle with the FC0012 again after having lost it for a couple of years, and noticed the tuner wasn't detecting on recent builds (by recent, it looks like at least a year and a half ago. :) ) There were a few other posts around that I saw with the same issue so I dug into the problem a bit. It looks it was a behavioural regression in commit ba64a7459a43652354990855176a7d8dad5b9d54 which was a actually bugfix in the GPIO direction setting code (see below for the commit comment). The bugfix patch references http://lea.hamradio.si/~s57uuu/mischam/rtlsdr/ports.html which The reason this regressed the FC0012 tuner support is that in tuner detection code, before the probe for the FC00012 there are a few lines: /* initialise GPIOs */ rtlsdr_set_gpio_output(dev, 5); /* reset tuner before probing */ rtlsdr_set_gpio_bit(dev, 5, 1); rtlsdr_set_gpio_bit(dev, 5, 0); Looking at one of the early (ugly) patches I wrote trying to get the FC0012 working, This is the original code before cleaned up: https://gist.github.com/dbasden/2171926#file-rtlsdr-fc0012-diff-L123 : + if (tuner_type == TUNER_FC0012) { + dump_rtl_regs(); + DEBUGF("reset fs0012 tuner... "); + /* the fs0012 has it's RESET line hooked up to GPIO5 + * + * If we don't set GPIO5 to an output and leave it floating, + * the tuner never comes up (just stays in RESET state) + * + * GPIO6 controls the V/U band filter, so we should set that + * to an output too + */ + r = rtl_read_reg(SYSB, GPD, 1); + r &= (~(0x30)); rtl_write_reg(SYSB, GPO, r, 1); + r = rtl_read_reg(SYSB, GPOE, 1); + r |= 0x30; rtl_write_reg(SYSB, GPOE, r, 1); + + /* Do reset */ + rtl_set_gpio_bit(5,1); + rtl_set_gpio_bit(5,0); + dump_rtl_regs(); + } This code was eventually abstracted out to The bug in the code above described in http://lea.hamradio.si/~s57uuu/mischam/rtlsdr/ports.html, linked to in the commit log of the ba64a7459a43652354990855176a7d8dad5b9d54 fixing the same bug. The code was cleaned up eventually abstracted into rtl_sdr_set_output(), which had the same typo as my original code: I wrote back the GPD register to GPO. This accidentally worked enough to fix the specific case I was wanting (to stop the RESET line of the FC0012 floating), but didn't actually write to the GPIO direction register. Looking at some of the forum posts, and checking myself, if the older code runs once, the tuner will be just fine until the dongle loses power. Then as GPIO5 is not set up into a state for the FC0012 to be happy, it will not come up again. This seems to have made the problem harder to debug (I don't know if I would have not known where to look if I had not already hit the problem when originally porting the driver) Digging through some more just now (I really don't have a great dev environment right now, and nothing to probe the hardware itself easily available), I checked the state of GPD, GPO and GPOE before the tuner probing, at it looks like the only real side effect from the code above being buggy would be to set bit 1<<4 low. calling rtl_set_gpio_bit(4,0) brought up the FC0012 tuner. Re-reading the old and new code, it looks like it's an off-by-one error in GPIO numbering: * The original code set GPOE on 0x30, which is (1<<4) | (1<<5). * These are referred to in the code above as "GPIO5" as the FC0012 RESET line and "GPIO6" as the V/U band filter control. * rtlsdr_set_gpio_output(5) and rtl_set_gpio_bit(5,0) are switching the V/U band filter, not the RESET line for the FC0012 Sorry, I don't have access to the datasheet for the RTL, so I'm not sure if bit 0 is GPIO0 or GPIO1. In any case, it looks like the solution is to just fix the off-by-one error in the FC0012 probe code. I'll post a patch.

Fix for FC0012

by David Basden

Hi, I think my messages are getting filtered, but on the chance that someone is reading these as unmoderated, the fix for the FC0012 is to set GPIO 4 to 0. It could be that GPIO4 is the RST, or that it is something else entirely. Looking through the code, and the state of the registers on startup, one of the surprisingly few side effects of writing GPD to GPO would be to set GPIO4 to 0. Multiple bugs working together made the whole thing work. David

This is as far as I've gotten so far. I don't really have a good setup right now for debugging much further right this moment, but I at least know where the problem is. I don't have a copy of the RTL datasheet, or easy access to anything to measure the levels on that line, but assuming that the bugfix is the correct behaviour, and the buggy code is undefined behaviour, it's quite possible that I've managed to get the GPIO5 into a state just enough to get keep the FC0012 out of reset. Looking at some of the forum posts, and checking myself, if the older code runs once, the tuner will be just fine until the dongle loses power. Then as GPIO5 is not set up into a state for the FC0012 to be happy, it will not come up again. This seems to have made the problem harder to debug (I don't know if I would have not known where to look if I had not already hit the problem when originally porting the driver) Flipping the gpio bits the other direction is not working, so I'm going to have to look at it further, but I figured I should at least post to say where the bug was even if I haven't gotten a solution yet.
