I'm using a Khadas vim2 SBC with amlogic S912 processor with docker.

Contrary to tests made with my main computer ubuntu 19.10 x86_64 docker, on the SBC I got no sound whatever modulation I chose, whereas everything seems to be ok (no errors).

The only thing strange is in status, CPU usage stays at 0%.

Both PC and SBC are on the same local lan.

Here is my logs from openwebrx docker container:

when there is only one service on an sdr, the resampling correctly determines that the correct approach would be to not resample. it still sets up a resampler (because the code does not take that edge case into account) and then fails to set up the service for unknown reason.

I just noticed, there is pretty irritating high pitch noise (exactly 12000Hz according to app on phone). Changing volume using OpenWebRX volume slider makes it quieter and louder, so it makes it clear culprit.

Checked on 2cfeb6b, Win 10, Firefox 70.0.1, more than stereo speaker system (Audio output is around 192ksps).

Steps to reproduce:

• load page with default source
• change freq by clicking on waterfall
• change source
• change freq again

At this point traceback is seen in console, and source can no longer be changed.
Reloading page brings some broken state, cannot be used anymore.

I'm using a khadas vim2 SBC with aarch64 processor.

Do you plan to make a suitable docker image for it ?

I would like to see a gain control in the Web GUI so I can adjust the gain of the SDRPlay on the fly.

I know I should open another issue, but this is somewhat related. I would also like to see the max/min waterfall controls automatically adjusted to provide a reasonable display. When I switch bands, I have to change the waterfall sliders. The sliders are very touchy, too.

Thanks for keeping the project alive.

after I change band from browser some times( maybe so frequently or so fast ), the system crash:

as reported in #50: setting the gain on an airspyhf device does not seem to have any effect. needs investigation.

I noticed that the readme contains a changelog that was last updated in November – have all updates since then been bug fixes, or have there been new features rolled out? Any plans for creating a separate changelog?

The newer sdrplay devices (RSPDx) are only supported from version 3 and up. Also, version 3 is supposed to be working on alpine.

Hello

I am using your newest RPi image from 20.02.2020 on a RPi 4, and I am very happy with it.
It would be useful, if the stock network configs could be set up in a way, that if there is no connection over eth0, raspbian would automatically connect via wlan0 with the credentials located in a wpa_supplicants.conf file in the boot folder.
When I try to boot first with a wpa_supplicants.conf file already in place, the RPi does connect to the Wifi, but openwebrx can't be accessed in the web browser and ssh does not work too.

Wifi connectivity can be very useful on field days, where you could create a small wifi network on a battery powered travel router or to increase flexibility in shacks without ethernet.

Hi,

I have a problem with Android and the server, if I am using the tablet or smartphone then I have no demodulation, with the PC no problem. I use Chrome and Firefox as browsers, both with the same error. I attached the terminal issue.

I tried using the image (2020-01-04) with an sdrplay rsp1 , but is keeps crashing/locking up. sometimes it runs a few minutes, but when changing anything it locks up totally.
Maybe a driver problem ?

Attached an Airspy HF + Discovery, and it runs fine for days now
(except the gain setting, but that already is a known issue afiak)

Using an openwebrx as sample source for a CW Skimmer would be a nice to have.
CW Skimmer gets its samples via audio interface (max. 192kSpl/s IQ) or via network interface (i never used it). A background IQ service on the openwebrx server could deliver samples via loopback audio (possibly network is easier?). Furthermore the center frequency of the skimmer needs to be set via a telnet connection (or somehow read by skimmer via a CAT control).
BTW: there is also an open source bayesian statistics CW decoder by AG1LE but unfortunately it it has no CW signal detection that could start the decoder on each signal it finds in a given spectrum. Make a cwskimmer like application would certainly be a separate project.

On an Odroid XU4 with just a simple output device, starting direwolf twice for two openwebrx clients will result in a failure as the default audio output device cannot be opened twice. There is a simple fix to this: Just tell direwolf to use the "null" output device.

(Sorry that this is not a nice pull request, but its just one line to change anyway...)

When the connection limit is reached, openwebrx disconnects the client without any special message. The client responds to this with an automatic reconnect after a 1s delay. This is an endless loop until something else breaks.

The server should send an appropriate error to the client, which should then stop the reconnections, or at least enter the exponential back-off until a connection is available.

I've only seen this in conjunction with #19 so it needs to be tested if this is an actual issue.

Sadly, I had everything working yesterday and now am stuck with these errors when accessing via browser. I appreciate any help you may be able to give.

Hi, got an issue with FM Demodulation, all other Modes work fine:

Is it possible to connect openwebrx to plutosdr with SoapyRemote?

I have installed openwebrx on raspberry pi and I would like to connect it with plutosdr in SoapyRemote mode via tcp.

What do you need to enter in /etc/openwebrx/config_webrx.py in the sdrs = {} section?

Can merge the mobile view code ?
such as : https://github.com/bclswl0827/webrx4mobile

Hello!

Love your work!

Is there any way of using direct sampling on the RTL_SDR V3 ?
I tried searching the wiki and docs but could not find this.
In ha7ilm version you could use the rtl_sdr -D option for this.

I've installed your fork of openwebrx to an Ubuntu server with a PlutoSDR. Everything works fine when a single client is connected, but when a second client enters via the web interface, a new sdr source process is spawned, requesting the same resource being used by the first client.
Instead I think just the nc command should be spawned, listening to the existing stream of iq data. At least this is what happens in the original openwebrx and works with multiple clients.

Please find below the log when the second client is being connected:

Just in case someone else stumbles in the issue, as I did

sudo apt-get install python3-pkg-resources

Raspbian uses Python2 as a default, so Python3 and the abpve package must be installed.

Thanks for the good work.

I put the docker file running on a synology nas machine ( cpu is intel atom c2538), so startup the contianer, after a few seconds , it's log get a error: Segmentation fault (core dumped)

Currently running on a Laptop without wsjt-x installed. Activation of services with default list of decoders leads to error message "FileNotFoundError: [Errno 2] No such file or directory: 'jt9': 'jt9'", even though the feature detector correctly detected that wsjt-x is not installed.

when an sdr device fails, connected users potentially enter a reconnect loop; the user interface is pretty much unusable, and other sdr devices that may still be functioning are inaccessible.

ideally, openwebrx would remove failed devices from the profiles dialog. if no devices are left, a message should appear that no sdr devices are availalbe.

also, users that are using an sdr at the moment it fails should receive a message about what happened, informing them to switch to another profile.

Is there a config file option that enable bias-tee on airspy ?

I need this to power the spyverter upconverter.

Hello my Name is Andy,

I don´t have the Digimods on the Website, can you help me what is wrong?
The add-ons are installed.

Andy

Any chance you could come up with a way of attaching permanent labels to specific freqs similar to how kiwi does it. Or differently. Just something to identify known signals? Since you seem to be the only person actively still developing this software?

This is a not an issue, its a feature request.

I think it would be really neat to expose current user settings in URL.
This way, it would be super easy to share link with someone to specific transmission, or even make some bookmarks.

Fragment identifier is a great candidate for such data, as it is not sent to server. Client code can freely read or change it without any interruption.

Just cloned the rep, as I did a few days ago on a Pi.
git clone https://github.com/jketterl/openwebrx/

Got this error:

Any ideas?
Docker version works however I cannot get the rtl_sdr_soapy to work so I would like to be able to run /features to see if it detecs it. SoapyRTLSDR installed and working.

I'm having some difficulty getting it to run under Ubuntu 18 - I installed all dependencies and configured openwebrx correctly for an RSP2Pro... but when I launch the browser interface, it seems like there's no signal information actually being capture (no audio, no waterfall.) I even checked the /features page and everything looks good.

Any advice on how to troubleshoot? I don't see anything in the console log that looks amiss, either.

I decided to take this for a spin with services and ft8.
RPI 3B seems to be underpowered for even one service (ft8, one worker) and client at the same time, as i am getting choppy sound.

Anyway, im seeing this in logs:

Hi Jakob.

If I use DMR and I muted one channel while two stations are talking same time, the muted station is still hearable.

I know you fixed it. But it still happens.

Also maybe widen predefined ranges

#21 already has some information, but since I'd like to introduce this on the soapy_connector, I will probably need to understand some of the modifications mentioned there and implement them, before it can work.

I tried to start with just an SDRPlay RSP1 connected. The WebUI loads, but throws websocket errors. No waterfall is displayed and no profiles can be selected:

apparently openwebrx does not currently work in safari on desktop or ios. since i am unable to reproduce due to missing hardware, i would be thankful for any kind of debugging output from the console.

due to recent changes to websocket url generation (query-parameters are included), the map does not load properly when opened with an appended callsign, e.g. http://sdr2.justjakob.de/map?callsign=DB0ED

when connecting with a 48kHz client (44.1kHz works fine since it is covered by the defaults), audio is incorrectly sampled to 44.1kHz initially. changing the modulation or profile fixes the problem temporarily until the next reload.

both values seem to have lost their function, receiver is always initialized with the center frequency in fm.

these values should also be used when switching profiles.

Is it possible to add a squelch tone or pl tone support for bookmarks so we dont have to manually set the slider every time we switch bookmarks?

On the Raspberry Pi image instructions in the readme, it mentions https://openwebrx:8073/ – I believe that should just be http://.
