Hello I unstalled the packaged for openwebrx but not able to start them....

 

systemctl start openwebrx.service
does not start openwebrx and after a while bails out with : Job for openwebrx.service canceled.

 

Running openwebrx from command line:

Any ideas ?

The OpenWebRX Android Client v1.9 is now available from Google Play. This release adds configurable panel and waterfall colors, KiwiSDR bookmarks and bands display, and a few fixes.

If you like this Android app, please, consider rating the app on Google Play. Every positive voice helps raising app's visibility in the marketplace.

 

Enter URL in the address bar. It keeps history of URLs and will remembdr it.

Is there a way to connect it to our personnal OpenWebRX+ ? Like adding a standalone device ?

Hi Martin, We are working on a newer version which will hopefully solve this problem. Also we will do away with the installer, so you'll just copy the new files over. It should be ready soon. 73

There is no API to retrieve receivers at this point, but receiverbook is open source, so you are free to submit a pull request.

The OpenWebRX Android Client v1.8.1 is now available from Google Play. The new version can connect to KiwiSDR and Web888 servers now. Also, a few bugs have been fixed. If you like OpenWebRX Android Client, please, consider submitting it to RTLSDR Blog, SWLing Blog, and other related websites and YouTube channels.

A vote from me too for such a feature, please! Being able to define (and edit / hack) a list of user preferred BW somewhere would be good; then being able to select between these BW somehow; and having them stored (with mode) as part of any bookmarks defined.

 

Some versions ago, I did figure out how to hack the code to change default BW for various modes, but this hack stopped working when the feature to drag the filter edges about was introduced. Like Martin, I have the 'asymmetrical filter edges' issue here. Assume it's a bug - a minor one - that will be addressed at some convenient time by the developer.

 

Notwithstanding the above, my thanks to the developer(s) for a great system:-)

 

Regards,

 

Mark, G4FPH.

 

This is answered in the FAQ.

Hello. Jakob, this one is mainly for you, as the maintainer of Receiverbook.

I run dxcontest.org, a free DX cluster site for radio amateurs. Next to every
spot there is a "WebSDR" button that opens the spotted frequency on a remote
receiver that actually covers it. We do not proxy or re-stream anything: the
button opens the receiver's own page in a new tab, already tuned to the
frequency and mode, so the receiver gets a normal visitor and the credit.

The list behind that button holds about 880 receivers today. Almost all of them
are KiwiSDRs, which John Seamons (ZL4VO/KF6VO) kindly allowed us to download
once per hour. The OpenWebRX and WebSDR ones we have added one at a time,
taking the bands from each receiver's own status.json or bandinfo.js, which
does not get us very far.

I would like to use the Receiverbook listing for that, and I would rather ask
than crawl the site. The OpenWebRX and WebSDR receivers are the ones we are
missing; we would leave the KiwiSDR entries alone, since we already have that
list. Is there a way you would be comfortable with: a JSON export, an endpoint,
or permission to fetch the listing pages?

Whatever we use, we would download it once per hour at most, from a single IP,
cached on our side; identify ourselves with a clear User-Agent including a
contact address; follow any rate limit or format you prefer and stop at once if
you ask us to; and credit Receiverbook as the source, with a link, both on the
page and in the list itself.

If the answer is no, that is fine and we will leave it alone.

73, Pascual - EA5WU

I just installed toolbox on another of my OWR+ systems.

 

I used /install.sh --public but I still don't see  admin, open Toolbox → Settings → Extras → Public / shared 

 

Also the toolbox panel pops up on opening OWR+, despite this not being ticked as an option.

 

Additionally, it looks like the public still have access to all of the toolbox controls in the panel.

 

Regards,

 

Martin

No need to worry about "it" phoning home.
