OpenWebRX directory SDR.hu has now shut down

OpenWebRX was first developed by Andras Retzler and is and open source program that allows users to make RTL-SDRs, KiwiSDRs and other SDRs accessible over the internet via a web browser. Recently the OpenWebRX public directory at SDR.hu, also run by Andras, has been closed. In the past we've posted about Andras' decision to move on from OpenWebRX and how sdr.hu went from public access to requiring an amateur radio callsign to access. Now Andras has decided to take the final step and close sdr.hu for good. The sdr.hu website now reads:

The SDR.hu project has been finished

I'd like to say a big thanks to everyone who joined my journey with this project!

I hope you had a good time listening on the site, and learnt some things about SDR. The purpose of this site was to provide a technological demonstration for amateur radio operators about Software Defined Radio, and I hope this goal has been reached. As this website was a one-person hobby project, with my tasks and responsibilities growing, and my focus moving to other projects at which I hope to make a greater positive impact, I'm unable to further develop SDR.hu and protect it from abuse.

Furthermore, I think this site has some good alternatives now. Nevertheless, in my opinion amateur radio receivers should be shared with strict access control in the future.

If you have more questions, feel free to consult the FAQ.

73!

Andras, HA7ILM

We want to note that although KiwiSDR makes use of OpenWebRX, the KiwiSDR project is not affected by this closure as they use a custom fork of OpenWebRX, and there is an official KiwiSDR directory at kiwisdr.com/public, a map version at map.kiwisdr.com, and an SNR score directory at snr.kiwisdr.com. Unfortunately the one major drawback is that these directories do not list public RTL-SDRs or other SDRs running OpenWebRX as only sdr.hu did that.

Also, although Andras has stopped development on OpenWebRX, a fork of the project led by Jakob Ketterl (DD5JFK) is alive and well at github.com/jketterl/openwebrx and openwebrx.de.

    We can but wish him all of the best in his endeavours, and we can and should thank him for the work he’s done up to now on his projects. I for one am very happy to see that his work has been of use to me through the basis of the KiwiSDR project’s code, and I genuinely wish him all the best with the completion of the PhD. PhDs are not a measure of smartness, but of an ability to persevere through academic adversity, but the feeling of success on the other side should be worth it.

    Those that feel hard done by, by the closure of the service he was providing for free should realise that they should have zero expectation that something provided for free would be free or available forever. If they want to pay for the continuation of the service, I’m sure someone can step up and make a business out of it.

    why is the version on Github so different from KIWISDR versions, is it just because the code acts differently with different hardware ?

    • KiwiSDR

      No. There are pieces of OpenWebRX in the core of KiwiSDR. But everything else developed over the last six years has been purpose-built for the Kiwi. It doesn’t translate back to the RTL-SDR.

    Is it just me or is there something a bit sinister about his comment that “amateur radio receivers should be shared with strict access control in the future”?

      I’ve been looking at SDR myself and I’m busy right now also DMR is also of interest however I’ve shifted from ARES/RACES to studies myself as well my YF Hasher projects as well I’ve decided for now with stepping aside for some time and I’ve been busy where I’ve let go a web site for time restraints nothing sinister ABT it at all I’m also taking psychology courses for Counseling my state mandates BS or MS degree which is another subject.

      I’m not sure why he thinks there should be a restriction, but judging from the FAQ I guess he saw many commercial companies using the public receivers for some purpose. As there’s only limited slots available per receiver, it could make sense to restrict access in some way to prevent hogging.

      • Juan

        I see that could be an issue but his previous move to restrict the directory to radio hams struck me as unfortunate. In any case, I entirely understand him closing a site he has little time to devote to. My ‘sinister’ remark was entirely directed at his mention of access control.

      “Wonder what was real reason”

      Andras is getting his PhD. Do that and you hardly have time to brush your teeth in the morning let alone run a website and deal with all the associated problems.
