Open WEB RX enhancements

Some interesting enhancements to OpenWeb RX by Jakob, DD5JFK which he seems to have forked from the original work by Andr?s, HA7ILM.

Apart from the addition of wsjt-x based demodulators for FT8, FT4, WSPR, JT65, JT9

He's also added Clientside bookmarks (DX Labels or Tags) which every user can store for themselves in the browser's localStorage.

Interesting stuff.

  • Ha was just running the main version with an RTL dongle thinking "it's a shame this has not been worked on more" (filter widths, connection defaults, spectrum, etc.)
    Yes I know I should learn to code rather than criticise but I'm a wage slave and time is short.
  • Running the PI image here now, very good to play with.
    I'm not entirely sure how we are meant to stop and start the service and or connectors so have been doing a few reboots after changing things.
    It (the browser session) automatically tries to reconnect which is part curse part blessing, I'm used to playing with OpenWebRX, killing it, changing things restarting, refresh browser.
    This has a few more services in the connectors and I'm not 100% sure how to drive it.

    I did have it running on a small i7 passively cooled x86 box but kept hitting issues after changes so went to the PI and had better success apart from the above.

    Thanks for the pointer Martin.

    Nice, but storing your carefully curated tags in browser local storage without automated backup to a file would make me very nervous. Not sure if a browser extension would allow this. I think browser file writes are not allowed due to security constraints. A method to manually copy to the clipboard is mentioned here:

    Although, this is the way the Kiwi "user preferences" feature (unfinished, unreleased) works too..
  • Yeah that was me asking him to do it. Its way better than nothing! Other than the Kiwi we are lucky anyone is developing this.

    Openwebrx needs a lot of love like jks has provided :)
  • Was playing with this again.
    The RTL dongle connector seems to work better than the soapy one.
    I can't work out how to use the gain values for a RSP1A, they seem to be negative values but still I get intermittent overloading when the gain is dropped referencing the waterfall signals.
    The decoders are fun to play with and casually flicking bands in the first 24hrs I was able to RX 103 countries on FT8.
    I need to power down the PI+RSP1A (using POE switch) after about three or four sets of changes, it seems the RSP1A is not fully reset by a PI reboot(?)
    Still want to get it running on the X86 box for wider bandwidth but can't face the dependency hell (trying to keep to Python3).
  • Is the beaglebone not robust enough to handle wsjt-x style decoding? Just curious. I tinkered with gridmapper and ft8 before which was cool but it was on my PC.

    While learning all of this it bothers me when I find signals I can't identify or decode even looking at the waterfall comparisons. Not showing up in any of the databases etc.

    I think you are in the UK.

    Try taking a look at the tags on my main KiWi on the same frequency you can hear, I use them as my logbook and most have descriptions of signals I have heard and managed to ID.

    I'm always looking out for new utility stuff and can highly recommend for European listening, and I'm also sure Chris can recommend at least one other group :-)

    From follow the tweet+link mentioning Amazon "list of Raspberry Pi images" I'm trying the latest one (2020-01-04) and it is much better than the github listed version.

    Obviously I've been spoilt by Kiwi (I keep looking for std features) and am back to fighting the dreaded LAN spurs and gain issues (SDRPlay) but still interesting to see OpenWebRX in another form.
