  • v1.212 is out [8 channel mode]

    jksjks
    Obligatory: https://en.wikipedia.org/wiki/No_good_deed_goes_unpunished

    Today's v1.213 update has a "no_wf" URL param, e.g. "my_kiwi:8073/?ext=wspr,40m&mute&no_wf". On an empty RX8WF2 mode Kiwi this would give you rx2 instead of rx0.

    I'm now finding that when a user doesn't get a waterfall, they open more concurrent sessions hoping to find one :-(
    This might be improved somewhat once the audio FFT for channels rx2-rx7 is working.

    So I wonder is there a way of running a second BeagleBone off one set of RX hardware? Sharing the IQ data and GPS etc.
    No.

    Yeah, see that annoys me greatly. I don't want all the Kiwis on the planet to get bricked someday because I'm dead and the certificate has expired. I don't want Kiwis to have some dependency on an external site that keeps them from working. It's bad enough we depend on Google for timezone lookup and various sites for geolocation lookup. There's the proxy and TDoA service issues, but at least they're optional.

  • TDoA doesn't work with a mix of Kiwis using v1.212 and earlier versions

    So this is only an issue when TDoA is done using sampling Kiwis running a mix of v1.212 and earlier versions (e.g. v1.211) That means this problem will get better over the next 24 hours as more Kiwis update to v1.212

    I could add a URL option that implements your second idea. Giving you one of the channels normally handed out to a non-Kiwi UI connection.

    A few notes:
    • It seems to work, but this is a big change. So it is likely there will be some problems. Consider it a beta test.
    • The first time you switch to the 8 channel configuration the TDoA channel limit will still be set at 4 (or less). So re-adjust it accordingly.
    • Having eight simultaneous connections has been tested and seems to work fine. This includes connections via the external kiwirecorder software.
    • It is not clear how well running 8 WSPR extension sessions would fare. There would likely be a serious shortage of Beagle CPU cycles causing the decoding process to run out of time on busy bands. Rob, AI6VN, has already demonstrated a superior solution using a script to connect multiple Kiwi channels via kiwirecorder to separate instances of WSPR-X running on better hardware. The RX8WF2 configuration was developed primarily to make the Kiwi more efficient for Rob's WSPR projects as well as helping to increase the pool of TDoA channels.
    • Speaking of TDoA, we'll probably have to get buy-in from individual Kiwi owner/admins to have them change from RX4WF4 to RX8WF2 mode. Not everyone will want to do this and it probably makes sense to have a mix of configurations available publicly.
    • The audio FFT replacing the waterfall/spectrum will be similar to the existing "audio integration" extension. Essentially a 1024-point FFT on the fixed 12 kHz audio passband.
