  • add DTG to Log

    Hi,

    I'd also like to add the KiWi ID to the time and date, so that it makes it easier to use the data at some later date if a centralised database is ever established.

    Covered in these previous threads.

  • WSPR and who is logged on

    Hi,

    Maybe the user info could be put on the top banner where there seems to be plenty of space.

    The pop out panel which gets hidden by any extensions that are running could then be removed.

    Maybe if multiple extensions are being run they could overlay each other with tabs on the edge ?

  • Direction Finding and linking existing KiwiSDRs

    Hi All,

    I agree even a 100km accuracy would be a good starting point. The advantage of the KiWi network is that it is farily well distributed so once you have a rough location it should be possible to use other KiWi's closer to the suspected location to obtain a more accurate fix. Alternatively lots of fixes could be combined to produce a good average.

    In the UK the radio regulatory body (OFCOM) has a distributed network of 24 remote receiver sites with 20MHz to 3/6GHz DF capability. I believe this uses Keysight / Aligent N6841A units as demo'd in the video linked below.



    Some more background info can be found here


    Some of the research before OFCOM deployed the current network.


    Token - I could add a PPS marker to my KiWi which could be switched in by means of the antenna switch option if this would help with any project. I think Peter, G3PLX, came up with this idea some time ago and I'm keeping him informed about the KiWi enhancements WRT TOA DF'ing as I know this was (and may still be) of interest to the IARU and other National Societies.

  • HF Broadcast Schedules

    Hi,

    Whilst obtaining the data to answer Ron's question regarding DRM broadcasts, it got me thinking.........

    There is a very comprehensive list of HF broadcast schedules listed at http://www.hfcc.org/data/b17/

    I wonder how feasible it would be to parse this and populate a DX.json file (or similar) of broadcast stations from this information ? The DX tags could then change according to time date and BC schedule a bit like the IBP tags.

    The transmission schedules change with seasons, so this could be updated as and when required.
