  • TDoA maps

    Hi John,

    I like the new TDoA maps in v1.238, I think I actually prefer them to the original :-)

    Thanks for the quick fix.

  • TDoA maps

    Ah yes I missed the other thread, I got confused because I'd been following a similar conversation on another forum regarding the loss of Google maps.

    They had suggested Leaflet (an open-source JavaScript library for mobile-friendly interactive maps) https://leafletjs.com/ as being worth looking at, but I'm sure there are many other contenders too.

    I think this decision may actually cost Google more than they may gain in the long term, and it's not as though they really need the money either.

  • CW (morse) decoder extension in KiwiSDR [added in v1.224]

    Hi John,

    I have a test setup running on http://g8jnj.proxy.kiwisdr.com:8073/ with two AM signals being modulated by a CW recording.

    TEST TEST TEST 1234567890 THE QUICK BROWN FOX JUMPED OVER THE LAZY DOG

    The two signals are at different levels

    3598.00KHz @ S3

    4548.00KHz @ S5

    I can get good decodes (just) on 4548.00 with 50Hz BW and a threshold of 42 but 3598.00 is too weak.

    I'll leave it running so please feel free to use it for your own tests as required.

    Regards,

  • OpenWebRX [using a transverter/down-converter with the Kiwi]

    Hi Lonecrow

    Try http://g8jnj.proxy.kiwisdr.com:8073/

    It's a very quick and nasty lashup which is lying on the floor of my workshop so there is a lot more unwanted noise and hash than there should be.

    VHF 144MHz band antenna, 100m of coax to workshop, 20dB low noise preamp, VHF BPF filter (6dB loss) , 10dB preamp, FM BC Band notch, 10dB preamp, Mini-Circuits Mixer, 115MHz LO injection from a signal generator, 40MHz LPF & into the KiWi.

    I've edited a few DX labels with local airports, but I've not done anything fancy with removing or editing the HF Band markers etc.

    Best performance is between about 120-130MHz as I had to quickly build a band pass filter to remove the FM Broadcast Band and it's not very good.

    I'll leave it running for a few days until I need it for something else.

    Have fun,

  • Ability to re-plot without capturing new I/Q files [added in v1.222]

    Thanks John,

    That makes a huge difference to the speed and ease of use of the TDoA function.

    Much appreciated.
