  • Single URL/bookmark can now open multiple windows/tabs

    In v1.83 you can now say, e.g. kiwisdr.local:8073/?ext=wspr,40m&mute&win2&ext=wspr,30m&mute

  • Nice email from a listener

    I received this email just now:

    Good afternoon. I was hoping you could relay a group message to all those currently providing remote access on

    “I would like to extend my deep appreciation to all the remote providers. The service you provide has given me countless hours of enjoyment. Unfortunately, I am not in a position to purchase my own equipment. Possibly, one day in the future.

    The remote providers continue the amateur radio enthusiast’s exemplary commitment to public service.
    Thanks again for providing this wonderful service. The time, not to mention expense, required to provide this service, has not gone unnoticed.”

  • v1.98 changes/improvements [right-click menu]

    The v1.98 release contains:

    Another round of security and memory handling fixes.
    Some fixes that should mostly eliminate the sudden shifting/tearing of the FAX display (this is different from the skew/slant correction adjustment that still needs to be added).
    A new right-click / right-button menu containing items that were only accessible on hard-to-remember keyboard shortcuts (database lookups, passband restore, etc.)
    If you're the Kiwi's admin, a new graphically-assisted way of setting the manual ADC clock calibration if you're not using GPS cal. See config tab of admin page for instructions.

  • ipad iOS bandwidth adjustment [v1.67 touch events added]

    In the v1.67 release I added some touch event support. So now if you zoom in sufficiently you should be able to touch-drag on the passband edges to change the bandwidth. You can also drag across the frequency scale to move the passband smoothly. tapping anywhere will set the frequency. Dragging outside the frequency scale (waterfall, spectrum, etc.) will shift the waterfall.

    It doesn't work perfectly but it's a big improvement. Tested on iPad, iPhone, Android.

  • GPS Admin screen

    v1.60, to be released tomorrow, will fix a GPS bug that I finally understood today. Apparently, since v1.38 the GPS acquisition process has not been restarting after active users disconnect like it's supposed to. That will lead to the situation where the admin GPS page says "acq yes" (instead of "acq paused"), but there is no refresh icon shown in the "acq" column next to an incrementing PRN as is typically the case. The satellites that are already acquired and being tracked will be be fine until they drift out-of-range and are dropped. So eventually the GPS page will show nothing even though new satellites should be getting acquired.

  • dx.json

    This whole thing is hopefully going to be fixed soon..

  • Minimum CW bandwidth needs reducing

    v1.107 will let you reduce it to 4 Hz. At this low of a value the filter skirts aren't so great as a percentage of the passband width. But there is a definite signal-to-noise improvement over the previous 50 Hz minimum, so this was a worthwhile change.

    Remember the shortcut of holding down the shift key and click on the zoom in/out icons (+/- magnifying glasses) to easily change the passband width by +/- 80%.

  • possible feature : TUNING lock

    I agree. It should work like a browser. I'll update the bug list. There was something similar on there before.

    Also already on the list is the idea of having the classic A/B VFO buttons and a "band memory". So when you hop between bands using the select band menu it goes to the last selected frequency in the band instead of the mid-point, which is what it does now.

  • Is there a howto for getting a kiwi on

    What's the error message? Is it from the " registration status" field on the tab of the admin page? Or the "status" field of the DUC section on the network tab?

    Since you're using DUC on, on the tab selection menu at bottom left, do you have "DUC Domain" selected? And does it show ""?

    On the network tab what yes/no answers do you get when you push the "check port open" button?
