  • Help needed: DSP, SSB, Hilbert transforms, Octave language

    All I got out of that thread was "82 year old codger" and "AI hallucinations", both of which I can relate to (lol).

    Actually I think I know what the problem is (amplitude imbalance). But I can't test until tomorrow.

  • Bad drift but ALL 12 CHANNELS GPS GOOD [check "Acquire if Kiwi busy?" checkbox]

    He mentioned in his email to me (but not in the post above) that it was set in continuous mode.

    Hi Ron. I think you must have checked "acquire if busy" because I now see "GPS acq yes" in the user control panel "Stat" tab with 3 users connected.

    One better way to assess frequency cal / drift than simply using zoom level 14 is to use the WSPR extension since it has an FFT display that has very good resolution. In the screenshot below I have set it to run on 30m. But tuned to a dial frequency of 14999.25 so that the time station carrier is in the middle of the display (200 Hz offset). Notice that it looks pretty good. Maybe just a tiny bit low. What's important is how stable that carrier is in the WSPR display over time with the GPS "good" sat count being a relatively large value (say larger than 4).

    Also, the backslash '\' key toggles which label database is being displayed. The name of which is shown in small white lettering in the top left corner of the frequency scale. Type 'h' to see a list of all shortcus keys.

  • QiwiQ a KiwiSDR client for Android: looking for feedback, testers and comments

    @XPloRR Do you write iOS apps as well? We've had many requests for a comprehensive Kiwi iOS app over the years. But no success in getting anyone to do it who would be remunerated by selling licenses on the app store (i.e. we have no money to fund development ourselves).

    Related: I mentioned previously that I bought a license. But currently there is no feedback when you enter the license key. So unclear if it's been accepted or not. Perhaps the linkage with the licensing backend isn't setup yet.
