  • wifi connection and local time

    The "-s" in "curl -s" (silent mode) is preventing us from seeing any error message if the connection is failing.
    What happens if you do:
    ping kiwisdr.com

    I'll bet this is a problem with DNS not working with WiFi for some reason (router configuration problem?)
  • KiwiSDR production status and availability

    The build count has stabilized at 204. So Seeed seems to have built the promised 200 units plus a few spares.
  • KiwiSDR production status and availability

    I'm only guessing here, and I don't mean to show favoritism towards particular distributors, but my bet would be ML&S (UK) and WiMo (DE). I wouldn't order from Mouser (USA) until they show units in stock (they had an issue earlier in the year with not filling a large backorder in the correct queue order).

    As of this morning the total count of Kiwis that have been through factory final test since Aug 19 is 186. So depending on the delay shipping to the distributors we shouldn't have to wait much longer now.
  • AGC control

    Currently, when you connect with a browser, the default AGC threshold is -130 dB. In the past this default was -100 dB and there was disagreement about this choice and discussion about whether it needed to be automatically adjusted depending on passband etc. Remember that certain values in the UI (including the AGC values) are saved across connections via browser cookies. So what you see in the AGC tab of the control panel may not be the true default.

    Kiwiclient (kiwirecorder et al) allows you to turn AGC on and use a fixed set of parameter values (set in the Python code) or turn AGC off and set a manual gain, all via the --agc-gain (or -g) [gain] argument. The fixed values as defined in the file kiwiclient/kiwi/client.py are:
        def set_agc(self, on=False, hang=False, thresh=-100, slope=6, decay=1000, gain=50):
            self._send_message('SET agc=%d hang=%d thresh=%d slope=%d decay=%d manGain=%d' % (on, hang, thresh, slope, decay, gain))
    So Kiwiclient is using -100 dB as the threshold which is at odds with the current browser default. Although not with what some people may have it set to. There is for example no Kiwiclient --agc-threshold argument, but it would be trivial to add. If you peruse the code you will see other references to "thresholds" but those are for NBFM squelch and RSSI thresholds.
