v1.443: automatic SNR measurement, queue/camp panel reload button, misc fixes
From the CHANGE_LOG file:
v1.443 March 22, 2021
Added automatic SNR measurement:
Every 6 hours (4 times daily) a Kiwi will connect to a free channel (if available)
and measure its own SNR. These results are available in JSON format from the
URL: my_kiwi:8073/snr (adjust Kiwi name and port number as required).
This URL is publicly accesible. Disable on the admin page, control tab if you
don't want to share this information.
The measurement details can be easily changed. Suggestions welcome.
SNR is currently defined in the same way as used by the sites snr.kiwisdr.com
and snr2.kiwisdr.com, i.e. waterfall dBm values, sorted, noise = 50th percentile
value (median), signal = 95th percentile value, SNR = signal - noise.
Two measurement bands are recorded: 0-30 MHz and 1.8-30 MHz in an attempt to
filter out the AM BCB. The JSON data also contains min/max dBm values and a
timestamp (local time unless the "UTC" value is set).
Added "reload page" button to queueing panel ("camp" parameter is removed from URL)
Use to quickly access any Kiwi redirection that might be available.
Autoscale button and aperture auto mode now disregard masked areas from calculations.
Admin page UI changes:
GPS RSSI now red color for sats not actually acquired (i.e. no subframe decoding)
Registration now requires a valid location field (for benefit of map.kiwisdr.com)
