Worried about time?
The latency of the KiwiSDR scheme may thwart synchronicity a bit but you may have other needs for precise time. I do various radio related things that require accurate time and was left hanging one day when the Internet went away and all my RPi, BB etc. were left to drift. To fix that I took an older/slower RaspberryPi I had and added the Adafruit 66 GPS module. I was able to get that to provide clock to the ntpd on the RPi and by using pps, I have a local clock accurate to within 10 uSec. I now point all my computers to that RPi for their time. If the GPS scheme fails, normal network time, which is usually available, takes over.
