@la6lu that made me smile...
I too had problems with the factory fan and replaced several with Clint's suggestion https://www.alltronics.com//cgi-bin/item/28F082/search/Sunon-5V-Fan-Size--30mm-x-30mm-x-6mm-

I've now replaced four fans with this alternative but have just recently had to replace one of the alternatives when it too started to get noisy at the remote, poorly climate-conditioned site. It gets both hot and cold at that remote site so maybe this is to be expected. If someone finds an even better substitute or can identify a good maintenance plan for these (change oil every 20k km?) I'd be interested. Maybe this is just going to be part of the cost of keeping a Kiwi running continuously...

Actually, I think the power has been on the whole time. The issue seems to be a poor quality router that loses its way and no one having access to help it out. There may be plans for a replacement but there is perhaps a little politics in that one. Perhaps Rob may be able to elaborate.

I'm finding that "it works sometimes". I managed to get it not work, QSYed to a ham band where it worked, fussed around after which it quit. Maybe someone else can figure out the conditions for (non)working.

I haven't documented the kiwiSDR onboard GPS performance but I have examined it, particularly in comparison to use of the Kiwi with an external clock. You can do the same by comparing two of my kiwis, one with a Bodnar GPSDO which generally appears to be better than 1 ppb and to not limit the phase noise performance of the kiwi with another using the on-board GPS reference.
Bodnar referenced Kiwi
and
on-board kiwi GPS
are both looking at US NIST LOS/"groundwave" signals transmitted from less than 20 km distant.
This may not be entirely satisfactory since the on-board kiwi's GPS antenna is outdoors but not very well located.

I think many of us find the low end not dark enough and routinely adjust it to dark blue. jks has mentioned this too, I think.
