Wow that's a clean VLF/LF/MW spectrum from that 60m dipole. You must have ditched/upgraded all the SMPSs at your place. It's funny to see Jim Creek sitting +20 dB over a flat spectrum. Did you see that you have a beeper with a little bit of frequency wander on 176.65 kHz? I've always wondered if these were leftover LoJack systems before they moved to VHF. Maybe just NFC/ISM stuff? Will never know I suppose.

Thanks Brendan and everyone who contributed. Documenting these investigations is so important because now when someone reports a vaguely similar problem far in the future a little alarm bell will go off in the back of our heads and we'll ask "Oh, does your ISP happen to be Comcast? ".

Happy to hear that.

Even though you plug power into the Kiwi board it is first routed to the Beagle and its power management chip (PMIC) for monitoring, protection and switching. From there it goes on to power the Beagle and then back over to the Kiwi board. The PMIC has an absolute maximum input voltage spec of +20 VDC. It won't power-on at that voltage (5.8V is the limit) but it's supposed to withstand it. So that's why you got away with applying 9V.

However we have had a couple Kiwi/Beagles expire when reverse input voltage was applied.

Tremendous thanks to Pierre for providing this service to the Kiwi community over the years and for his efforts with this latest update.

Note that map tiles for Leaflet are now served by the same provider used by the TDoA extension and admin page GPS tab maps. This means KiwiSDR is paying for those tile serves out of the profits from selling KiwiSDRs (same as we do for the charges incurred in running the proxy service).
