The Kiwi is in a house where there is no computer, only a tablet.
The 3 power supplies are linear regulated ones : Kiwi, antenna, WiFi interface (Linksys)
I have birdies from 10 to 30MHz : http://f1jeksdr1.ddns.net:8073/?f=27950.40usbz6
This seems to be computer noise. But which computer ? The Kiwi (which is under the roof) ?
Help ? Any idea ?
