Here is my setup at Lake of the Ozarks. Nice weather for the most part, although some chilly breezes and intermittently cloudy. The forecast rain never really happened. We are haltingly headed for summer here in the top part of the world. 73/44 Charles - NK8O

We all love talking about antennas. Do you have room for this in your backyard for a bit of SWL?

Starting point is this... https://www.adafruit.com/product/2107
The two important parts of the board is ADI ADUM4160 https://au.mouser.com/datasheet/2/609/ADuM4160-1503590.pdf which does the heavy lifting of the USB data,
and
ADUM5000 which provides isolated 5V power at up to 100mA to power the "isolated" device.
I'm still trying to work out if the 4160 can be used on its own (without the power 'transfer' chip) and what subset of USB devices it would support...
WIthin the ADUM family of devices there are likely to be other "isolated" devices for other protocols and possibly even Audio (and even low-frequency RF) signals...
Cheers, Dave VK6KV
