Thank you, that is usefull information for everyone!
I haven't decided what to do. I might fix my nanoVNA, buy another or wait for the announced "nanoVNA 2.0". My version isn't completely dead but the pc-usb interface stopped working, which I think is caused by a bad usb connector. My nanoVNA lacks RF shielding (unlike yours) and comes with a simple enclosure (like yours). I would like to have a better enclosure, because I like the NanoVNA and would love to keep it working.
If RF-shields and/or enclosure is available for not to much I would like to hear about that too.
