OK, here is a cheap solution which works fine for me and I don’t have any crashes anymore.
You see the USB connection close to the station. This is the weak point. Davis shouldn’t split the cable but should have one cable going straight from the WS to the PC. I guess their designers were asleep at Uni while the subject was “Interferences”.
All you have to do is wrap the connection with Aluminium foil.
Also pull the power cable apart from the USB cable and don’t let them run too close side by side from the WS to the PC. Don’t wrap the power cable around the little pins inside the station as Davis recommends it.
Cheers
PS: Davis, if you need a hand with your stations and need some more tips and design solutions, you can contact me (and in return send my money back for the station I bought).
PPS: An additional component (eg. a Daytime Fan Aspirated Radiation Shield Kit or an UV-sensor) would do too.
