Does anyone know the spec for the machine screw that holds the circuit board down on the corner with the antenna, on the original Vantage Pro 1 Wireless sensor suite?
This station has been in service for 19 years. The power storage capacitor needed replacing (second time) so I had to remove the circuit board. Working on the mounted ISS with the board upside down, I had a large pan underneath to catch the inevitable drops. Unfortunately it didn't catch this screw, and it's the only one like it in the unit. The others are self-tapping, but this is the one that is in contact with the antenna, so it's a machine screw.
Even Davis doesn't remember what it was. They can't even say whether it was metric or standard.
Any help would be appreciated.
