5 stars Tho it took effort, it did what I wanted - 100% success!
Looking back at this, it's not that difficult to set up. But having tech support at Davis help made short work of getting my station on the APRS map. The real complexity was how to register the site with NOAA - nothing to do with Davis or WeatherShack (who CORRECTLY identified the Davis Instrument system as the ONLY one really ready-made to run on the CWOP/APRS system)...

3 stars A real pain in the _ _ _ to set up
I still haven't got it working yet. I "may" consider spending money on one of the additional packages that are available, but I will not do this until I can see data from my weather station appear in WeatherLink.

5 stars Software for Davis weather logging
Software is easy to use and immediately recognized my Davis sensor and console.

1 stars needs wireless
Unable to use it because it is wired, and it's in a different room then my computer. I have not been able to find a device to hook to it to make it wireless.

5 stars A must-have.
Great capability. I don't like the way the pigtail sticks out the bottom of the console but it's not a show-stopper.
