Hi Gord,

Thanks for the info and I think your English is fantastic (1000 times better than my Portuguese)  

I believe I'll go with the Pro2 Compact, seeing as how it comes fully assembled and tested and can be powered by the USB. I'll probably have enough to worry about. In the specs, it says something about it not having a "Davis Data Logger". Does that mean it doesn't store the data it receives from the TX/sensors? so if I don't have the data send to somewhere it will be lost? I.E. if it's not connected to a PC or WiFi.

The Data Logger stores data for a period of time (more info here) which depends on the data log interval defined on the software (usually 5, 10 or 15 min). In practice, most users use the PC or as PI for a long term data storage, so the logger is only useful in the eventuality that you have to turn off the computer for some days, otherwise it may no be so important as it seems (all Davis weather stations come by default without the Data Logger).
So, its a user choice, considering how each one intend to use the system.
The uploads to Wunderground aren't affect by the existence of the Data Logger, as they occur since the receiver is powered and configured to upload to WU.

So, to get started, how do I order the Transmitter and Receiver?

Just send me a PM with what you want to order, then I will reply with all the details.

Regards
