Here's my latest project, a solar powered station using ham radio to link to my base station. It uses an Ambient WS-2902 array, Ecowitt GW1000, and a raspberry pi zero running WeeWx. It's currently in my back yard, hopefully next year it'll be on a hill overlooking a cornfield.

Out of curiosity, how does the VV-898 perform as an APRS transceiver?????

Very nice job! Specs on the solar panel?

It works quite well in a rural location. Low current draw and good sensitivity. I would not recommend it in suburban or city settings, however.

It's a 30W Newpowa panel. I thought it would be adequate for a station that draws 3.5 watts, but I appear to be mistaken. I am going to upgrade it to a 75 watt panel.

This is really cool.

Update:
I have made some modifications after testing. My previous method of burying the battery flooded so a larger battery is in a vault with good drainage. It now has a 75 watt panel and the solar controller has been moved into the cabinet.

I have also installed a voltage and current sensor and can read five parameters through telemetry. As a test I disconnected the solar panel and found that the battery alone will run it for 5 days and 20 hours.

Great setup, would you mind to explain all you can did it (a little guide how to)

Underground battery?
Keeps it warm?

I dont think warm, maybe an stable temp.

Thank you. It has turned out to be a much larger project than I envisioned. I am in the process of documenting all of it. I hope to have it published in QST, the journal for Amateur Radio in the US. If so I will supply a link or copy here.
As a note on the progress: My battery will power the station for almost six days, so of course Mother Nature tested me with eight cloudy days. I'm now working on a small UPS and shutdown device for the pi.

As mentioned before, just a bit more stable.A little less cold in the winter and not so hot in the summer. The vault lid has a provision for a security screw so it also makes it a bit more vandal proof.

Excellent setup!

Hello! Have you published somewhere what and how your weather station was assembled from? Please provide a link.
