Vibration is not an issue, the station is mounted on an inch and a quarter galvanized pipe with no movement at all. When i looked at the bottom plate it was full of water bubbles from the rain and when the bubbles were removed the readings went back to normal. Now without this problem the rain readings have been very good compared to the two eight inch gauges. I haven't had any high temp readings with my station but we seldom get calm winds down here so will watch for that problem when the conditions are right. Now the drizzle/misty rain is going to be an issue with something that counts rain drops when there are no drops to be counted. I had a rain that had big drops very far apart for a very short period of time and it showed .0022 inches and said very light rain so it just needs drops to count. I don't know what they can do to fix the main problem because of the water issue, it is what it is, two for two heavy rain and wind with the same results and the same fix to clear the problem. Down here on the middle coast of Texas we get a lot of storms with several inches of rain in a short time and gusty winds and this is a real problem in using it for a main station. I will just have tg go with the Davis anny and tipping bucket rain gauge. I don't know enough about the sonic set up but the water is the key i think because removing the water fixes the problem right away. I am waiting for the summer when the Texas sun hits the station and see how it compares to the other two and maybe the R.M. Young shield which i will probably put back in use when we get out of the dense fog period we get this time of year.
