• After witnessing the continued decrease of involvement in the SpotterNetwork staff in serving SN members with troubleshooting issues recently, I have unilaterally decided to terminate the relationship between SpotterNetwork's support and Stormtrack. I have witnessed multiple users unable to receive support weeks after initiating help threads on the forum. I find this lack of response from SpotterNetwork officials disappointing and a failure to hold up their end of the agreement that was made years ago, before I took over management of this site. In my opinion, having Stormtrack users sit and wait for so long to receive help on SpotterNetwork issues on the Stormtrack forums reflects poorly not only on SpotterNetwork, but on Stormtrack and (by association) me as well. Since the issue has not been satisfactorily addressed, I no longer wish for the Stormtrack forum to be associated with SpotterNetwork.

    I apologize to those who continue to have issues with the service and continue to see their issues left unaddressed. Please understand that the connection between ST and SN was put in place long before I had any say over it. But now that I am the "captain of this ship," it is within my right (nay, duty) to make adjustments as I see necessary. Ending this relationship is such an adjustment.

    For those who continue to need help, I recommend navigating a web browswer to SpotterNetwork's About page, and seeking the individuals listed on that page for all further inquiries about SpotterNetwork.

    From this moment forward, the SpotterNetwork sub-forum has been hidden/deleted and there will be no assurance that any SpotterNetwork issues brought up in any of Stormtrack's other sub-forums will be addressed. Do not rely on Stormtrack for help with SpotterNetwork issues.

    Sincerely, Jeff D.

Our new Davis Vantage Pro2 with 24 hour fan-aspirated radiation shield has been in service for 1 week today. Therefore, I have another question for all the Davis experts.

Since I have other temperature and humidity gauges, I have taken the time to cross check the temperature and humidity readings on the Vantage Pro2 unit .......... several times. Everything seems to be running relatively close. However, I do not know which of my gauges are the most accurate. In your opinion, are the Vantage Pro2 units extremely accurate or should I expect that I will need to enter some offets? Outside temperature readings on the Vantage Pro2 are running about 2 degrees lower than my DTH-1A (A.W.Sperry unit) and lab thermomoter. Outside humidity is running about 8% higher on the Vantage Pro2 as compared to my DTH-1A (A.W.Sperry unit). Inside temperature and humidity readings are almost identical on the console unit and the lab thermometer and DTH-1A (A.W.Sperry unit)!

Since the Vantage Pro2 is new and probably was calibrated before leaving the factory, I'm thinking it is the more correct and I probably shouldn't be entering offsets! Any thoughts?

So, thanks again!

Get the old fashioned sling psychometer and check your humidity readings! :p J/K

Temperature will vary between devices. It's a given. If you have 3 devices that are all off from each other by a degree or two, you can (A) Not worry about the differences, or (B) take the average between the three and go with that.

I always used my local airport readings to guage against what I had, but then I had a mobile set up too. With your stationary set up and the fast it's in an asperated shield, that will make some difference right there. Air movement and cover as opposed to less movement and no shade.

I used a sling psychrometer on mine and it needed no offsets (other than elevation for barometer). Temp/dewpoint are always within one degree of the Lee's Summit ASOS which is 2 miles away and the SLP is always dead on.

Agree with John, get a nice sling. You can probably pick one up on Ebay cheap -- not sure if their rules allow the transport of mercury ones though...
