Thanks DanS
Wow that is quite a thread
I am running wireless from the Transmitter to the console
The console readings are ok
The Desktop PC (Windows XP) is running Heavy Weather software (as requested by VWS)
The HW software readings are also ok
The PC is also running VWS software and that is showing the faulty readings
VWS uploads to WeatherUnderground which also has the false readings
My logic is could be that the problems is in either VWS or WeatherUnderground
I'll keep you informed
