I have run the 3020 for a while but kept going back to WD for the extra functionality, link with wxsim for forecasting and sending automated weather reports etc, but its always been a bit of a love/hate relationship until recently when I find if I try to upgrade WD to the latest version my temp defaults to =2.2c and stays there, which as we are in summer seems a bit extreme, it is also corrupting the log file with a similar, Brian couldn't find anything so must be something in my setup, so basically was looking around for a simpler solution
