You could do as some other people do and calibrate your console to Altimeter instead of Sea Level Pressure. Then you end up reporting Altimeter to all online services.*
* It is my personal opinion that option #2 I listed is not as elegant of a solution and think that is a hack solution.
Before I got my Vue console, I used this "hack solution" with my VP2 console, and it worked quite well other than very high and low pressure, and I'm at over 2400'. You tout that
only CWOP uses the altimeter (oh, btw, don't forget every media outlet in the country) and everyone else doesn't. Who's everyone else? Certainly no one I personally care about, others, no doubt. I even got WU to use my altimeter instead of MSLP, and if that throws off QC here and there, oh well, that's a drop in the bucket compared to all the other crappy data sent in the first place. Besides, I think people relying on others PWS data to compare to ones own is
mostly fool's errand as is, simply for the reason I just stated.
If the OP chooses this "hack", he'll certainly not be alone.
