[wxqc] Pros and Cons On OSI WMR-968

[Victor Engel]

Wow, you got a snapshot when my station (Allandale North/Wooten) and
my neighbor's (North Central Austin SKYWARN) (both on page 5) had
nearly identical readings. Although we both have Davis equipment, our
readings frequently differ, partly because his citing is restricted by
cabling (I've got the wireless unit, he does not). His RH is usually
higher than mine during rainy weather. I suspect mine might be higher
than surrounding stations during calm weather because I keep the grass
very tall and I have a pond. Anyone have any notion for how much these
situations would affect RH readings?
