G'day,

<snip>
Today in Hong Kong we have relative humidity (RH) of 55% (temp a 
'freezing' 16 C), compared to our norm of 90 - 100% RH and temp 30 C+
<snip>

I assume the 16C was outside not inside.

<snip
These past two days my daughter and xyl have mentioned several 'static 
shocks' when they play with our cats, all 6 of them.

I remember my school kid days of cats tail static generators, but there's 
a serious question behind this. Under what conditions of RH do most 
builders of Elecraft rigs operate?
<snip>

RH in the house is of the order 40-60% temp 20-22C most of the time.  No 
cats, no ESD countermeasures besides touching an earthed object before 
picking up sensitive devices.  Not killed one yet.

Regards,

Mike VP8NO
