Bob:
When you go for SI then please stay with the convention, i.e. kilowatt is
abbreviated as kW and not KW. We are hopefully beyond the time when MAmp was
supposed to mean milliampere.

The ambient relative humidity should have no impact on the performance of the

In the olden times there were also voltage stabilizers based on vacuum

47 CFR Part 15, para. 107 and 109 identify CISPR 22, 1985 as an
alternative to the FCC limits. Inherent is the understanding that once
you make the decision to go CISPR then it applies to both radiated
