[ICOM] IC-7000 AM Modulation Problem

I am not sure what is obvious.

I think that more Canadians run lower power than Americans (of the US type).

However, what power that one operator runs and what results that operator obtains 
is difficult to ascertain,

Most of the operators that I know of run barefoot.  There are very few who run top 
power.
