Smaller signals get no significant diary mentions.

How often do shortwave entries show up in the diaries?

I have been reviewing diaries since 1970 (you have to go to Arbitron in
suburban Maryland to see them) and have never seen an SW entry.

More specifically, I saw the forms for the ratings in Quito and Guayaquil,
Ecuador, in the late 60's when I operated stations there. Not once did I see
a SW station mentioned there, either.
