Hello:  It used to be here in Canada that there were 2 professional radio
licenses, the first and second class.  This has been dropped in the last few
years for another license which I cannot recall the name of the GRMC I
"think".   Can anyone tell me if there were commercially available study
guides for these older licenses and who printed them, and please, what the
names of the books were?   Thanks a load.
