I find this article interesting as I run a very low power am / fm radio station under part 15 of the FCC rules. the signal is very localized to my apartment complex where i live and i use professional broadcast grade studio equipment as well. what is pictured in that article is what would have passed as professional broadcast grade equipment in the 1940's.
