I was an AM radio Disc Jockey when I was in High School. Some of the other older guys will remember how it used to be. It wasn't unusual in those days to work at a small time radio station when in High School. I also worked part time for AFRTS when I was over seas in the Army. And went back to radio after the Army. It's really a much longer story. I tell this story sometimes in some of the Inmates Threads like in the MNwilly Memorial Stay Sober Thread.
It's been over 41 years now since I was last On the Air. Some parts of such things are getting foggy and sometimes the memories are like it happened yesterday.
Sorry for all the digression. Now back to clutch repair.
Never memorize something you can look up.
