@gk -- thx! quite an accolade... muchly appreciated...
So, I decided to go ahead and do this course. If nothing else it "sounds" (see what I did there?) like a lot of fun. I mainly want to see what a "pro" setup looks like, learn about mic technique and maybe -- just maybe! -- see if this might be the beginnings of a late-in-life second career. It starts Wednesday May 11 (about a month) and I'm already looking forward to it!
On a side note... The course description says, "This course is held at Joy FM Melbourne." It does not say, "This course is held at Joy FM Melbourne, an independent voice for the diverse lesbian and gay communities in Melbourne." Their broadcast building is in a very conveniently central place in Melbourne, possibly one of the reasons the course is held there. I have no problem at all with the nature of the station; I just think some folks who want to do the course might be in for a little bit of a shock :-)
