[BC] Part 15, er ... parts

[Bill Croghan]

	I guess the statue of limitations has run out.  We installed a 100
Watt "Collegiate radio special" AM transmitter with about a mile of RG8
daisy chained to 5 dormitories on the campus of the State University of NY
at Fredonia back about 1964.  WCVF was the call of the 600 Kilohertz
station, but of course back then we called it Kilocycles!  It fed Random
dipoles in the basements.  Tuning networks?  We were to dumb to use them. I
imagine the losses in the RG8 were enough that the transmitter loaded
reasonably well. It replaced some old Carrier current transmitters.  It
could be heard in all the dorms and about 3/4 mile off campus.  About the
time I left, they applied for a Class D FM and now run two FM's.
	We learn from our mistakes if they don't kill us!
