[Antennas] Antenna lead in coax

Tue, 25 Nov 2003 12:35:33 -0500

Jim must be a really old fart - when was the last time anyone referred to
MHz as Megacycles?

I remember when I worked at WCSI in 1948 with another young broadcast
operator who drove a Harley Davidson 125. The announcers would sometimes
give the station break with "WCSI, operating on 93.7 Megacycles and 1
Motorcycle"
