From this console, the operator could
monitor and control nearly all portions of the transmitter, from the modulators
to the final amplifier tuning. Once again, due to the narrow bandwidth of
the antenna, the operator needed to keep a close eye on the tuning. The
resonant frequency of the antenna could change due to winds moving the wires
or static fields from approaching thunderstorms. At one million watts
input, proper tuning was VERY important!
