The Banana Boat Swing and Other Distinctive ‘Fists’ (1996)

Vying for importance with the operator’s fist, was the matter of his rigs CW “note”, the T in the RST system. There were many one stage, “self excited” rigs used on CW in those days, in spite of the dire FCC and Handbook warnings against coupling simple rigs of this type directly to the antenna. And then there was the special breed of CW operator, usually a high power fanatic in southern California who sported a crystal controlled KW+ rig, the signal from which was modulated at 120 (or 100) cycles (there were very few Hertz around in those days).
