I suspect that for Farnsworth - just use the character speed - not the
overall speed with extended spacing.

That and wondering what a CW signal Bandwidth was in the first
place.
------------------------

From the ARRL License Manual 1976:

CW Bandwidth = wpm X 4
"With proper shaping, the necessary keying bandwidth is equal to 4
times the speed in words per minute for International Morse Code;
e.g. at 25 words per minute, the bandwidth is approximately 100 cycles.
e.g., 40 WPM = approximately 160 Hz"

Does the ARRL License Manual of 1976 address Farnsworth code and
bandwidth?
