The question kind of states it. I suppose that the BW might be wider as
the speed increases.

Mike,

The bandwidth of a Morse signal is determined by the rise and fall times of the
leading and trailing edges of each dit or dah, and the shape of the rise and
fall.


The reason I ask is that on 3580 tonight, we're all sitting there fat,
dumb, and happy, when W1AW starts it's CW broadcast.

Who is "we", Mike?

And it's some 700
kHz wide!!!

How did you determine the bandwidth?

And now I'd swear it's almost 3kHz wide. That's like SSB!!!

Yep. Such a bandwidth would require extremely "hard" keying, though. Or a
modulated carrier.

Needless to say, their strong signal was pretty tough on all us 5 and
ten watters. you could get most of a message through, but it took a lt
of the fun out of it.

Was the AGC on?
