You're absolutely right, in a perfect world. However, the times when
CW is most effective are usually times when digital decoding
equipment either is unavailable, or can't be used because of power
constraints. How much digital communication came out of the areas
hit hardest by Katrina? There are times when the simplest method is
the most effective, and CW is the simplest way to communicate. In
worst case, you don't even need a key - you can just short two wires
together to turn the transmitter on and off. I've even heard of
cases where an operator sent CW by keying the mic on an HT. Ever try
simulating PSK31 by whistling into a microphone?
