[Elecraft] K3: An interested link

[David Gilbert]

Of course ... that's what happens when you have literally thousands of 
enthusiastic participants scrambling for limited space on the band, most 
of whom are trying their best to fit into the smallest possible slice of 
it.    So what part of that represents justification for taking up more 
bandwidth than is necessary to communicate?

This isn't a contesting versus ESSB argument, though, or at least it 
wasn't until you flipped it in that direction.  It's a question of 
efficient use of a scarce resource (bandwidth) on the HF bands.  It's 
like camping ... when you're out in the middle of the woods ten miles 
from the nearest telephone pole, go ahead and crank up your boombox and 
rattle the leaves off the trees.  When you're in a public campground 200 
yards from the nearest Circle K, have the courtesy to use your earphones.

Even with the K3, Elecraft tacitly acknowledges the risk of interference 
in ESSB mode when they state in the manual:

"Carrier and spurious signal suppression, passband shape, delay 
characteristics, fidelity, and other aspects of ESSB performance are not 
specified.  Use ESSB only after carefully monitoring your signal."
