[Elecraft] KX3 vs. K3 and other rigs?

[David Gilbert]

It all depends how close the desired signal is to the noise level.

However, the original argument that 20 watts is better than 10 watts 
seems pretty silly to me since you can carry that flag all the way up to 
power levels that create their own ionosphere.  We can all gain >FAR< 
more ERP from wisely choosing/building a better portable antenna 
compared to a backpack whip than we would from doubling the power out of 
the rig.
