[Elecraft] K3 and KX3 questions for Wayne

[brian]

Ray,

1 dB is generally agreed upon to be the minimum detectible difference in 
audio that people can detect.

Of course, these measurements don't include QRM, QSB or AGC action.

Big gun stations will kill to pick up 1 or 2 dB extra gain somewhere.

73 de Brian/K3KO

In most cases, a 6 dB difference in level is clearly noticeable, and that would be 25 watts vs 100 watts.   A 3 dB difference can be heard by most people, but a 1 or 2 dB difference is almost impossible to notice by ear.
