[Elecraft] K3 - 2.73/1.98 Clicks on Power On

[Ken K3IU]

I just reloaded firmware suite 2.67/1.96 and the problem exists there as 
well. I guess I have just never turned ON the K3 with a good signal on 
the VFO freq. One other thing I checked... with the AF Gain at minimum, 
the artifact is not there, but with even the smallest amount of AF Gain, 
the loud burst occurs and the "loudness" of the burst is a function of 
the AF Gain setting.
