[Elecraft] K3: switching on click

[Don Wilhelm]

Mike,

If you are using amplified speakers, that difference is to be expected.  
I use unamplified speakers, and all that is heard is a muffled couple of 
pops - it is not in the range of anything annoying to me.

You are hearing the large value capacitor in the AF output charge up 
(the capacitor is not as large in the headphone amp in the K3, and the 
amp is a different one).

The K2 does the same thing - and at my workbench I do use amplified 
speakers - yes, it can be annoying with amplified speakers.

73,
