I think "pop" is a very inaccurate description of the sound, at least in my "stock" K3. Here's it's more of a quiet 'bump-bump' sound when the power is cycled, even in a very quiet room.
It's very low frequency, so perhaps those K3's whose audio has been enhanced to emphasize the very low frequencies hear it louder, but it's quite unremarkable on my K3.

The K3 audio amplifier has a characteristic that results in a "pop" when power is cycled. This is normal; it has been present from the first units. 73, Lyle KK7P ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
