My K3 (#3873) has better transmit and receive audio than my Mark V, which I thought was awesome. (Except the Mark V had a MUCH better internal speaker).
One disadvantage I have found with My K3 transmit audio is that you must choose between 2.7kHz or lower bandwidth or 3.3kHz bandwidth or higher. I prefer to run about 2.9 - 3.0 for rag chewing.
When using non-ESSB mode, you are limited by the crystal filter, and when the ESSB mode is engaged, you can turn the menu bandwidth down to 3.0kHz but it is really about 3.3kHz wide on the transmitted signal. This has been my experience on my K3 and watching other K3s on the air in the band scope.
It seems like a fairly easy fix to adjust the ESSB menu alignment so we can really turn our bandwidth down to 3.0 or even a little less. This is my request to Elecraft.
Thanks!
Dean
