OK
I have read this kind of texts:
http://elecraft.365791.n2.nabble.com/CW-Rise-Time-td3218979.html
I do not have a K3.
In case K3 does not have a setting for CW edges, I am surprised.
This means there has been a number of changes to the initial factory
setting - for some reason.
Is there a possibiity in K3 to upgrade the firmware?
I presume it is much more difficult than a setting in a menu somewhere.
