[Elecraft] Microphone Jack Grounded?

The K2 ~01583 that I have did not have its mic jack shield
grounded. The above document implies that Elecraft omitted a
step to ground the jack, so I assume that the omission will
have been corrected by now........"

I noticed the instructions were dated 1999.  Has the mic
jack been grounded in later kits?  If so, starting with what
numbers?  My K2 is #2636 and I just don't remember much
about this.  Looking at the schematic, it's not obvious ( to
me, at least) that the body of the jack is grounded.
