[Elecraft] [K3] : Mic connection

[Raymond METZGER]

Hello Elecrafters,

I am playing with my K3 and just realized that the "Up" and "Down" buttons
of my Kenwood MC-43S microphone do not work on  the K3 as they work on the
K2.
On the K2, whatever button is pressed, the frequency shifts from the one on
VFO A to the one on VFO B. On the K3, nothing happens.

This doesn't seem to be in line with the Owner's manual (see page 13 of
release C1 of the owner's manual).

Something wrong with my K3 ?
