The six-pack needs +14 volt drive to enable its relays. Power is
applied to each antenna relay to be selected. This is usually provided
by the Six-pack switch or an external decoder/driver such as the
Elecraft KRC2. The K3 alone will not be able to provide the drive - it
definitely needs the external band decoder.
Of course we suggest the KRC2 for this function, it performs the
service quite well.
