[Elecraft] [K3] Pull-up question

[Jack Brindle]

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.
