[Elecraft] KRC2 relay boxes used?

[Maarten]

I use the MFJ-4716, 6 port Remote antenna switch. I believe there is also a
4 port switch. This switch is very easy to connect to the KRC2 and works at
KW level. Each relais can be activated with 12 V volt from the KRC2. You can
make the connection via with RJ45 connector on the back of the MFJ box. It
requires a little reverse engineering to figure out which wire activates
each port.
