[Elecraft] K3 and KRC2 for controlling 12VDC

[Don Wilhelm]

Rich,

If the RX antenna is the only thing you want to control with the KRC2, 
the answer is easy - just use the KRC2 configurator application to 
select the outputs for the bands you desire.
The High level outputs can provide the source of 12 volts (up to the 
current limit of the drivers).

I am not sure what that has to do with the DVK messages - I do not see 
how those can be related.
