[Elecraft] [K3] [KRC2] Is there a KRC3 in the works?

[Don Wilhelm]

I agree, with the wire-OR capability of the KRC2 outputs, I do not 
understand why a configurator program is needed at all -- unless you 
have need for multiple configurations -- for example, one for contests 
and another for normal operating.

If further expansion is needed, adding some additional diode steering to 
the KRC2 outputs, many sophisticated switching arrangements can be 
realized, all with the default configuration.  The AC1, 2 and 3 outputs 
can even be used to switch from one bank of antennas to another 
controlled by the switches on top of the KRC2.  Sophisticated logic 
switching like that can be accomplished by driving both the + and - 
sides of the relays from the  high and low side outputs of the KRC2 in 
various combinations.
