[Elecraft] K2 Improvement Ideas--Adding on

[Don Wilhelm]

Vic,

Yes, two relay boxes (actually I am using 4 in total - it may expand to 
5 sometime).

The KRC2 can switch multiple relay boxes - switch both boxes for any one 
band and then select between the relay boxes with the ANT1/2 selection.

In fact, with the KRC2 there are both positive active (external power 
supply) and negative acting (grounded when active), so these outputs can 
be combined logically by simply wiring them together - logical OR as 
well as logical AND functions can be created.  The KRC2 is truly a 
versatile relay controller.

73,
