Take a look at the Top Ten "Band Aide" band decoder, on sale now for $195 (regularly $295).

Should work fine with the Elecraft cable ($30).  Will control your RCS-12 DC relays no problem.  I've been using N3RD band decoders for decades; no failures.

Hi Group
I have been looking at a KRC2 as a replacement for my mfj RCS-12 that has reliability issues. 
Just wondering if anyone is using the KRC2 with their K3 to drive their remote antenna switch? 
If so, what are your likes and dislikes about the KRC2?
Please send your reply to me, as this topic  probably has limited interest..................de Rick,W6SR
