It won’t directly drive either. The K3/K3S outputs BCD band data. You need a decoder box to convert that into direct drive signals (high side drive) for both of the antenna switches. The Elecraft KRC2 will do the job quite well, as will quite a few other boxes. Be sure they have TTL-level inputs. The ones with opto-isolators tend to require quite a bit of current, more than the K3/K3S may be able to drive. Some will work, others, even from the same manufacturer will not.
