[Elecraft] K3 - Band Decoder

[J. Heide]

OK, now that the Katiegram has arrived, I need to think about antenna switching. I have the following antennas that I want to use with the K3
Windom for most all bands
Yagi for 20 meters
Yagi for 6 meters (goes to the XV50)
Vertical for 160 meters
Vertical for 6m FM (which is not used with the K2)

Right now, I have a KRC2 that switches the 20m yagi and 160 vertical on antenna port 2 on the radio. Since the K3 has 4 band decoder (TTL?) lines coming out of it, it is easy enough to build logic to pull in the right relay. Can the "DIGOUT" line be used (with proper buffering, of course) to switch a relay for changing from horizontal to vertical on 6m? Basically, windom and 6 meter antennas to antenna port 1 (with the band decoder switching from windom to 6 meters, and digout selecting wither the vert or horiz) and the 20m beam and 160 vert switched on antenna port 2?

I have several RelComm RDL-SR002 relays, one of which I am using with the KRC2 now, so quality relays are not a problem here.

Sorry if this is a bit long, but without equipment in front of me, I have a hard time visualizing things.
