I'm thinking of a relay at that point to switch between them. But then I guess there goes your isolation afforded by the BNC. Would a Y cable affect the input Z enough to affect the gain?

I used the Elecraft-supplied BNC(F) to TMP(M) cable to feed the sub-receiver's input. This arrangement is essentially "permanent" unless one does a partial dis-assembly to gain access the sub-receiver's input jack. I later decided that I'd like more flexibility regarding the choice of antenna for the sub-receiver. I now route the cable from the BNC(F) to the area atop the sub-receiver and secure it to the knurled nut on the top of the sub-receiver. I also routed the cable from the antenna tuner to the same area and secured it along with the end of the cable from the rear panel BNC(F). Next I made up a short (6") TMP(M) to TMP(F) cable that plugs -permanently- into the sub-receiver's input. This short cable is also routed to the same area as the ends of the other two cables. Now, by lifting the top cover of the rig, I can choose which source is fed to the sub-receiver's input via the short extension cable. It's -much- easier to gain access to the sub-receiver's antenna jack if the KI03 is removed. It's easy to damage the input jack on the sub-receiver if you try to plug a cable into the jack from above. 73!
