have provisions for routing RX ANT only to the sub. But there are three
other sources you could use for the KRX3's aux input: (1) the SO239 at
ANT2 (normally supplied only with the KAT3, but you could order one and
install it just for the sub);"

If I am reading this correctly, I do NOT then have to order the KAT3
if I only want an extra rx antenna input to route to the subreceiver.
And I can use the KXV3 rx ant input for the main rx with the ANT1
input for transmitting.  This setup is for diversity reception with
two rx antennas.

ANT1 - transmit antenna
KXV3 - rx antenna to main rx
ANT2 SO239 (no KAT3) - rx antenna to sub rx

Can someone please confirm this will be doable from the outset of K3 production?

Thanks & 73,
