I'd like to illustrate where the KXV3 could be useful even with a sub RX 
installed.  I have the sub RX but I don't have the KXV3. I frequently use 
diversity reception on 80 meters because my receive antenna is less noisy 
than my transmit antenna. But I usually end up with the balance control 
fully on the sub RX. Still not a compelling reason for the KXV3. The benefit 
occurs, however, when chasing a DX station using split. VFO A is on the DX 
frequency and diversity is turned on. But I can't listen continuously on my 
split transmit (VFO B) frequency.

In this situation I have resorted to listening to the DX station using the 
sub RX in an unlinked state and using VFO A to both listen and transmit on 
another frequency. In other words, split is turned off. This works well but 
it is not intuitive since I am operating split but split is turned off.

If I had the KXV3 I would probably tee the connector to both the AUX RF on 
the sub RX and RX ANT input on the KXV3.

Kjeld,
You have a very complete configuration here. If you want to save some money
you might drop the wide filters for the Sub Rx as they probably won't help
you attain your stated DXCC goals. They might help bag some broadcast band
DX if that is important to you.

You may or may not need the KXV3 for Rx antenna as the sub receiver allows
you to install a receive antenna BNC connector without the KXV3. The KPA3-F
also adds a second RF connector for transmit/receive. Study the antenna
switching part of the manual and determine if you need the KXV3 for your
stated purpose of adding an Rx antenna. I don't have the KXV3 and I do have
a separate Rx antenna port. If a band scope is important down the road you
will need the KXV3. Depending on your operating style the band scope would
help you attain your goals, your mileage may vary.
