Don, and all:
I don't think diversity will work with different VFO's. Both Rx need
to be in phase from one LO for diversity reception to work.
I run diversity Rx on 2m with RF channels that are orthogonally
different polarity and that feeds dual IQ baseband thru a four port
soundcard to my
Removing the entire left side panel makes installation of the KXV3B
module even easier.
As an additional hint, bend the pins of the KXV3B connector slightly
toward the front - about 1/16 inch at the tips of the pins is enough.
That will allow you to more easily install the new option.

What I do is switch antenna connections. My secondary antenna is

the main + secondary antennas in diversity mode, just the main antenna

Even if your current antennas are resonant on all
bands, there are portable ops and other situations
where you might want to try another antenna.
The internal tuner of the K3/K3S is very capable
and well
AND - with the tuner you get a second SO239 antenna port - from front

May sound trivial - but eliminates one more accessory hanging on the K3 .

If you add the KPA100 to the base K2, then those options that are
