Drew,
True diversity reception requires 2 receivers which are locked together
in not only frequency, but also in phase.
The KRX3 receiver is of the same design and implementation as the main
receiver, making diversity reception possible.
The antennas must be different, one horizontal and the other vertical as
one example although other combinations are possible - not only
differing polarization but oriented in different directions.
The result is that an "option board" for one receiver will not create
the conditions necessary for diversity receive - two receivers can
produce that result.

I don't know all the technical details of diversity reception but have
wondered if a diversity mode option board could be produced at a cheaper
price than a full-blown sub receiver. Not sure how much I'd be willing
to pay but sub-receiver pricing is definitely a no-go.
