No, it is limited to the bandwidth of the preselector filters at best.
Since the two meter transverter uses 28 MHz as an IF, that would be
roughly 28 - 30 MHz.

Front end (at 2 meters) RF splitting is not practical since the
transverter does not have an externally accessible RX Ant loop
(like RX Out/RX In on the KXV3/A/B).
