Yes. But I don't know of any cases where normal repeater splits go  
across 146 MHz. And in any case you're limited to 144-146 MHz in HB- 
land, last time I checked :)

Regarding another question posted here: The K144XV module has two  
advantages over our external 2-m transverter (the XV144). It's  
internal to the K3, and covers the full 144-148 MHz range. The XV144,  
being external, can be used with other rigs besides the K3, and has  
higher output power.
