No mods are needed.  The VX-3Rs for North America transmit and receive
across the 430-450 MHz range, so you are covered for satellites at 435-438
MHz.  You will not have full-duplex operation with that radio, but can use a
couple of ways to work the FM birds.  I programmed groups of memories for
each satellite in the VX-3R I previously had, and it worked OK.
