Steve,  I use a MFJ-1026 in sort of reverse mode.  The noise antenna 
connection is used to connect to my Beverage bank and the unit senses 
the exciter RF just fine and switches automatically.  My Icom IC-746 PRO 
also does not have provisions for a separate RX antenna.  You also get 
the ability to use the TX antenna as the noise antenna if you wish.  The 
unit has a switchable pre-amp and solvers the problem you described 
without surgery to the radio.  The MFJ also gives you some front end 
protection to RF pickup on RX antennas that could damage the rig.  Some 
recommend TX keying of the unit which is easy with a 12v line from the 
exciter as you may require.
