All the Drake 4 Lines have that. You can use the T4Xnn with the receiver as 
seperates or use either VFO for transceive. Its a fairly flexible setup.

If you were to build your own transmitter that is designed to work with the 
R4 you would be able to use that injection. I dont believe any other 
manufacturer used the same frequency scheme.
