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.
