A little typo on my last one:

Part number for the cable to go from  the RB 704 to the Kenwood is PNP 7D. 
These cables are radio specific.  The RB 704 buffer comes with 2  cables to 
go from the unit to the amp.

No matter what  sort of keying buffer, interface, or line you wind up with, 
it will need the 7 pin din plug to mate with the 430.
