Radio Programming

I am soon to receive two Kenwoods (TK-790/TK-890), and the software to program them.



My question is this - there are other radios in the department I need to copy, so can I connect the computer to the head while they are set up together (two radios/one head) and download the load, or do they have to be separated before I can download the frequencies from each one?



Thanks!



Steve
