What is a WWII "command radio" like the SCR-522 for?


I'm curious...I was looking through info on the P-61 Black Widow, and among the numerous black boxes it lists the "SCR-522 Command Radio". I've looked around a bit, and found a few references to it and other "command radios", but I still don't know what it's function is. The nearest I can guess is that it is sort of a "master" radio set that combines the info from all the other radio devices. Obviously one man couldn't operate as many different pieces of equipment as are listed in the P-61 individually. Am I right? Is "command radio" a term for a "master radio" that is the ultimate "user interface" for complex multi-unit radio systems?

The SCR was an acronym for Signal Corps Radio. The 522 was a VHF set that was used to communicate with the tower. The aircraft electronics weren't so sophisticated as to have a master unit that controlled all the others. They had fixed frequency sets that could be turned on or off and some sets with three or four channels that were tuned to specific operating channels as well as DF or Direction Finding units and IFF units.
