#22 it isn't that simple.
Consider this ... ..the only use of the call sign "Marine One" is for radio traffic between aircraft and airports. Air traffic worldwide is on non encrypted AIrband frequencies on the AM spectrum. Those can be monitored by the general public with a $20 radio. With some duct tape and $10 worth of wire, a teenager can build a pair of antennas that can triangulate the location of an airplane radio transmission with damn good accuracy. Think of what an assassin with better equipment can do.
Now, consider that at least part of the purpose of flying multiple identical helicopters is to prevent a would be assassin from determining WHICH helicopter the president is on. Do you think they would intentionally put a screaming electronic radio beacon on one of them that says, "The President is on THIS helicopter, and it is RIGHT HERE" every time the pilot keys the mic? Of course not. That would defeat the purpose of flying the whole squadron.
MAny decades ago, your premise was correct. During my career, not as many decades ago, the commms officer who speaks to the Tower was always on one of the decoy aircraft.
