Well yes they may affiliate with another tower, but at all times the control center is affiliated with the downtown site, 21904 will always
appear on that site, no matter where the helo is. BTW, it was mentioned before about the AM frequency (128.8500) and that really should be listened to if you are not "out in the sticks", as other medical air transport aircraft use that to communicate with Herman either inbound or outbound.
