I am trying to get a handle on the TXwarn system. I live in the Katy area and have the Clodine tower programmed in my 346xt. I can hear everything(SO, Fire, EMS) without any issues. I thought that if you program in the other towers frequncies in to a separate "site" i could follow the katy area traffic using the Medical center tower and my Katy area Group ID(or ID search). I've prgrammed in the frequncies for the medical center but dont get any radio traffic ever. Any ideas what i am doing wrong or does the TX warn system not work that way? Thanks for the help in advance.
