I frequently talk with my son in Dallas, N1GAT and use call sign routing as he does when he calls me. The questions I have are: where is the information stored that is used for his radio to find which repeater I last transmitted? How long does it stay there? How long does it take to update?
I have noticed a couple of things. Sometimes when he calls me I am on one of our repeaters that is linked to a reflector so I try not to talk with him there. I usually go to our stand alone repeater, transmit there and then wait for him to call. However, sometimes he calls me before I have switch. So I tell him to wait, I switch repeaters and call him. On some occasions the switch is almost instantaneous and sometimes it takes a while. In fact one night I switched before he called and his call to me still went to the other repeater, not the one I had last transmitted on 30 minutes earlier.
