Do Whistler / GRE scanners do proper trunktracking of LTR talkgroups, or do they just conventionally scan the frequencies and search for talk groups?
It's been a couple of years since I have messed with trying to monitor LTR systems, but I believe it checks all frequencies for activity and then checks the low speed data for the correct talkgroup. It also uses the same low speed data to figure out if the channel has the correct LCN as programmed.Let's say you hold an an LTR talk group. What does the GRE / Whistler scanner do to track it? Conventionally scanning every frequency to check if the talk group is active somewhere? Or, monitor the home channel and knowing right away which LCN to jump to if the talk group you're holding on becomes active?
