If you are monitoring a Talk Group that has no activity, there are several possible causes. The TG may not have any active users in the local area. Trunked systems can isolate the areas where their transmissions can be received by where the active transceivers are located. Another possibility is that many agencies are migrating to newer radio systems. We have displayed many of the TG’s that are planed for future use. As the systems become active, the TG will start receiving broadcasts.
