Well, the current old analog scanner I own now can still pick up everything within a Trunked System (it simply picks up every transmission made). Furthermore, someone sent me a PM and further explained it to me. Supposedly the bcd436 CAN pick up every transmission within a system (even tgs not in the database) IF it is set to scan with the ID search set to ON for each system you would like to hear any TG that may not be in the db. However, I would imagine that this would take it much longer to scan. I could be wrong though. Perhaps the scanning speed is ultra fast regardless.
