It is impossible to help without knowing exactly what you are trying to monitor. There are conventional frequencies and trunked systems. If you are looking for TGID's, it is a trunked system. Without knowing which agencies you are trying to monitor, we are not able to provide a link to the system with the TGID's in the database. There are different types of trunked systems. The sites you use depend upon your location. You must have the correct frequencies entered into each site. It would help to know your friend's city and county to determine the best site or sites. The BCD396XT cannot receive P25 Phase 2, ProVoice, DMR, or NXDN. Conventional frequencies and talkgroups may be encrypted. There is no one-size-fits-all answer to your question.
