Strange system
The system is a Motorola Type II SMR system. My eyeballs have been watching the tgid's pop up on the bearcat for two months. Here are the tgid's Type I that normally come up. Block 0, 720 is the dispatch and the other people talking comes up on 704. This is a security company. I tried the status bits. It changed them to 721 dispatch and 713 other conversation. 6272 vs 6288 is the other oddball tgid's in the construction business. The tgid's in the Type II Catagory, 6160 never changes. Both coversations stay on same tgid. It is a tow truck company. 5712 is west side sanitation and 6096 is the eastside. 6480 is a another construction type business. Now block 4 Type I tgid's. 34880, 34896 and 34912. To monitor the whole conversation you need all 3 of these tgid's. Type II catagory. 36928 is a gas company. A another strange thing is that the local police use this system for a backup if there main system is down.
When they are using it as backup a tgid pops up and you hear a motorboat sound as if it was a control channel. You have to lock out the tgid with the motorboat going to hear the local pd. When you are monitoring them on backup its the exact tgid's they use on their main system. I don't know much about SMR 800MHz trunked systems but this one is hard to figure out. Any ideas?
