Thx

you don't...
any TG can use any freq. usually the TGs will use the freqs assigned to that site. the control channel tells the radios what to do. when a unit/dispatcher/whatever keys the mic, the system knows what TG they are on (like a channel), then the system assigns a freq. it doesn't matter what freq it is as long as it is for that site and is free.
imagine a busy office building with multiple companies. the building would be the site, the companies would be the agencies (PD, Animal Control, Fire, EMS), the people would be the TGs. they all report to the same building and use the same main doors to enter. there are say, 8 main doors. the people enter through these doors and report to the correct offices. when they come back from lunch or return the next day, they could use the same door but they could also use the other 7. it doesn't matter how they enter the building as long as they get to their offices on time.
if I'm off or wrong with my example, then please feel free to correct me. I hope this helps though.
"danstrainz", where are you and what scanner are you trying to use?
