29616 Ch. 82 TAC 11 is probably the one you want. Typically they use the TAC channel "nearest" their dispatch channel in the channel line-up. Many times they'll use the phrase "go up one" or "go down one" or "go to 82" to refer to the tac channel. Don't rule out them using some other method of communication, like mobile phone, for BS. Use of the tac channels in the upstate is moderate at best, not at all extensive.
