Speculation on my part...
The West Dispatch, East Dispatch, and North Dispatch talkgroups are going to be "strictly" dispatch only TG's....there should not be any chit chat or fire operations on those talkgroups. The idea is that incidents will be dispatched on the Dispatch TG's, but the actual response will be assigned to a TAC TG. In this plan, the conventional frequencies will not be patched to any of the dispatch TG's, because they do not want to tie up the dispatch channels with field response traffic.
Keeping in line with that philosophy, I can only *assume* that the 800mhz Tac channels were patched to the 154.385 and 154.430 frequencies so that outside agencies responding with either Everett Fire or Marysville Fire will be able to talk directly to those agencies - without tying up their Dispatch TG's.
Just like with SNOCOM now. I'm listening to TG 5424/TAC-21. It appears to be fully patched to 154.010. So, when SNOCOM begins to dispatch units on 800mhz, they will receive the dispatch on 800mhz (Disp 5)- and, the response will be on TAC-21/154.010. In that way, units from outside SNOCOM who respond to assist (or, SNOCOM units that haven't been completely converted over to 800mhz yet) will still be able to operate together - and not tie up the DP Talkgroup.
Clear as mud?
Brad.
