Ok, today I was updated on the rebanding in osceola and also clearified some info with the SO.
The only control channel being rebanded is 859.5375 and will be operational by June.
As for the the SO channels, the new tg 240 is the south district dispatch channel, East TTY is the primary TTY channel for the entire county, Each zone has a primary dispatch channel and a dedicated TTY however at this time only the following are used.
West Dispatch....784
West TTY ..........528
East Dispatch.....272
East TTY...........1296
South Dispatch ...240
South TTY Unknown and not in use
Also to be noted that Fire rescue will be switching to a new tone out system that is planned to go online by the end of march but more likely April. The normal two tone paging is supposed to go away and be replaced with VOIP system to each station.
