While reading a blog regarding last night's police shooting (http://shavedlongcock.blogspot.com/2011/07/2-chicago-cops-shot-in-011th-district.html), the blogger, a CPD detective, reports tact teams switching to a secure 800 mhz channel or network. I assume he's not referring to the old trunked system because tact teams don't carry the STX radios compatible with the system. I would also think a detective know what's he's talking about, when he says that it's secure.
Does anyone have any ideas as to what frequencies those might be? I see that the OEMC has some non trunked 800 mhz frequencies licensed - 854.5875, 855.4375, 855.8625, and 855.9125, but those may be used by the CFD. Also, the City's 470 mhz license has some frequencies going as high as 481 mhz, in trunked and non trunked modes, so this may not be an 800 mhz frequency at all.
If anyone can monitor some of these, or perhaps has some inside information about new frequencies or radios, it would be appreciated.
