793.1875?

[cpd204]

I have been searching the 700 MHz band and been picking up 793.1875 or .90625 with a CTCSS tone of 127.3 they responded to one call in Calumet City so it might be there. I'm also thinking it might be an image frequency (or something like that) of 856.2125. But I also hear business or public safety higher in 794-796 it isn't digital or a TRS since I don't have a digital trunking radio scanner. Anybody know what it is?

I have confirmed that 793.1875 (or .90625) is an image frequency of 856.2125 which the dispatch for Cal City
But now I'm not sure if all of the frequencies in 793-796 are image frequencies of the 800 band.

The mobile/input part of the band is 776-806 MHz so any base stations, repeaters or control channels you hear there would be images or intermod. The base/output part is 746-776.
