Yes right now, as CH 5 is one of the OLD freqs still in the line up from the original 4 chan Hi Band system (154.8300, 151.0700, 156.1500, 155.5050)
It is listed as a Base Station, and Mobiles. but is mainly a talk around/Car to Car freq right now. Once all the new stuff is fully integrated by mid 2005, the line up will be changed to its "permanent" setup till digital conversion. Lo Band 39.5000 will be left in for the time being as interop with MHP on the Tangi/Pike border, but plans are to phase it out completely, and a new patch set up using MS's Statewide Hi Band as the link freq when full changes take effect. I wil keep you all updated.
In other areas, such as the Concordia Parish/Adams County - MS River crossing, there are still no exact idea when a new Interop Freq will be chosen, and Lo band 39.5000 is still used for MHP-LSP.
