I think the information I contributed to the database here has the current UHF frequencies for Memphis Center. We don't work much military traffic that uses UHF in my area at ZME, so I don't have those frequencies committed to memory.
ZME sectors would be Elvis 33 UH (I work this one), Walnut Ridge (ARG) 35 UH (in the area next to me) and ZKC Blues UH 90. I can't recall what the UH sector to the west of Blues is, as it is well beyond my airspace.
