800 MHz conventional

I know for my area 868.400 is used once in a while. but i have all programmed seperate from the trunked systems.
bneilson lists 868.400 as both a simplex and a state repeater frequency. Do you know which it is in your area, Enos? Brett, where did you get that list?
I looked up some of these 800 MHz frequencies in the FCC DB, and they are licensed to Utah State in SLC rather than in the indivicual counties. The map of state repeaters I recently posted at
http://www.radioreference.com/data/images/a/4023/USRS.gif shows a 800 MHz conventional repeater in Carbon County and several other counties, but no frequencies are given in the SCIP document where I got the map (and no real clues from the FCC licenses).
At the meeting I attended last month Jerry mentioned 800 MHz repeaters at Little Sahara and in Summit County, but so far he hasn't provided the details I asked him for.
I'd like to enter the 800 MHz repeaters and simplex frequencies in the DB, but I don't know what is used where. Can anyone help out?

P.S. Here are some relevant quotes from the 2007 SCIP document:
"Regions outside the Wasatch Front area primarily utilize conventional technology in the VHF 150 – 174 MHz spectrum for wireless voice communications. The state provides 800 MHz analog conventional radio coverage in limited areas of the same region for purposes of interoperability between 800 MHz and VHF systems." (p. 26)
"Spectrum congestion in the VHF spectrum combined with the inability to secure additional frequencies required for system expansion compounds an ever increasing interoperability problem in the state. This is especially true near population centers where existing spectrum resources are already overloaded. The state provides limited 800 MHz conventional analog radio coverage in select rural areas, but fails to provide enough coverage for acceptable interoperability with agencies traveling to rural areas of the state from the Wasatch Front region." (p. 27)
The Murray Police Department and Murray City Fire Department are listed as using a "800 MHz Analog Conventional" system. (pp. 31-32)
The Unitah Region lists "800 MHz Analog Conventional (Voice)", "6 Channels in use (700 MHz)", "4 Channels in Use (800 MHz)". (p. 36) The Six County Region (west central Utah) lists "800 MHz Analog Conventional (Voice)", "6 Channels in use (700 MHz)", "2 Channels in Use (800 MHz Analog Conventional)" as well as UCAN. (p. 37) [Several other regions list similar information.]
"The SRS also provides limited 800 MHz conventional analog coverage outside the UCAN network footprint to facilitate interoperability between 800 MHz and VHF statewide. Existing 800 MHz conventional coverage outside the UCAN network footprint is inadequate for statewide interoperability requirements." (p. 46)
"Salt Lake City [TRS] and Murray City [Conventional] are the only cities within the UCAN network footprint today that continue to operate independent 800 MHz radio communications systems." (p. 50-51) [They seem to be forgetting the Provo/BYU system.]
"Meanwhile the Utah Department of Technology Services in partnership with the Utah Department of Public Safety has undertaken the task of expanding conventional analog 800 MHz coverage into rural areas of the state in a limited fashion. Statewide interoperability between existing conventional VHF 150 MHz and 800 MHz systems cannot be achieved without expanding 800 MHz coverage into regions where it currently does not exist." (p. 51)
