This system is currently going on line in Lewis and Clark County as a Test Bed for what will eventually be the Montana Statewide APCO 25 Trunked System. Most local, county, and state law enforcement agencies will be operating on this system. The Lewis and Clark County system will include Lewis and Clark County Sheriff, Helena Police Department, East Helena Police Department, and various Montana Highway Patrol units. It will eventually be expanded to cover the entire state.
The Lewis and Clark County System consists of 5 tower sites with 3 or more VHF channels in use at each.

Site 6 may not currently be in the trunked system but is scheduled to be.

Stonewall will have a 1 channel P-25 Analog/Conventional Repeater. It will be taled to from the Belmont site that will have a remote base on this channel connected to it's 3 channel trunk system.
Sunset will be a 3 channel trunked P-25

Augusta will be a 1 channel P-25 analog/conventional repeater. It will be talked to from a remote base located on Sunset and tied into the sunset trunked system/microwave.

Hedges will also be a stand alone repeater with a remote base from Hogback talking to it.

The Uniden radios capable of monitoring this system will obtain table data directly from the data stream. RS Pro-96/2096 will need to set the custom multi-table setting as follows:

GRE/Radio Shack Table:
ChLo  ChHi  Offset Base       Step  Bank
08192 12287 08192  149.05000  05.0   2
12288 16383 12288  136.00000  10.0   3
16384 20479 16384  136.00500  10.0   4
20480 24575 20480  149.05000  05.0   5
24576 28671 24576  149.05000  05.0   6
28672 32767 28672  146.00500  05.0   7
32678 36863 32678  136.00500  10.0   8
36864 40959 36864  136.00000  12.5   9
40960 45055 40960  145.37500  05.0   10
45056 49151 45056  144.11000  05.0   11
49152 53247 49152  136.00500  10.0   12
53248 57343 53248  149.05000  05.0   13
57344 61439 57344  136.00500  10.0   14
61440 65535 61440  149.05000  05.0   15

Please note that you can only load 6 sets of setting per table in the RS so you must group your sites based on what tables are used at that/those sites per bank according to how you want to arrange your scanner. The banks used at any site will be in the comments of that site.

Custom Uniden Frequency Tables 
 	    1	     2	       3
Base:	  151.0100  158.7300  161.0100
Spacing: 15.0     15.0      15.0 
Offset:   380 	    579       632

These tables will require futher modifications for correct tuning.
