[TrunkCom] IL: Casino Queen TRS solution

[Todd Hartzel]

Greetings all,
        Here is my solution for those that monitor the
Casino Queen TRS in East St Louis, Illinois.  

Motorola ID:  7508 
Frequencies:
- 851.0125
- 852.4625
- 852-4875

System:  Type I, Motorola
Fleetmap:  b0, b4, b5, b6, b7 = S-0
                 b1 = S-4 ; b2 = S-12

Talkgroups:
100-1 - Jackpot reporting
100-3 - Jackpot reporting (not in current use)
200-1 - Ch A (Security)
200-2 - Cb B (Security)
200-8 - Ch H (Janitorial)

Block #2 has been a tough one.  I have tinkered
with all of the Size Codes.  SIze Code S-12 seems
to be the best fit.  This system starts fleets with 
even-numbers (10x-1, 20x-1, etc).  Block #1 was
easy.  200-1 & 200-2 are the primary users on the
system.  Very busy.  200-8 users fall within Block
#3.  Size Codes S-13 & S-14 will not work, because
I have determined 200-1 & 200-2 to be completely
independent talkgroups using BC-235'x ID Search 
Mode (Holding down 'SEARCH' til it beeps twice.  
So that all active IDs flash on the screen.  

If I use S-4, Ch A (200-1) appears on 200-3.  Ch B
(200-2) appears on 200-4.  If I use any size code with
a lower IDs count, the users of 200-1 appear on 
sperate talkgroups (during breaks in the conversation).
Same thing for the users on 200-2.  So we can rule out
all others:  S-1, S-2, S-3, S-5, S-6, S-7, S-8, S-9, S-10
& S-11.  S-4 & S-12 are the only two that correctly keep 
the users on the talkgroup ID.  S-12 is my best guess at
a solution.
