[TrunkCom] Trunk-tracking Help

[Scott Baldwin]

Hello to the list.

I'm trying to set up my BC-245 and BC-895 to track the trunking system at 
the Vacaville CMF Prison site.  Their frequencies are 857-860.2625.

I started off in E2 mode, and noticed the ID's changed between radio 
users.  So I assume it to be a Type-1 system.  Setting it in E1 Mode, I 
chose S-14 as my size.  Even though this is an unusual size, I chose it 
because I had caught traffic with an ID of 37217 and the reply came back on 
34135.

Using the method of lowest ID and highest ID, the difference is 3082, 
meaning at least THAT many users used block 4.  Since S-13 has a max of 
2048 users, and S-14 is the next with 4096 users, for this reason I chose S-14.

Now here's my problem.  I was monitoring the other day and a call came out 
with an ID of 000-9 and a reply came back on 000-8.  It was the same 
conversation.  My BC-245 was still set on E2, and I noted ID 38374 and 
34267, respectively.  The problem as you can see is that the number of IDS 
(difference between the two) is 4107.  This exceeds the max of 4096 as used 
for a Type 1.

Does anyone know what kind of system this is, if it's not Type-1 or 
Type-2?  I have tried Edacs and LTR, but I either don't know how to set 
these systems up in my scanner, or they're not that either, as I've tried 
programming them in, but they don't track at all.  It's as if they don't 
see the control channel.

Thanks in advance.
