[TrunkCom] PGH TRUNKED SYSTEM FLEETMAP

[Rich Newbould]

I have been researching the Pgh trunked radio system.  To try to 
determine the correct fleetmap to program to properly receive the 
system.  I started with the info regarding Heinz field on the WPA page. 
 These talkgroup IDS cannot be Type II as there are only 16 numbers 
between each group, a true type II system will be spaced at 32 between 
each valid talkgroup.  Also I would hear the same conversation taking 
place on  53632 and 53616  this should not be.    

I then set my scanner to type II and started capturing talkgroups (tgs) 
from the entire system.  After collecting this data for 2 weeks I 
imported it to Excel and used the fleet map conversion utility which is 
available on the web. After reviewing the data in the conversion utility 
I came up with the following fleet map.  It may not be correct but it 
should be real close.  Please try it and let me know the results you get.

Block 0  S12
Block 2  S12
Block 4  not used or unknown at this time
Block 5 S-4
Block 6 S-1
Block 7 S-4

Note B1 and 3 are not shown because S12 uses 2 blocks so there really is 
no block 1 or 3 after entering the S12

Please submit any info you come up with,  I will be making changes to 
this fleetmap and posting them as I continue to explore.
