  I knew I saw something about this on the LISR board; and I was right.
Mike Burnett posted this back in Feb, and it seems to have a bit more data
than the Trunkedradio.net listing.  Question is, which one is right?
---------------------
  In addition to my long-winded "Correction to Baltimore County" I have
also noticed that the MTA frequencies are listed incorrectly. (I think I
started into this one somewhere else...) The MTA uses a UHF Type II
Securenet Trunking System that has 9 frequencies. They are as follows: 
                                  
Base Frequency: 494.000 MHz 
System Offset: 12.5 KHz 
                                
494.3375 
494.4375 
494.6125 
494.6375 
494.8125 
494.9625 
495.0375 
495.1625 
                                  
    494.7625 is the Transit Police dispatch frequency and is NOT part of
the trunking system (its conventional). The Talkgroup ID's I have found so
far are as follows:
1712 - Bus Dispatcher 
1904 - Bus Dispatcher 
1936 - Bus Dispatcher 
1968 - Bus Dispatcher 
2000 - Bus Dispatcher 
1680 - Access Vans - Dispatch (Handicap bus) 
2128 - Supervisors - Dispatch 
2384 - Supervisors - Talkaround 
2032 - Supervisors - Bus consult patch 
2064 - Supervisors - Bus consult patch 
2448 - Telecomm Office - Radio Maintenence 
2512 - Vehicle Maintenence/Engeneering 
2480 - Vehicle Systems Engeneering 
1744 - Light Rail Control - South 
1776 - Light Rail Control - Central 
1808 - Light Rail Control - North 
                                  
  In addition the Light Rail trains still use the old VHF rail frequecies
which are correctly listed except for the police one.
