CENTRAL FLORIDA 800/900 MHZ LTR TRUNKED SYSTEMS

NOTES
The frequencies with channel numbers are in LCN order and must be entered into the scanner in this
order. Channels not listed must be left blank.

              Example:
               Ch.   Frequency
                1    blank
                2    blank
                3    blank
                4    blank
                5    blank
                6    blank
                7    blank
                8    936.4750

Logic Trunked Radio (LTR) Trunk Systems do not have a control channel such as Motorola or Ericsson
Trunked Systems. On a LTR Trunk System a data burst can be heard on each frequency of the system around
every 10 seconds.

Each user is assigned a home channel. A users talkgroup ID consists of an Area Code, a Home Channel and
a User ID. If the system is not very busy, then all conversations can be heard on the home channel. When
the system starts getting busy, one or more of the users will change over to another free home channel
frequency or one of the overflow channel frequencies. Overflow channels have no assigned users.

              Example:
              0-08-001
                0 = Area Code (0 or 1)
               08 = Home Channel (01 to 20)
              001 = User ID (000 to 254)

The systems listed above have their home channels and frequencies listed. The frequencies listed without
channel numbers are the overflow frequencies and still need their channel numbers figured out. Each system
can have a maximum of 20 channels.

Most LTR Trunked Systems are PassPort (LTR-Net) enabled. This allows multiple sites to be linked together.
Example: A Taxicab leaving Melbourne to Orlando can switch to one of the Orlando Systems after it gets out
of the range of the Melbourne system and it will be linked back to Melbourne.

These systems are used by Taxicabs, pest control, wreckers, repairmen etc. The system owners lease air time
to individual business users. The individual users do not need a separate license, only the system owner
needs a license. Because of this the only way of finding out who is using these systems is by monitoring
them.

Digital Packet Data talkgroups are used to send computer information that can contain vehicle location,
status or any other type of digital information. All that can be heard on these talkgroups is bursts of
digital data.

You can only enter one LTR Trunk System per bank.

Only the repeater output frequencies are listed. The repeater input frequencies are 39.00 MHz lower.
