SCANNER INFORMATION FOR EAST CENTRAL FLORIDA
To monitor the various public safety agencies (sheriff, police, fire, EMS, etc.) in
East Central Florida, you need to have a 800 MHz Trunk Tracker scanner.
It is almost impossible to monitor these trunked systems using and older, conventional type scanner.
Only a few agencies in this area are still communicating in conventional (non-trunked) mode.
In a conventional system each agency (police, fire, DPW etc.) has their own seperate frequency or group of frequencies.
Trunked Systems are computer-driven systems with anywhere from 5 to 28 frequencies that are shared by all
the county and city public safety departments.
The system is designed so that each conversation hops between these frequencies.
- When a user presses his microphone key, the system automatically transmits the call on the first available frequency.
- This means that every time a user keys his microphone, he could be on a different frequency.
- The original frequency that he was using will probably now have a different agency and conversation on it.
- Because of this it is difficult to listen to trunked systems using a regular scanner.
In a trunk system:
- One of the frequencies is the data (control) channel and will have a steady buzzing sound on it
- The data channel is transmitting the data that controls how the trunk system operates.
- Instead of assigning each agency a frequency, users of the system are assigned talkgroups.
- Talkgroups are setup so that each agency will only hear their own units and not all the communications on the system.
- Each radio is programmed with a different ID that is displayed to the dispatcher and other radios using the system when it transmits.
The following is a list of the trunked systems currently being used in East Central Florida.
M/A-COM EDACS TRUNKED SYSTEMS
Volusia County
Brevard County
Flagler County
Hillsborough County
Indian River County
Florida Power & Light
Orlando Utilities Commission
Notes:
- The frequencies must be entered into the scanner as they are listed on the webpage (LCN order).
- Only the Uniden and GRE EDACS scanners can follow the FP&L and OUC narrowband EDACS systems.
- Some Sheriff and police department talkgroups use ProVoice Digital mode and cannot be monitored by any scanner.
MOTOROLA TRUNKED SYSTEMS
Orange County City of Orlando
Osceola County City of Winter Park
Palm Beach County Disney Cruise Ships
Polk County Sea World
St. Lucie County Universal Studios
Seminole County Progress Energy
City of Lakeland Tampa Electric Company
City of Maitland Delta Airlines (Orlando)
City of Ocala Many business users
Notes:
- All Motorola systems in East Central Florida are Type II systems.
- Some scanners have a "Control Channel Only Mode" where you just have to enter the control channel to
monitor a Motorola Trunked System. All systems in this area use Plan 1 except for Polk County which
uses Plan 2.
- Motorola Trunked Systems are also used by business users (taxicabs, pest control, wreckers, repairmen etc.).
They are mostly in the 935 - 940 MHz business band.
LTR TRUNKED SYSTEMS
Ft. Pierce Utilities Authority
Mears Transportation
MV Transportation (Orlando Paratransit System)
Rinker Materials Corporation
Tarmac, Inc.
Florida Rock Industries
Orlando International Airport
University of Central Florida
Various business users
Notes:
- The frequencies must be entered into the scanner as they are listed on the webpage (LCN order).
- 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 to 20 seconds.
- LTR Trunked Systems are used by many business users all over Florida (security patrols, paratransit systems,
taxicabs, pest control, wreckers, sanitation trucks, repairmen, hotels & resorts etc.). They can be
found in the 400, 800 and 900 MHz business bands.

MISC. TRUNKED SYSTEMS / MODES
The following trunked systems/modes cannot be monitored by any type of scanner:
M/A-COM Pro-Voice Digital Trunked Systems (onwned by the State of Florida)
Both the control channel and all the talkgroups are encrypted.
The following agencies are using this system:
Florida Highway Patrol (including the Florida Turnpike)
Florida Fish & Wildlife Conservation Commission
Florida Department of Business Regulations
Florida Department of Law Enforcement
Florida Department of Corrections
Florida Department of Management Services
Florida Department of Transportation - Motor Carrier Enforcement
Florida Department of Juvenile Justice

Franklin County Sheriff's Office
Glades County Sheriff's Office
Gulf County Sheriff's Office
Levy County Sheriff's Office
Okaloosa County EMS
Union County
CSX Railroad Police
LTR Multinet Trunked Systems (used by Clay County)
NEXTEL iDEN Trunked Systems (used by Disney World)
EDACS ProVoice Digital Mode (used by some talkgroups for police undercover work)
Motorola Encrypted Mode (used by Orlando PD and some PAFB, City of Winter Park talkgroups)
220 mHz Passport LTR Systems (used by buisness users)
Notes:
- When a talkgroup is transmitted in the EDACS ProVoice Digital Mode, there is no indication on the
scanner, nothing is heard or seen on the display.
- Most police and fire departments also use NEXTEL to pass along sensitive information.

MISC. SCANNER INFO
Typical scanner receiving ranges:
A portable scanner can receive a trunked system up to 10 to 15 miles from the transmitting
antenna. A base scanner with an external antenna can receive a trunked system up to 15 to
25 miles from the transmitting antenna. These ranges depend on various conditions such as
scanner sensitivity, location and type of antenna used.
Always program in to the scanner the frequencies of the closest transmitter antenna to your
location.
Only the repeater output frequencies are listed on the website. Do not enter the repeater input
frequencies into the scanner.
One channel in each Motorola or EDACS trunk system is the control (data) channel. It will be
active all the time and sound like digital data (buzzing sound).
When a trunk tracker scanner is programmed correctly:
- You will no longer hear the system control (data) channel.
- Talkgroups will be displayed on the scanner display instead of frequencies.
CONVENTIONAL SCANNER INFO
If you have a older conventional scanner you can still listen to the following:
Florida Division of Forestry
Marine frequencies
Railroad frequencies
Aircraft frequencies
Most counties still page out fire stations on VHF.
Police intercity on 155.37 is very active in the Orlando area.
Lake County Sheriff, Police and Fire Departments still use VHF frequencies.
There are many buisness users, hotels, shopping malls etc. that use conventional VHF and UHF frequencies.
