inexpensive consumer radios such as GMRS/FRS radios. 
The range is typically 1-8 miles, depending upon the 
terrain and many other factors. 

Repeater systems use two frequencies: one transmits 
from the radio to a central repeater; the other transmits 
from the repeater to other radios in the system. With a 
repeater-based system, the repeater is located on top of 
a tall building or on a radio tower that provides great 
visibility to the area of operation. When a user transmits 
(on an input frequency), the signal is picked up by the 
repeater and retransmitted (on an output frequency). 
The user’s radios always listen for activity on the output 
frequency and transmit on the input frequency. Since the 
repeater is located very high, there is a very large line of 
sight. 

Typical repeater systems provide coverage out to about a 
25-mile radius from the repeater location. 

Your BC246T is designed to track the following types of 
trunking systems.

• Motorola Type I, Type II, Type IIi, hybrid, SMARTNET, 

and PRIVACYPLUS analog trunking systems, which 
are extensively used in 800 MHz communication 
systems. 

• LTR trunking systems
• EDACS SCAT trunking systems
• EDACS trunking systems

When tracking these types of systems, you might want to 
remember these important points: 

• Your scanner can track more than one trunking 

system at a time and scan conventional and trunked 
systems at the same time.
