Your UBCT8 is tracks three major types of trunked radio systems. These systems are
described here.
- Including Type I, Type II, Hybrid, SMARTNET, and Privacy Plus.
Motorola systems are widely used by public safety and business users. Most are on
the 800 MHz band, and recent systems are appearing on other bands. (see page 43).
- Including "Wideband" 9600 baud and SCAT. "Wideband" systems are mostly on
the 800 MHz band, and are used by public safety, utilities, and business users. Some
systems are used on the VHF and UHF bands. (see page 39). SCAT systems are
single-channel EDACS systems.
- These systems are mostly for business users, and found on the UHF, 800 and 900
MHz bands. (See page 42).
For details on the operation and programming for all of these systems, see pages 29-47.
When tracking these types of systems, remember these important points:
Your scanner defaults to monitor Motorola Type II 800; however, you can change this if
the system in your area is different. (The types of systems are discussed below.)
Motorola, SMARTNET, and PRIVACY PLUS are trademarks of Motorola Inc. EDACS is a
registered trademark of the M/A - COM Inc. LTR is a registered trademark of E.F. Johnson
Company.
For trunked reception, a good setting for the control is in the
center of the range with the color marker pointing up. See the
illustration.
If it is set too high, it could prevent your scanner from locking to the
Control Channel reliably. If it is set too low, it will slightly delay finding
the Control Channel. The best setting is the same as for conventional
reception, and is critical for monitoring trunked systems.
