Uniden UBCD396XT Edacs Systems, Conventional Systems, Non-scannable Systems, System Voice

UBCD396XT

∙Motorola VHF: all of the frequencies are between 100 and 200 MHz.

EDACS Systems

There are three subtypes of EDACS systems:

∙EDACS Wide: identified as EDACS Standard in the system type.

∙EDACS Narrow: identified as EDACS Narrowband in the system type.

∙EDACS SCAT: identified as EDACS Scat in the system type (these systems operate on a single frequency).

Conventional Systems

This fifth type of scannable system is a general catchall for all non-trunked systems. See section on Conventional Systems for more information.

Non-scannable Systems

There are several system types that cannot be monitored with a scanner, either because the systems use proprietary digital formats that are not licensable by scanner manufacturers, or because the systems are not in wide enough use to make it cost-effective for manufacturers to develop a scanner that can monitor them. These non-scannable systems are identified in the system type as:

∙LTR Passport

∙OpenSky Standard

∙MPT1327

∙Tetra

System Voice

System Voice summarizes the kinds of voice modulation used on the system. You’ll find the following voice types:

∙Analog (can be heard with any trunking scanner)

∙APCO-25 (can be heard with a digital scanner)

∙ProVoice (cannot be heard by any scanner)

∙VSELP (cannot be heard by any scanner)

The system voice also tells us when digital channels are mixed in with analog channels on the same system. Unfortunately, this means the system voice line can cause a lot of confusion. Just remember: system voice does not define the system type.
