NOTE
Daniels Electonics Ltd. utilizes a three-level revision system. This system
enables Daniels to identify the significance of a revision. Each element
of the revision number signifies the scope of change as described in the
diagram below.
DOCUMENT REVISION
DEFINITION
Major Revisions: The result of a major
change to product function, process or
requirements.
Minor Revisions: The result of a
minor change to product, process or
requirements.
Editorial Revisions: The result of typing
corrections or changes in formatting,
grammar or wording.
1-0-0
Three-level revision numbers start at 1-0-0 for the first release. The
appropriate element of the revision number is incremented by 1 for each
subsequent revision, causing any digits to the right to be reset to 0.
For example:
If the current revision = 2-1-1 Then the next major revision = 3-0-0
If the current revision = 4-3-1 Then the next minor revision = 4-4-0
If the current revision = 3-2-2 Then the next editorial revision = 3-2-3

Chapter 1: Introduction 1
User
Guide
This document is written as an introduction to Daniels Electronics Ltd.
P25 Radio Systems. The document assumes the reader is familiar
with conventional Two-Way Radio Communications systems.
Project 25 is a standards initiative, to be amended, revised, and added
to as the users identify issues, and as experience is gained.
DANIELS MODEL NUMBERS
Daniels Electronics Ltd. has manufactured radio systems for more
than 50 years. In the early years, Daniels manufactured AM and
SSB radiotelephones for the marine industry, and more recently,
the MT series of radios for mountain top repeaters and base station
applications.
MT-2
The MT-2 series of radio modules were originally manufactured in the
1980’s. This radio series was a crystal controlled analog radio system
capable of wideband (25 KHz) operation. Although systems are still in
operation throughout North America, this series of radio modules was
discontinued in the 1990’s and is no longer supported.
MT-3
The MT-3 series of radio modules were originally manufactured in
the early 1990’s. This radio series was available with both crystal
controlled and synthesized analog radio modules capable of wideband
(25 KHz) or narrowband (12.5 KHz) operation. The MT-3 radio series
is manufactured and sold for use throughout North America and the
world. The crystal products have been discontinued.

MT-4
The MT-4 series of radio modules entered production during 2001.
This radio series is the P25 compliant digital narrowband radio
system, capable of analog (wideband and narrowband) or P25 digital
operation.
Daniels Electronics is committed to continually improving and
enhancing our product line. As the MT-4 P25 products evolve, the
hardware, firmware and software of the radio modules change. In order
to define these changes, the MT-4 product line is further described
as:
MT-4R
The MT-4R series of P25 radios were manufactured from 2001 until
the end of 2003.
MT-4D
The MT-4D series of P25 radios are the current line of P25 modules.
MT-4E
The MT-4E series is a future generation of P25 modules.
DIFFERENCES BETWEEN MT-4 SERIES
MODULES
The MT-4R and MT-4D modules are basically identical in operation, with
some advancements taking place in the RSS software programming
for the MT-4D (such as the ability to software program the squelch tail
on/off and timer). The only significant difference between the MT-4R
and MT-4D is in the transmitter modules. The MT-4R transmitter was
not capable of being programmed for mixed mode operation. Mixed
mode is the ability for one transmitter channel to operate on either
analog or digital, based on the received signal. In order to simulate
mixed mode, the MT-4R transmitter was programmed with Bank A
as the analog channels and Bank B as the digital channels, and the
received signal simply switched between Bank A and B. The MT-4D is
capable of mixed mode, so Bank A and B can be programmed in either
analog or digital operation.
A P25 system can be comprised of both MT-4R and MT-4D modules.
For example; an MT-4R receiver and MT-4D transmitter can be used
to create a repeater, or an MT-4D link pair can be added to an MT-4R
repeater.
