GENERAL DESCRIPTION
1.1 INTRODUCTION
This publication provides operating and installation information on the TDFM-600/6000 series airborne
transceiver. The exact model number depends on which and how many RF modules are installed.
1.2 DESCRIPTION
The TDFM-600/6000 series of transceivers are airborne multi-band radios capable of operation in conventional
analog and P25 digital FM systems, SmartNet/SMART ZONE trunking systems and P25 9600 trunking systems.
Type I RF modules are available in VHF, UHFLO, UHFHI and 800 MHz bands. Type II RF modules support
additional optional features not available in type I modules and are currently available in VHF, UHFLO and
700/800 MHz.
These optional additional features include P25 9600 trunking that may be combined with AES and/or DES-OFB
encryption with OTAR in any of the available modules. The factory will only produce radios with all modules of
the type I or type II configuration since different Motorola CPS programming software is required for each type
of module.
It may be possible to retrofit existing type I transceivers with one or more type II modules to support optional
features not available on type I modules. Contact Technisonic for details.
Irrespective of module type the bands are numbered 1, 4, 5 and 8 respectively. The front panel LED display
indicates whether type I or II modules are present upon radio start-up. The transceiver’s part number will also
indicate which type of modules it contains. Please see section 1.3 on Model Variation below for details.
The following are typical model examples:
TDFM-655 - Two UHF high band modules
TDFM-688 - Two 800 MHz modules
TDFM-6148 - One VHF, UHF low and 800 MHz module
TDFM-6158 - One VHF, UHF high and 800 MHz module
Module numbers are always specified in ascending numerical order. ie/ TDFM-6814 is not available.
The one exception to this numbering scheme is the model TDFM-636 which is a VHF transceiver with two type
II VHF modules and a 10 watt RF amplifier for each module.
1.3 MODEL VARIATION
There are several variations of the Model TDFM-600/6000 Transceiver. Each variation offers different
features and performance based on the type of RF modules and options installed.
