SECTION 1 - GENERAL DESCRIPTION
1.1 INTRODUCTION
This publication provides operating and installation information on the TDFM-7300 airborne
transceiver. The exact configuration depends on which and how many RF modules are
installed.
1.2 DESCRIPTION
The TDFM-7300 transceiver is an airborne multi-band radio capable of operation in
conventional analog and P25 digital FM systems, SmartNet/SMART ZONE trunking systems
and P25 9600 trunking systems. Type II RF modules are available in VHF, UHF LO, UHF HI
and 700/800 MHz bands.
These optional additional features include P25 9600 Baud trunking that may be combined
with AES and/or DES-OFB encryption with OTAR in any of the available modules.
Bands 1 through 4 on the TDFM-7300 are not normally frequency agile. In order to have the
ability to change the frequencies at the front panel, the FPP (front panel programming)
option must be ordered. FPP is only available on the VHF and UHF modules. The FPP option
precludes trunking and limits available channels to 240 (15 zones/16 channels) on that
module instead of 1000 channels. Please note that all 240 memories must be filled if FPP is
ordered.
The TDFM-7300 has provisions for four of the above RF modules as well as one analog only
module. This additional module is fully frequency programmable from the front panel. FM
only modules support CTCSS, DCS, FM wide and narrow band operation. FM bands
available are VLO, VLO2, VHF and UHF.
1.3 MODEL VARIATION
Irrespective of digital module type the bands are numbered 1, 4, 5 and 8 for VHF, UHF low,
UHF Hi and 800/700 respectively. The transceivers part number indicates whether type I (-
1, -2) or type II (-3, -4) modules are installed along with which type of modules are
installed. The front panel LED display will also indicate which type of modules the
transceiver contains.
The analog modules available include VHF Lo-band = 30-50 MHz, VHF Lo 2 = 66-88 MHz,
VHF High = 136-174 MHz, UHF = 403-512 MHz, UHF/AM = 225-400 MHz and VHF/AM
= 118-138 MHz.
A letter in the TDFM-7300’s part number represents each of these analog modules.
See examples below for clarification.
e.g. L= 30-50 MHz, H= 66-88 MHz, V=136-174 MHz, U=403-512 MHz, M= 225-400
MHz and A=118-138 MHz.
