INSTALLATION APPROVAL NOTE
Presently, no TSO standard exists for airborne FM transceivers. To make it easier for installation
agencies to provide their customers with an approved installation supported by an effective Airworthiness
Approval, Technisonic has secured Supplemental Type Certificate (STC) Approvals on its Airborne FM
products for a limited number of airframes. The above referenced DO-16 G test data is also on file and
available from Technisonic to support approval requirements in airframes for which Technisonic does not
possess an STC.
Approved aircraft types are listed in the attachments to the formal STC documents. These STCs are the
exclusive property of Technisonic and require the written authority of Technisonic for their use. Letters of
permission are provided upon request. To assist Factory Authorized Technisonic Dealers in the
certification process, we have placed copies of our STCs on our website. These documents may be
downloaded and used as support for the technical submission to FAA or Transport Canada. Only
authorized factory dealers/installers are permitted to download and make use of these documents on
behalf of their customers (end users) in support of regulatory agency approval. Please refer to the
Technisonic website www.til.ca for the latest issue of available STCs.

1.1 INTRODUCTION
This publication provides operating information on the TDFM-93 airborne transceiver. The
exact configuration depends on which and how many RF modules are installed.
1.2 DESCRIPTION
The TDFM-93 transceiver is an airborne multi-band radio capable of operation in conventional
analog FM, AM, P25 digital FM systems, SmartNet/SmartZone trunking systems, and P25 96
trunking systems. RF modules are available in single, dual or tri bands that support various
combinations of VHF LO, VHF AM, VHF FM, UHF-LO, UHF-HI, UHF AM and 7 -8 MHz
bands. Up to 4 single or multiple band P25 digital modules and one analog only module can be
supported.
These optional additional features include P25 96 trunking Phase 1 and 2 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-93 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 for each band. FPP is available on all bands of modules.
The TDFM-93 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. Analog only
modules support CTCSS, DCS, wide, and narrow band operation where applicable.
TDFM-93 transcievers with MOD 14 (MCP) have the capability to provide PTT, mic and
headset for up to 2 (bands 7 and 8) remote handheld transceivers and/or a Latitude Technologies
S2 -P12 satphone / PTT network com transceiver. Front panel control of the S2 -P12 is
provided via the display and keypad. Connector J9 provides the MOD 14 interface. See table 6
for a list of recommended interface cables for various hand held transceivers. A digital audio port
has been added to interface with the Technisonic TDAP-65 and TDAP-75 digital audio panels.

2.1 GENERAL
This section contains information and instructions for the correct installation of the TDFM-93
Transceiver.
2.2 EQUIPMENT PACKING LOG
Unpack the equipment and check for any damage that may have occurred during transit. Save
the original shipping container for returns due to damage or warranty claims. Check that each
item on the packing slip has been shipped in the container.
2.3 INSTALLATION
The TDFM-93 Transceiver is designed to be Dzus mounted and should be installed in
conjunction with an IN-93 installation kit. See Figure 1 for an outline drawing of the unit with
dimensions to facilitate the installation.
2.4 INSTALLATION KIT – CONTENTS
The IN-93 installation kit (P/N 129292) consists of:
1. One 25-Pin Cannon D mating connector (female) complete with crimp pins and hood.
2. Two 15-Pin HD Cannon D mating connector (female) complete with crimp pins and hood.
3. One 15-Pin HD Cannon D mating connector (male) complete with crimp pins and hood.
4. One 26-Pin HD Cannon D mating connector (female) complete with pins and hood.
5. 5 BNC connectors.
2.5 ANTENNA INSTALLATION
The type and number of antennas depends on the model of transceiver being installed. The
