STC APPROV A L S

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
(both US and Canadian) on it’s airborne FM products for many helicopters currently being
delivered in the US and Canada, as well as a number of single engine fixed wing aircraft. The DO­160C test data, referenced below, are 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 STC’s
are the exclusive property of Technisonic Industries Ltd., and require the written authority of
Technisonic for their use. To assist Factory Authorized Technisonic Dealers in the certification
process, we have placed copies of our Canadian and US STC’s on our web site along with a letter
of authorization for their use. These documents may be downloaded and used as support for the
technical submission to FAA or Transport Canada. Only factory authorized 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 web site www.til.ca for
the latest issue of available STC’s and letter of authorization for use.

GENERAL D E S C R I P T I O N

1.1 Introduction

This publication provides operating and installation information for the TDFM-136B, Digital
Transceiver manufactured by Technisonic Industries Limited. The TDFM-136B is Project
25 (P25), Phase 1 compliant. The unit offers digital or conventional analog FM
communications over an extended frequency range with selectable channel spacing and is
intended for use (in the U.S.) only by government agencies or contractors thereto, who
have obtained licensing for operation in the 136-150 MHz portion of the band. If the TDFM­136B transceiver is used in CANADA, operation is restricted to the following sub bands:
138-144, 148-148.99, 149.005-150.005 and 150.05-174 MHz. Furthermore the frequency
agile transceiver is restricted to airborne use and must not be operated as a base station in
Canada.

1.2 Description

The TDFM-136B, Transceiver is a frequency agile, fully synthesized airborne transceiver
capable of operating in the 136.000 MHz to 174.000 MHz frequency range in 2.5kHz
increments with either 25 kHz analog, 12.5 kHz analog channel spacing and P25, 12.5 kHz
digital modulation on a channel by channel basis. The Transceiver can operate without
restriction on any split frequency pair in the band and also incorporates a two channel
synthesized guard receiver.

SECTION 1

The TDFM-136B Transceiver provides 230 operator accessible memory positions. Each of
which is capable of storing Scan List membership information, up to eight (8) character
alphanumeric identifier, and Operating Mode information. In addition each memory position
contains information for both transmit and receive including: frequency, CTCSS tone, DCS
(DPL) code, P25 TalkGroup, and P25 Network Access Code (NAC) information.

Channel operating parameters, including frequency and other related data, are presented
on a 48 character, two line LED matrix display. Data entry and function control takes place
via a 12 button keypad.

1.3 Purpose of Equipment

The TDFM-136B, Digital VHF/FM Transceiver is designed to provide secondary airborne
communications to facilitate operations which are typically performed in a low altitude
environment. The transmitter section of this unit has a minimum of 8 watts and does not
exceed 10 watts output power, which may be reduced by a front panel switch to 1 watt, in
order to reduce interference to land based systems.
