SECTION 1 - GENERAL DESCRIPTION
1.1 INTRODUCTION
This publication provides operating and installation information on the TFM-30 transceiver
manufactured by Technisonic Industries Limited. Standard factory software installed in the
TFM-30s is L(x). The unit offers an extended frequency range with selectable channel
spacing and is intended for use only by government agencies or contractors thereto, who
have obtained licensing for operation in the 30-50 MHz band.
1.2 DESCRIPTION
The TFM-30 transceiver is a frequency agile, fully synthesized airborne transceiver capable
of operating in the 30.000 MHz to 50.000 MHz frequency range in 2.5 kHz increments with
either 25 kHz, 20 kHz or 12.5 kHz channel spacing. The Transceiver can operate without
restriction on any split frequency pair in the band and also incorporates a two channel
synthesized guard receiver.
The TFM-30 Transceiver provides 120 operator accessible memory positions, each of which
is capable of storing a transmit frequency, receive frequency, transmit frequency CTCSS
tone or DPL code, receive frequency CTCSS tone or DPL code, an alphanumeric identifier
for each channel and wideband (25, 20 kHz) or narrowband (12.5 kHz) channel spacing
assignment.
Operating frequency and other related data are presented on a 48-character, two-line LED
matrix display. Data entry and function control are performed via a 12-button keypad.
Preset channels may also be scrolled and scanned through keypad function activation. Data
may also be entered via a PC computer with the provided software and optional PIB-100
programming interface box or via an older computer and PC Up/download cable, P/N

1.3 PURPOSE OF EQUIPMENT
The TFM-30 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.
1.4 MODEL VARIATION
There are four variations of the Model TFM-30 Transceiver. All units offer identical features
and performance except for the following differences:
TFM-30, P/N 961082-1
GREEN display and 28 volts back lighting.
TFM-30, P/N 961082-1 (5V)
GREEN display and 5 volts back lighting.
TFM-30, P/N 961082-2
RED display and 28-volts back lighting.
TFM-30, P/N 961082-2 (5V)
RED display and 5-volts back lighting.
Both P/N's 961082-1 and 961082-2 are always provided with 28 Volt back lighting unless
a specific request is made for 5 Volt AC operation.
