The TDFM-136 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 TDFM-136 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 must not be operated as a base station in Canada. 1.2DESCRIPTION The TDFM-136, Transceiver is a frequency agile, fully synthesized airborne transceiver capable of operating in the 136.000 MHz to 174.000 MHz frequency range in 2.5 kHz 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. The TDFM-136 Transceiver provides 150 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 in the TDFM-136, wideband (25 kHz analog) or narrowband (12.5 kHz analog) channel spacing assignment. The P25 mode (12.5 kHz digital) channels include both NAC and Talk Group capability. 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. 1.3PURPOSE OF EQUIPMENT The TDFM-136, 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. 1.4MODEL VARIATION There are four variations of the Model TDFM-136 Transceiver. All units offer identical features and performance except for the following differences: TDFM-136, P/N 981087-1GREEN display and 28 Volt back lighting. TDFM-136, P/N 981087-1 (5V)GREEN display and 5 Volt back lighting. TDFM-136, P/N 981087-2RED display and 28 Volt back ligting. 1-2 TDFM-136, P/N 981087-2 (5V)RED display and 5 Volt back lighting. Both P/N's 981087-1 and 981087-2 are always provided with 28 Volt back lighting unless a specific request is made for 5 Volt AC operation. 1.5TECHNICAL CHARACTERISTICS SpecificationCharacteristic GENERAL Model Designation:TDFM-136 Frequency Range:136.000 to 174.000 MHz Operating Modes:P25 CAI and conventional analog 12.5/25 kHz conventional analog 12 KB…
