The TDFM-136A 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-136A 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-136A, 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-136A 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-136A, 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.

This section is divided into subsections as follows: 2.1 command structure overview and terms 2.2, 2.3, 2.4 and 2.5 detailed command descriptions by level 2.6 detailed operating description 2.1 COMMAND METHODOLOGY This section describes how the TDFM-136A command structure is organized. Command Levels In order to accommodate the necessary commands, the commands have been divided into different levels, each command level has up to 12 commands numbered 0-9, # and *; the zero (0), and the ESC (*) key are functions for every level, they allow the user to move between levels as follows: step up through command levels step down through command levels When stepping through command levels, the indicated level is shown in subscript in the 4th character position on the lower line of the display. Note that this display position is left blank for the default level (level1). Table 2-1 shows the command levels and the associated display character. Table 2 Command Levels COMMAND LEVEL DISPLAY Command/Operator L1 blank Command/Operator L2 2 Command/Operator L3 3 Command/Maintenance L4 4 Figure 2-1 below shows the front panel display for different Command levels. 0 0 1 M a i n D 1 3 4 . 0 0 0 0 R g G D 2 3 G u a r d 2 w 1 7 4 0 0 0 0 R t FIGURE 2-1 User Screen showing the Command Level Display Position In addition to the 3-operator available command levels, the unit can be put into a mode that allows access for Maintenance. This 4th command level (L4) allows authorized personnel to set operating policy for the radio through the use of 'Permissions'. These are explained in section 2-8. This command level should NEVER be enabled in flight. In order to restrict access to the Command/Maintenance Level 4, the side cover must be removed, and a maintenance jumper must be installed on the MCU board (see Figure 2-33).
TECHNISONIC INDUSTRIES LIMITED www.til.ca TDFM-136A Operating Instructions Page 2-2 TiL 09RE405 Command Types There are two basic command types: Inherent and Edit. An Inherent command is one that requires no additional input from the user, such as the ‘memory brightness’ or ‘scroll memory’ commands. An Edit command requires further input from the user. Command Scope The Main or the Guard Channel can be affected by most, but not all, edit commands. The channel to be edited depends on the position of the MN/GD and the G1/G2 front panel switches. In this manual, the scope of the command is given on the command title line as follows: (MN/GD) for a command that is valid in both Main and Guard, (MN) for a command that is valid for Main only Blank for a command that is not subject to channel restrictions. Command Conventions After selecting the command, the system expects further input from the user. All edit commands may be terminated in the same way: accept the entry and return abandon the entry and exit The commands that allow the user to choose an option from a list will always use the up/down arrows (key 2 and key 8 to step UP and DOWN respectively through the available choices). In addition, the key that was used to enter the function can be used to step UP through the available choices. Example: The L1-3 Mode command allows the user to select the radio's operating mode (analog wide, analog narrow, or P25 digital). Once the user has selected the command, they can press to step up, or to step down through the choices. The advantage of the 'entry key' step method is that the user does not have to move their finger to a different key to make the choice once the command has been selected.

The Command Level is indicated in the 4th character position on the lower row of the display indicating a subscript '2'. The Command/Operator Level 2 maps the keys to provide a new set of functions for the operator as shown below. Note: The system is time limited in command levels above level 1. The system will automatically return to level 1 if a command has not been selected in five (5) seconds! L2-1 Create/Edit All Channel Information (MN/GD restricted)This command allows the user to create a new memory position (for Main channel only) or to edit all the parameters of an existing memory position (Main or Guard channels). The editor steps through the channel parameters in sequence from left to right across the screen. The edit functions here match those used to edit an individual parameter; in this case however selecting the ENTER key accepts the data and proceeds to the next step, rather than returning. Only after the last step does selecting enter save the data and exit. The ESC key will abandon the entire edit session without changing an existing channel or creating a new one. accept the entry and return abandon the entry and exit L2-1.1 Entering a Memory Number (refer to L1-1 for details) When the Create/Edit All command is selected, the first step is to enter the number of the memory position that you wish to Create or Edit. Note that if the Radio is on a Guard channel then the editor starts at the “Edit Text” prompt (step 3 below) as the memory number and scan cannot be edited for Guard channels. The valid range is (001 to 230) Once a number has been entered, the system checks to see if the memory location has already been programmed, if so, then the existing data will be loaded, if the location has NOT been previously programmed then the default template data will be loaded. In each case the user can edit the channel parameters in the same way as shown in the following steps. L2-1.2 Enter a Scan List & Enabling/Disabling Scan (refer to L2-5 for details) The cursor will move to the third (3rd) position on the top line, the default scan list is shown in subscript. If there is a bar over top of the character, this indicates that scan is disabled for this memory, if there is no bar, scan has been enabled. The 'PROG' key (key 0) toggles the scan enabled/disabled state.
TECHNISONIC INDUSTRIES LIMITED www.til.ca TDFM-136A Operating Instructions Page 2-13 TiL 09RE405 L2-1.3 Enter a Text Description (refer to L2-6 for details) After SCAN, the cursor moves to the first position in the eight (8) character text description field, the user may now edit the existing test as desired. The editor allows you to select all upper and lower (A-Z, a-z) case alphabetic characters, the numbers from zero to nine (0-9), and a selection of extra characters including the space. L2-1.4 Enter an Operating Mode (refer to L1-3 for details) After TEXT, the cursor is positioned on the one (1) character Operating Mode field. This single character represents the operation of the radio, analog wide, analog narrow, or digital. L2-1.5 Enter a Frequency (refer to L1-7 for details) The frequency parameter is a seven (7) digit decimal parameter, though the first digit is always one so the user cannot edit that digit. The frequency parameter may be edited to any number between 136.0000 and 174.0000 in 2.5 kHz steps (e.g. 150.0025 is valid, 150.0046 is not). This is a duplex parameter, that is, the user has a chance to edit both the receive value followed by the transmit value. Once the receive value has been accepted, pressing 'ENTER' again will accept the same value for transmit. L2-1.6 Enter the Squelch Parameters (refer to L1-9 for details) When the Create/Edit All command is selected, the first step is to enter the number of the memory position below) as the memory number and scan cannot be edited for Guard channels. Once the user is finished and selects ‘ENTER’ then the newly edited channel parameters are selected and displayed for the appropriate channel. This may take a moment as the information is programmed into the appropriate RF module at this time as well. L2-2 Copy Guard to Main Copy current Channel Parameters from Guard to Main (e.g. + ). Be sure you wish to do this, for it cannot be copied back from Main to Guard. This command is disabled from the factory as a safety precaution (L4-3 Command Permissions).

This command level does not preserve the Normal Operating display characteristics, that is: the Main and Guard displays are replaced by suitable command prompt information. Accessing the Maintenance Commands Access to the Level 4 commands is restricted to bench use only, in order to achieve this, the command level requires that a shunt be placed on a specific set of jumper pins on the MCU board of the radio. To do so refer to Figures 2-32 and 2-33, and follow these steps: 1. Ensure that the power to the unit is OFF. 2. Remove the left hand side cover (10 Philips screws) 3. Locate the 6-pin jumper field (approximately half way between the front and rear of the radio). 4. Place a 0.1” shunt on the set of jumper pins closest to the front of the radio. The user can now select level 4 (maintenance mode). FIGURE 2-32 Screw positions to remove the Left-hand Side Panel FIGURE 2-33 Shunt Position to Enable Level 4 Access NOTE: Jumper access to this command level MUST BE DISABLED when the radio is used in flight, maintenance mode commands are NOT required for flight operation.

TECHNISONIC INDUSTRIES LIMITED www.til.ca TDFM-136A Operating Instructions Page 2-30 TiL 09RE405 The basic operation of the TDFM-136A radio is accomplished through the front panel user interface. The front panel layout is shown in figure 2-41 below. FIGURE 2-41 The TDFM-136A Front Panel Layout The front panel comprises the following: A) LED display, two line x 24 character F) Toggle switch (two position: G1/G2) B) Rotary volume control (with on/off switch) G) Toggle switch (two position: HI/LO) C) Rotary volume control H) Keypad, twelve button (numbers 0-9, # and *) D) Push button switch (momentary contact) I) Keyloader E) Toggle switch (two position: MN/GD) A The display provides two lines of text information—in the normal operating mode, the top line provides information about the Main channel, the bottom line information about the selected Guard channel. B & C The rotary potentiometers control the audio level for each of the Main and Guard channels respectively. The Main volume control also contains the radio power switch. D The single pushbutton provides the squelch defeat function and opens the squelch in analog modes, and sets the receive squelch to accept all in digital modes (though this will not open the squelch unless there is a valid P25 digital signal present). E, F The three toggle switches allow the user to select: & G Main and Guard channels, Guard 1 or Guard 2 channel, and High or Low RF power. Note that the channel select switches (MN/GD and G1/G2) will control which channel is active for any channel editing command (see Sections 2.1 through 2.5). H The 12 button keypad allows the user access to the system commands including commands for selecting channels, editing channel parameters, and for system configuration. I Keyloader (for future use). PTT keying is provided via the back connector, and is part of a correctly installed system.
TECHNISONIC INDUSTRIES LIMITED www.til.ca TDFM-136A Operating Instructions Page 2-31 TiL 09RE405 Channels and Memories The radio supports 2 channels: Main, and Guard. The currently selected channel (ie that channel that the radio will transmit on when PTT is asserted) is determined by the position of the MN/GD, and G1/G2 switches. The Main channel supports multiple memory positions, that is, the user can select Main channel parameters by switching to a different memory position. The radio supports up to 230 memories for the Main channel. The Guard channel supports only two memory positions: G1 and G2 these memories are only accessible via the front panel switches. Memory Parameters (L1-3,7,9, L2-1,5,6, L4-1) Each memory has a variety of parameters that may be edited by the user, some are restricted under certain operating conditions: Example: while scan is available for any Main channel memory, the user may not set scan parameters for either Guard channel or for 'shadow' channels on the Main channel. The user can manipulate the memory parameters by using the editing commands described in sections 2.2 (Level1) and 2.3 (Level2). User accessible parameters include: • memory number • scan list • text description • operating mode • frequency • squelch mode and squelch mode value In addition to editing the memory parameters, the user can create new memories or edit all the parameters of a memory, using the command L2-1. When started, this command displays the contents of the memory (if currently programmed), or displays the default memory parameters, if creating a new memory (for Main channel only). The memory parameter defaults can be edited using the command L4-1. Operating Modes (L1-3) The unit supports three operating modes: Analog wide, analog narrow, and P25 digital. In the analog wide mode, the radio is operating on 25 kHz channel spacing, on both analog narrow, and in P25 digital mode, the radio operates with 12.5 kHz channel spacing. The user can easily switch between modes on any memory for any channel (e.g. any Main memory, and both Guard1 and Guard2). Since the squelch modes are not common across analog and digital operating modes, if you change across these modes, the Squelch Mode will be affected. The user can select the operating mode using the L1-3 command.
TECHNISONIC INDUSTRIES LIMITED www.til.ca TDFM-136A Operating Instructions Page 2-32 TiL 09RE405 Squelch Modes (L1-9, L2-9, L3-9, L4-9) The radio supports a variety of squelch modes for both analog and digital operation, these are shown in table 2-8 below. TABLE 2-9 Receive and Transmit Squelch Modes Analog Rx Analog Tx Digital Rx Digital Tx Rx Noise Tx Noise Rg TalkGroup + NAC Tg TalkGroup + NAC Rt CTCSS Tones Tt CTCSS Tones Rn NAC Only Ti ID Call Rc DCS Code Tc DCS Code Rm Monitor T- Inhibit T- Inhibit Squelch modes are non-orthogonal, that is, they are not the same across differences in Operating Mode or for receive and transmit operation. While the user might never use certain squelch modes for certain channels, the associated parameters are always there. Example: the user may keep a certain channel in analog narrow mode only, with no selective squelch chosen, but that channel does have a CTCSS tone, a DCS code, a TalkGroup and a NAC assigned, it is just that these parameters are not used. Each squelch parameter exists for each channel, and each has a default value, these default values, like all user editable channel parameters, can be set using the Maintenance Level command (L4-3). In addition, Squelch use may be restricted according to: which Squelch Modes may be selected for any Operating Mode, which Squelch Modes may be edited (e.g. change value), and – in the case of Tones and Codes – which values are available to be selected. See command L4-9. Analog Mode 'x' The analog squelch mode 'x' is the default squelch mode, in the case of the TDFM-136A, the default receive mode is noise squelch. In the case of transmit, there is no special selective squelch signal added. Analog Mode 't' The analog squelch mode 't', indicates that both receive and transmit use CTCSS tone selective squelch. The tones may be the same or different for receive or transmit. Analog Mode 'c' The analog squelch mode 'c', indicates that both receive and transmit use DCS (digitally coded squelch) code selective squelch. The codes may be the same or different for receive or transmit. Analog Mode '-' The analog squelch mode '-', is valid for transmit only, and indicates that transmit is disabled for this memory. Digital Mode 'm' The digital squelch mode 'm', is valid for receive only, and indicates that any non-encrypted P25 compliant digital signal, regardless of NAC or TalkGroup setting, will be received. Digital Mode 'n' The digital squelch mode 'n', is valid for receive only, and indicates that any non-encrypted P25 compliant digital signal, having the correct NAC, will be received.
TECHNISONIC INDUSTRIES LIMITED www.til.ca TDFM-136A Operating Instructions Page 2-33 TiL 09RE405 Digital Mode 'g' The digital squelch mode 'g', is valid for receive and transmit only. For receive it indicates that any non-encrypted P25 compliant digital signal, having the correct NAC, and the correct TalkGroup will be received. For transmit it indicates that the specified NAC and TalkGroup codes will be transmitted. Digital Mode 'i' The digital squelch mode 'i', is valid for transmit only, and indicates that the transmitted signal will carry the ID of a specific radio. Only a radio with that ID programmed as its UNIT ID (see command L2-9), should be able to receive that signal. Digital Mode '-' The digital squelch mode '-', is valid for transmit only, and indicates that transmit is disabled for this memory. ID Call Operation The radio can be configured, in digital mode, to use ID call as a selective squelch method, in this mode the transmitting unit sets it's TalkGroup to zero (0), and transmits the intended Unit ID number (decimal 0 to 9,999,999), upon seeing the '0' talkgroup, the receiver ignores everything except the ID number. Of course the receiver will have to be on the correct frequency, and in digital mode. The TDFM-136A has two (2) distinct RF modules (Main and a dedicated Guard receiver). Unit ID's are not selected at the factory (all units ship with default IDs of 1 for Main and 2 for Guard), so each of these needs to have a Unit ID programmed. Scan Operation (L1-5, L2-5, L3-5) The radio supports a basic scan mode that operates on the Main channel only. The scan function allows users to monitor up to 16 channels at a time. All memories must be a member of one, and only one, scan list; each scan list can hold up to 16 memories. Each memory in a scan list can be enabled for scan or disabled (see command L2-5). To scan a particular list: the radio must have a memory, with its scan enabled, selected for the Main channel. Example: There are seven (7) memories assigned to scan list three (3), channels 5, 6, 13, 15, 23, 34, and 51 are all members of scan list 3. Channels 6 and 15 have scan disabled, the rest have scan enabled. If the user is on channel 6 or 15 and tries to start scan (command L1-5), there will be an error message: “Error: Non-Scanned Chan” and nothing will happen. If the user is on any other channel in scan list three, then the five scan-enabled channels in list three will be scanned. You can enable or disable scan for the displayed memory (for Main channel only) by using the command L2-5. You can affect the scan operational parameters by using command L3-5. This command allows you to affect the following four (4) parameters: • Revert Mode • Reply Timer • Monitor Timer • Delay Timer
TECHNISONIC INDUSTRIES LIMITED www.til.ca TDFM-136A Operating Instructions Page 2-34 TiL 09RE405 Revert Mode The Revert Mode refers to whether the radio will, when keyed, transmit on the currently selected memory channel, or on the last contacted memory channel. The radio will only respond on the last contacted channel for a time determined by the Delay Timer setting, once the Timer times out, the unit then always transmits on the selected channel. Default: last contacted Reply Timer The scan Reply time is the time that the radio will monitor a channel on which RF was received, after all activity on the channel has ended (Rx or Tx). If there is further receive or transmit activity on the channel, the timer will reset, and start again once the activity has ended. When the timer times-out the unit will resume scan. If set to zero (0), the unit will resume scan immediately upon the end of channel activity. Range: 0-20s, Default: 3 seconds Monitor Timer This is the time that the radio will monitor a channel on which RF was received, before resuming scanning. Once the timer expires, the unit will break and resume scan, if the value is set to zero (0) then the unit will monitor the signal as long as it is received. Range: 1-90s, Default: 10 seconds Delay Timer The Delay time is the time that the radio will remain monitoring a channel after receiving on that channel has ended. If the timer is set to zero, (0), then the unit will resume scanning immediately after receive activity has ended. This is the timer that affects the Revert Mode 'Contacted'. Range: 0-15s, Default: 5 seconds Mixed Mode Operation (L2-7) The radio supports a mode of operation that allows mixing of analog and digital operating modes. In effect, this mode allows one memory position to be set up as though it has up to 8 sets of parameters associated with it. This mode is also referred to as 'multi-mode' or 'shadow channel' operation. The user invokes this mode by creating a 'shadow' memory (using command L2-7) and assigning it to an existing memory (known as the 'primary'). Any 'primary' can have up to seven (7) 'shadows' for a total of eight (8) sets of operating parameters (1 primary + 7 shadows). Each 'shadow' takes up one memory position, just like a normal memory. The shadows have certain restrictions: • a shadow must have the same frequency as the primary • a shadow cannot have scan enabled • a shadow cannot transmit in digital ID call (i) mode You can mix analog and digital Operating Modes, you can configure different shadows to have different squelch parameters. Shadow operation is much like scan in last contacted mode, once a signal has been received, the user has a set amount of time to key the radio, the unit will transmit with the parameters of the shadow that decoded the signal: in other words you will respond to the person who called you.
TECHNISONIC INDUSTRIES LIMITED www.til.ca TDFM-136A Operating Instructions Page 2-35 TiL 09RE405 When mixing analog noise squelch with analog selective squelches, the noise squelch shadow will delay decode for a short time to allow the selective squelch channels time to decode, if none of the selective squelch channels decode a valid signal, then squelch is broken on the noise squelch channel.
