The unit offers 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 138-150 MHz portion of the band. If the TFM-530 transceiver is used in CANADA, VHF operation is restricted to the following sub bands: 138-144, 148-148.99, 149.005-150.005 and 150.05-174 MHz. 1.2DESCRIPTION The TFM-530, Transceiver is a frequency agile, fully synthesized airborne transceiver capable of operating in the 138 to 174 MHz and 30 to 50 MHz frequency range in 2.5 kHz increments with either 25 kHz or 12.5 kHz channel spacing. The Transceiver can operate without restriction on any split frequency pair in either band and also incorporates a two channel VHF synthesized guard receiver. r provides 200 operator accessible memory positions per band, each of which is capable of storing a transmit frequency, receive frequency, transmit CTCSS tone or DPL code, receive CTCSS tone or DPL code, an alphanumeric identifier for each channel and wideband (25 kHz) or narrowband (12.5 kHz) channel spacing assignment. Operating frequency and other related data are presented on a 96 character, four line LED matrix display.

These features include: 1.VHF and VLO bands that can be configured to be operated independently or as a single 2-2 2-3 2.2OPERATING INSTRUCTIONS (See Figure 2-1) 1.Switch power on by turning the main volume clockwise. Depending how the radio is configured, either the last programmed or last displayed frequencies will appear on the screen. The transceiver is now in normal operating mode. 2.Adjust the audio level by adjusting the VHF, VLO and GUARD volume knobs. 3.Pressing the squelch defeat button will open all receivers to confirm they work. 4.Read the display. The top line will indicate which VHF memory is se lected followed by a "+" if the memory position is included in a scan list, an alphanumeric message, and the frequency of the VHF receiver. A small "n" before the frequency indicates 12.5 kHz narrowband channel spacing is in effect on this memory position. In the receive mode, the frequency is followed by an "RT" if a RX CTCSS tone or RX DPL code is programmed, or an "RX" if no Receive tone/code is programmed. Similarly, in the transmit mode either a "TT" or "TX" is shown after the frequency. The second line shows the same information for the VLO band. The third line indicates information about the VHF guard receiver. 5.Only TX CTCSS tones or TX DPL codes may be programmed for the guard receiver. At the beginning of each line, an LED indicates open squelch. 2-4 2.3PROGRAMMING INSTRUCTIONS To program one of the 200 memory channels in one of the bands: 1.Select the desired band on the band select ( VHF/VLO/GD) switch. This is required before any of the programming modes or functions. 2.Press the key. The display will s how the func 3.Press the PROG key. The display will show the current receive frequency with a flashing curser on the first or second digit (The firs t digit is always a one 1.9; on the VHF band). 4.Type in the desired receive frequency. If you type in a frequency which is not a 2.5 kHz step, the nearest valid frequency will be automatically selected. 2-5 2.4PRIORITY SCANNING, SELECTIVE MEMORY CHANNEL SCANNING AND SCAN LISTS Instead of breaking up the 200 channels into blocks for scanning, th e TFM-530 has 5 scan lists per band. Any of the 200 channels can be assigned to any one or more of these 5 scan lists. This means the channels do not have to be repeated to be in more than one block and that you are not limited to the number of channels that you can scan at once. The priority memory channel is always memory position number 1. The priority memory channel is scanned every other step (ie. 121314151...) to ensure that no incoming messages are missed. The priority channel can be locked out, which will result in the normal scanning of the other memory positions. Selective memory scanning allows the user to select which of the 200 memory channels are to be scanned or locked out when the scan function is invoked. To use this feature, follow the PROGRAMMING INSTRUCTIONS found in paragraph 2.3. Once the screen displays SCAN LOCKOUT 1,2,3,4,5 or M.DN keys to toggle to the desired condition. The button acts as a clear while pressing one or more of the above numbers adds the memory to the corresponding scan list or lists. Press ENTER when you are happy with your selection. In normal operating mode the displa y will later show a "+" beside the memory channel number if it has been included in any of the 5 scan lists. NOTE: Scanning can only be performed on one band (either VHF or VLO) at a time. When the transceiver is in the single mode (combined VHF and VLO audio) and the scan feature has been invoked on one band, it will be interrupted when transmitting on the other band. In the Dual mode, you are able to transmit on the second band without effecting the scan function on the first. 2.5SCANNING FUNCTION (5 second talkback delay) Select the band you wish to scan with the band switch. (you can not scan the guard) To start scanning of the memory channels, press then SCAN and then the number (1,2,3,4,5) of the desired scan list. 2-6 2.6DIRECT FREQUENCY ENTRY MODE This mode is designed to facilitate quick fr equency selection duri operational conditions requiring direct operating frequency selection. This operating mode is disabled along with the programming mode wh 2-7 2.10LED DISPLAY VARIABLE DIMMING MODE 1.With the transceiver in normal operating mode press the or DN keys to increase or decrease the intensity of the LED display. 2.Once maximum intensity of the display is achieved, the key no longer functions. Conversely once minimum intensity is reached, the key ceases to function. 2.1190 SECOND TRANSMITTER TIME OUT FEATURE A selectable 90 second transmitter time out feature is provided to prevent accidental continuous transmission in the event of a faulty PTT switch. With this feature enabled the transceiver will stop transmitti ng after the PTT is engaged c ontinuously for 90 seconds. The 4.Use the M.UP M.DN keys to select the tone number you require.

Before connecting, verify the required panel lighting voltage (28 VDC or 5VAC) on the transceiver configuration control label. 3.7.5Audio Outputs (600 ohms and 4 0hms) There are two audio outputs available (1 & 2). 600 ohm audio output 1 has audio from both bands and the guard in single operator mode. When in dual operator mode, 600 ohm output 1 has audio from the VHF band and gua rd only while the VLO audio will be on the 600 ohm output 2. 3.7.6Audio Output Ground Pin 10 is the ground for both the 4 ohm audio output signals. 3.7.7Mic Signal Input The microphone input signal is to be provided on pin 6, utilizing shielded wire with the shield grounded to pin 10. Microphone signal 2 is on pin 6 of the 9-pin D connector. 3.7.8Memory Up/Memory Down Remote scrolling through the 200 memory positi ons can be achieved to pins 4 (up) and 5 (down) through a momentary contact cyclic switch. The memories will scroll only on the band selected. 3.7.9Data Input Data communications equipment requiring direct access to the VHF modulator and discriminator and can be connected via pins 2 and 11. Data cannot be transmitted in CANADA unless equipment is approved for use with the TFM-530 by the communications regulatory authority. 3-6 3.8INTERNAL PROGRAMMING AND GUARD ENABLE/DISABLE JUMPER The programming and direct frequency entry modes can be disabled by removing the internal enable/disable jumper strap from pins 1 and 2 of J10. Removal of this jumper will prevent operation on any frequencies other than those programmed in the 400 memory positions and two guard receiver memory positions. Removal of the guard receiver programming enable /disable jump er strap from pins 1 and 2 of J11 will totally disable the operator’s ability to re-program the 2 guard receiver channels. The transceiver is always shipped with the two jumpers in the entry enable positions. To place either of the jumper 1.Remove the left side of the radio. 3-7 3.9TRANSMITTER POWER ADJUSTMENTS The transmitter power is adjusted to a maximum of 10 watts in high power mode and 1 watt in low power mode over the transceiver operating bandwith at the factory.

As the TFM-530 installation may include the ATC-550 antenna tuner controller, this test, as required, will also identify any interference caused by the ATC-550. TEST CONDITIONS ATC-550) s tested. The antenna VSWR should be checked. A forward/reverse power check with a in-line A-2 RESULTS If the installed system passes all of the applicable EMI tests, then no further action is required. If interference is observed then the interference must be assessed against the appropriate standards of airworthiness for the system in question.
