SECTION 2 – OPERATING INSTRUCTIONS
2.1 OPERATING FEATURES
The equipment has several important operating features which provide maximum flexibility, performance and versatility. These features include:
1.
2.
120 memory positions which can each be programmed with a transmit and receive frequency with 25 or 12.5 kHz channel spacing, Tx/Rx CTCSS tones or DPL codes and a 9-character alphanumeric title.
Two guard channels which can each be programmed with a Rx frequency with 25,
20 or 12.5 kHz channel spacing, CTCSS Tx tone or DPL code and a 9-character alphanumeric title.
3.
4.
5.
6.
7.
8.
Scanning of preprogrammed memories with selective memory scanning, in 5 scan lists.
Priority scan of memory channel 1, if desired.
Direct frequency entry mode.
Receive frequency simplex function.
Switchable RF output power between 1 watt and 8-10 watts.
Lockout of keyboard to prevent inadvertent entries.
9. Variable frequency mode to manually scan up and down in 2.5 kHz steps.
10. LED display variable dimming mode.
11. Selectable 90 second Tx time out feature.
12. Quick download of any of the 120 memory positions to the guard memories.
13. PC Memory Upload or download capability.
14. Guard jumper (J15) to enable/disable Guard programming.
15. Compatibility with industry standard Antenna Tuner Unit.
16. Configuration Menu to enable/disable various functions as follows:
1. Configuration Menu - Pressing ENTER, RCL and FUNC together with all 3 front panel switches in the “up” position while turning the radio on will put it into configuration mode. The programming features that can be configured by this menu include:
a. DPL – Can be turned on or off with the MUP and MDN (4 and 7) keys.
This only removes the DPL entry step from the programming sequence and does not stop memories that already have DPL codes from working.
This also applies to the rest of the on/off configurable items. b. Scan – Can be disabled. Selecting FUNC and SCAN will do nothing if
Scan is off. The scan list indicator (+) will still display if it was previously programmed. c. Rx CTCSS – Can be turned on or off from the programming sequence.
This affects only the CTCSS tones for receive. d. FUNC 7 - Can be turned on or off. When off, the main memory channel can not be dumped into one of the guard channels using function 7. e. LAST MEM – If set to on, the last memory channel on the display will be what comes up when the radio is turned on. If set to off, the last memory that changes were made to will be what comes up when the unit is switched on.
2. Guard Jumper - Programming of the guard channels can be totally disabled by removing J15. This way, the radio has to be disassembled in order to reprogram either of the guard frequencies.

2.2 OPERATING INSTRUCTIONS (See Figure 2-1)
1.
2.
Switch power on by turning the main volume clockwise. Depending how the radio is configured, either the last programmed or last displayed frequency will appear on the screen. The transceiver is now in normal operating mode.
Adjust the audio level by adjusting the main and guard volume knobs.
3.
4.
5.
Pressing the squelch-defeat button will open both receivers to confirm they work.
Read the display. The top line will indicate which memory is selected followed by a
"+" if the memory position is included in a scan list, an alphanumeric message, and the frequency of the main 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 bottom line indicates similar information about the guard receiver.
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.
6.
7.
Set the MN/GD switch to main or guard transmit frequency.
Set the G1/G2 switch to the desired guard channel.
8.
9.
Set the HI/LO switch to the desired RF output power.
Select the desired memory by using the M.UP and M.DN buttons, or the RCL button and a three digit number followed by ENTER.
10. To transmit DTMF tones, use the keyboard keys while holding the PTT button on the microphone. The keyboard returns to its normal function when the PTT is released.
The display always shows the status of both receivers and the transmitter. The light at the left of the top and bottom line indicates which receiver is receiving. The display also indicates the memory channel in use and the guard channel in use. A "TX" (no TX tone/codes programmed) or "TT"(either TX tone or code programmed) on the right side of the display indicates whether the guard or main channel is active when transmitting. The transmit frequency is also shown. In the receive mode the display shows “RX” beside the receive frequency if no RX tone or DPL code is programmed and “RT” if a CTCSS tone or
DPL code is programmed.
When the transceiver is in either of the operating frequency or CTCSS tone/DPL code programming modes and you must respond to a call, click the microphone PTT once (the radio will not transmit during this click). This will cause the transceiver to revert back to the normal operating mode and communications with the caller can proceed in the usual fashion.
The TFM-30 was designed for compatibility with an industry standard Antenna Tuner Unit through the 9-pin connector on the rear panel of the radio. The ATU is enabled during transmit.

2.3 PROGRAMMING INSTRUCTIONS
To program one of the 120 memory channels in the TFM-30:
1. Press the FUNC key. The display will show the function prompt.
2. Press the PROG key. The display will show the current receive frequency with a flashing cursor on the first digit (The first digit is always a <3>, <4> or <5>).
3.
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.
The cursor will return to the second digit. You can now retype the frequency if you made an error or press ENTER to continue.
5.
6.
The transmit frequency will be displayed with the cursor on the second digit. Follow the same method as in step 3 and 4.
The channel spacing increment of either 25 or 12.5 KHz is now displayed. Use the
M.UP and M.DN keys to select the desired channel spacing for the memory position, then press ENTER.
7.
8.
The alphanumeric title is now displayed. Use the M.UP and M.DN keys to scroll through the alphabet, numbers and symbols. When the desired character is displayed, press ENTER to advance to the next character. Press “1" to backspace.
Keep repeating step seven until the last space is set. The display will show SCAN or
LOCKOUT to enable this memory position as part of a scan list or lock it out of the scan list. Use the 1,2,3,4,5 and M.DN keys to toggle between these functions (for details, see paragraph 2.5). Once the desired condition has been selected, press
ENTER. The TFM-30’s display will show a "+" beside the memory channel number if scan is enabled.
9. The display will now show the current memory number. Type in the 3-digit number of the memory you want to save to (if different from displayed one) and press
ENTER.
10. You now have the option to program the guard frequencies by pressing FUNC or press ENTER to return to normal operating mode.
11. If you pressed FUNC to program the guards, guard "1" transmit frequency will be displayed with the flashing cursor on the second digit. Enter the frequencies for guard "1" receive/transmit and guard "2" receive/transmit as in step 3 and 4.
12. The alphanumeric labels for guard "1" and guard"2" are entered the same as in step
7 and 8. When the last character is entered, the radio returns to normal operating mode. If the guard is be programmed for 12.5 kHz narrowband operation, use the
QUICK GUARD PROGRAMMING FEATURE described in paragraph 2.12. A memory position must be programmed to the 12.5 kHz mode then the contents can be quickly downloaded to GD1 or GD2 memory positions.
Programming of memory is disabled when the internal entry disable jumper is set.
Alternatively any transceiver can be programmed by an IBM PC or compatible computer.
See section 2.14 PC Memory Programming Up/Download Capability.

2.4 PRIORITY SCANNING, SELECTIVE MEMORY CHANNEL SCANNING AND SCAN LISTS
Instead of breaking up the 120 channels into blocks for scanning, the TFM-30 software has
5 scan lists. Any of the 120 channels can be assigned to any one of more of these 5 scan lists. This means the channels do not have to be repeated for them to be in more than one block and that you are not limited to the number of channels that you can scan at once, since all 120 channels can be put into any scan list.
The priority memory channel is always memory position number 1. The priority memory channel is scanned every other step (e.g. 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 120 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 or LOCKOUT, use the 1,2,3,4 or 5 key to add the channel to the corresponding scan list or lists. The M.DN key acts as a clear button removing the channel from all scan lists and displaying LOCKOUT. Press ENTER when you are happy with your selections. In normal operating mode the display will later show a "+" beside the memory channel number if it has been included in any of the 5 scan lists.
2.5 SCANNING FUNCTION (5 second talkback delay)
1. To start scanning of the memory channels, press FUNC then SCAN and then the number (1,2,3,4,5) of the desired scan list.
The radio will scan through all the preset memory positions in the selected scan list (see above paragraph for priority and selective scan features) and will lock on to the first active channel in the scan sequence. It will remain on the channel until it becomes inactive.
Scanning will resume again after five seconds of inactivity. To exit the scan mode, press the SCAN key. This will cause the radio to revert back to the normal operating mode.
If while scanning, you hear a call for you:
•
•
Respond to the call within 5 seconds. When scanning is interrupted by an incoming signal, the channel will remain open for five seconds before resuming scanning.
During communications the five second timer is reset from the last Rx or Tx signal encountered.
The radio resumes scanning once the Rx or Tx activity has ceased for more than five seconds. The SCAN key must be pressed to exit the scan mode.
2.6 DIRECT FREQUENCY ENTRY MODE
This mode is designed to facilitate quick frequency selection during emergency and other operational conditions requiring direct operating frequency selection. This operating mode is disabled along with the programming mode when the internal disable jumper is set.
When the transceiver is in the normal operating mode, press FUNC and the desired operating frequency (e.g. 39.275).
Please note in the above operation, after FUNC and the first digit are entered, the LED display will show memory channel "000" and then the remaining digits in the desired frequency are shown as they are entered. No alphanumeric message can be entered in this mode. Operation on the new frequency occurs in both transmit and receive (simplex only) modes. If RX or TX CTCSS tones/DPL codes are required, they must be programmed in.

2.7 RECEIVE FREQUENCY SIMPLEX FUNCTION
The receive frequency simplex function allows you to quickly change the transmit frequency, when operating on a split pair (repeater/semi-duplex mode), to the receive frequency to allow direct communications. (For example, if you are transmitting on 42.000
MHz and receiving 42.555 MHz, press FUNC, then UP to transmit on 42.555 MHz. To return to the split pair condition, you must recall the memory channel again. This is quickly done by pressing M.UP for one step up, then back down one step with the M.DN key.)
2.8 KEYBOARD LOCKOUT FUNCTION
The keyboard can be locked out so that accidental pressing of keys does not change frequency, etc., unknowingly to the operator. To lock the keyboard, press FUNC then LOCK.
This will disable all keyboard functions (except keyboard unlock) in the receive mode. The
DTMF function during transmit will not be affected. To unlock the keyboard, press and hold the LOCK key for two seconds until the display indicates "UNLOCK".
2.9 VARIABLE FREQUENCY MODE FUNCTION
To enter variable frequency mode, press RCL, 0,0,0, then ENTER. The memory channel that you were just in will still be valid but now you can manually adjust the frequency with the
M.UP, M.DN, UP and DN keys. The UP and DN keys will make the frequency count up or down in steps of 2.5 kHz. The M.UP and M.DN keys will make the frequency count up or down in steps of 1 MHz. You can not change the label. The frequency in this mode cannot be stored in memory. To exit this mode, recall one of the 120 memory channels (e.g. RCL,
0,0,1). Variable frequency mode is disabled when the internal entry disable jumper is set.
2.10 LED DISPLAY VARIABLE DIMMING MODE
1.

2.14 PC MEMORY PROGRAMMING UP/DOWNLOAD CAPABILITY
The Technisonic Data Programmer (Multi-TDP) Windows based software is supplied on a CD with the TFM-30 transceiver or is available for download from our web site www.til.ca. This software will allow anyone with a standard personal computer (PC) and the PIB-100 programming box to send or retrieve data from a connected TFM-30 transceiver for editing, sorting and sharing with other Technisonic transceivers.
The Multi-TDP programmers are 32-bit Windows applications that will work under Windows
95/98, Windows NT 4.0 and Windows 2000. Documentation for each of the respective
Programmers is available from the pull down "Help" menu at the top of the programmer display. To use the Windows based program with the TFM-30, the PIB-100 programming interface box P/N 001108-1 includes all required cables and must be purchased from
Technisonic or other re-sellers.
The CD supplied with the transceiver also contains a DOS based download program that can be used with the TFM-30 and no interface box. However, changes in operating systems and
PC hardware that have occurred since the release of our DOS compatible software prevent it from working with most modern computers. Computers with 486 processors or some early Pentium type processors of 200 MHz or less running MS-DOS seem to work the best.
Please check the “Programmer downloads” link on our website www.til.ca for further information regarding PC programming information for users of single band transceivers like the TFM-30.
The user instructions for the Windows based Multi-TDP software and then the DOS-based software follow below.

APPENDIX A– POST INSTALLATION EMI TEST INSTRUCTIONS
PURPOSE
The purpose of this test is to identify any interference that the TFM-30 may cause with existing aircraft systems.
TEST CONDITIONS
The TFM-30 should be installed and function tested. The antenna VSWR should be checked. A forward/reverse power check with a in-line wattmeter should show no more than 10% reflected power.
METHODOLOGY
Most of the EMI tests can be accomplished on the ground. In some cases, flight testing is required or easier. If the aircraft is approved for IFR operations, then it is mandatory that interference between the TFM-30 and the approach aids be checked in flight.
The GPS should be operational and navigating with at least the minimum compliment of satellites. The VHF comm should be set to the frequencies indicated with the squelch open.
VOR/ILS/GS receivers should be set to the frequencies indicated and selected for display. If possible, set up a VOR/ILS ramp test set on the frequencies indicated and adjust the output until the flags are out of view. The transponder and encoder should be monitored with ramp test equipment. If possible set the ADF to a nearby navigation station.
Modulate the TFM-30 transmitter on the indicated frequencies for at least 20 seconds.
Observe the GPS for any degradation in satellite status or availability or flags. Listen for any noise or detected audio signals on the VHF comm(s). Listen for any noise or detected audio signals on the VOR/LOC receiver audio. Look for any moment of flags or needles on the
VOR/LOC/GS navigation display(s).
List the power plant, fuel and other electric instruments in the chart provided and note any anomalies that occur while transmitting. Assess the results.
If the aircraft is equipped with an autopilot or a stability augmentation system, then test fly the aircraft and verify that the operation TFM-30 does not have adverse effects on these systems. After checking for gross effects at a safe altitude, fly an approach with each of the different navigation systems coupled to the autopilot (ILS, GPS, etc.) and look for any anomalies.
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. For example it is permissible for a VFR certified GPS to lose navigation capability while the TFM-30 is transmitting, providing that it recovers properly and promptly, but it is not permissible for an
IFR Approach certified GPS to be affected in the same way.
A complete discussion of all the standards of airworthiness to be applied in assessing EMI effects is beyond the scope of this document.
