Compatibility with industry standard Antenna Tuner Unit.
Configuration Menu to en/disable various functions as follows:
Configuration Menu - Pressing ENTER, RCL and FUNC together with all it switches
up while turning the radio on will put it into configuration mode.
The programming features affected are:
a) DPL ~ Can be turned on or off with th 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.
bl Scan - Can be disabled. Selecting FUNC and SCAN will
do nothing if Scan is off. The scan list indicator (+l
will still display if 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.
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
revprogram either of the guard frequencies. This may be required on
US Forest Service contracts.

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 new in normal operating mode.
Adjust the audio level by adjusting the main and guard volume knobs.
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 efleot on this memory position. In the receive mode,
the frequency is followed by an "RT" if a RX CTCSS tone or FIX DPL code is
programmed, or an "RX" if no Receive tone/code is programmed. Similarily, in the
transmit made either a I'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.
Set the MN160 ‘swltch to main or guard transmit frequency.
Set the GilGZ switch to the desired guard channel.
Set the Hl/LO switch to the desired HF 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.
To transmit DTMF tones, use the keyboard keys while holding the FTT 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" lno TX tone/codes programmed)
or "T'I'"leither 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 displav 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 P'I'l' 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 compatibilty 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.

Press the FUNC key. The display will show the function prompt.
Press the FROG key. The display will show the current receive frequency with a
flashing cursor on the second digit lThe first digit is always a one <1 >l.
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.
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, 20 or 12.5 KHz is now displayed. Use the
MU? and M.DN keys to select the desired channel spacing for the memory position,
then press ENTER.
The alpha-numeric 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 six 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.
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.
You now have the option to program the guard frequencies by pressing FUNC or press
ENTER to return to normal operating mode.
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.
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 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 (3132 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 Download Capability.

2.6
PRIORITY SCANNING. SELECTWE 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 lie. 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 1,2,3,4,5 or M.DN keys to toggle to the desired condition and press ENTER.
Entering the any or all of the numbers 1,2,3,4 or 5 will include that memory channel in any of
the five scan lists. 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.
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.
Therefore if while scanning, you hear a call for you:
1. 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.
2. During communications the five second timer is reset from the last Rx or Tx
signal experienced.
The radio resumes scanning once the Fix or Tx activity has ceased for more than five seconds.
The SCAN key must be pressed to exit the scan mode.
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.
1. When the transceiver is in the normal operating mode, press FUNC and the desired
operating frequency ie/ 39.275.
Please note in the above operation. after FUNC and “1" 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.

RECENE 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 model, to the receive frequency to allow
direct communications. ie/ 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.
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".
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 can not be stored
in memory. To exit this mode, recall one of the 120 memory channels iie. RCL, 0,0,1). Variable
frequency mode is disabled when the internal entry disable jumper is set.
LED DISPLAY VARIABLE DIMMING MODE
1. With the transceiver in normal operating mode press the UP or DN keys to increase or
decrease the intensity of the LED display.
2. Once maximum intensity of the display is acheived, the UP key no longer functions.
Conversely once minimum intensity is reached, the DN key ceases to function.
90 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 wrll stop transmitting after the PTT is engaged continuously for 90 seconds. The
timer is reset by releasing then re~engaging the MT switch.
Press the FUNC then the M.UP key. Use the M.UP and M.DN keys to select 90 SEC, which
enables the feature, or NONE which disables it.
QUICK GUARD PROGRAMMING FEATURE
A quick download of any of the 120 memory positions to either of the guard memory positions
can be accomplished. Select the memory position whose contents you desire to download to
a guard memory. Select either 601 or GDZ memory channel as desired. Press FUNC then 7.
The guard memory channel will now contain all the same information as the selected memory
position. This feature is disabled when guard jumper lJ15, pins 1&2) on the MCU board is
removed.

2.13
PROGRAMMING CTCSS TONES/DPL CODES
CTCSS tones (PL tones) or Digital DPL codes can be assigned to each memory channel. The
guard receiver squelch will operate only on carrier detection, but guard 1 and 2 transmit tones
or codes can be programmed. To program a tone/code to a memory channel:
1.
Use the M.UP and MD" keys to select the memory channel that you went to assign
a CTCSS tone or DPL code.
2. Press the FUNC key then the TONE key. The display will show "RX TONEz" and the
current tone number, as well as the Long fregjggnpy in Hz
3. Use the M.UP and MD!“ keys to select the tone number you require. The following

PC MEMORY PROGRAMMING UP/DOWNLOAD CAPABILITY
The TFM-30 transceiver can be programmed by an MS-DOS based personal computer. This is
an alternative to programming data manually by the keypad. The programmed information can
also be removed from the TFM730 and stored in a PC. A 3.5" disk containing the required PC
up/downloed software is provided with each TFM-30 transceiver.
Requirements:
1. PC compatible computer with any monitor, 3.5" floppy drive and a printer port
(LPT1).
2. Bench power supply of 12 to 30 volts DC. The TFM—SO requires 28 volts to
operate fully (transmit) but can be programmed at voltages as low as 12 volts.
34 PC download cable, P/N 943165-2 which can be supplied or made from the wiring
diagram at the back of this section. (PIN 943165-1 will only provide download
capability, upload will not be possible].

PO MEMORY/PROGRAMMING DOWNLOAD CAPABILITY - continued
Installation:
1. Insert the floppy disk into drive A and type: AleSTALL 
2. All the files will be copied to your hard drive into a directory called \TIL.
Connections:
1. With the PC turned off, plug the 25 pin male 'D‘ connector into its printer port.
2. Plug the 15 pin 'D' connector into the back of the TFM-30 transceiver.
3. Connect the power wires to the power supply.
Running the program:
1. Turn on the power supply and the TFM-SO unit first and then turn on the PC.
2. Change to the \TIL directory and type: PCDLSO and . The main menu will be
displayed.
Listing memory channels:
The first channel listed (in blue on colour monitors) is the memory channel that will appear on
the display of the TFM-SO unit when it is turned on. The next two channels listed are
guard 1 and guard 2. (in red on colour monitors) Only TX CTCSS tones or TX DPL codes are
listed for the guards since the TFM-30 unit has a CTCSS tone/DPL code decoder for the main
receiver only. The rest of the memory channels displayed (in yellow) are the 120 memories
listed in sequence. Either LOCK or SCAN LIST numbers “1.2.3.4,5" are displayed for each
memory channel which indicates whether that memory channel will be included in any of the
5 scan lists or locked out. After the scan information, an “N' or blank space will follow to
indicate nerrowband or wideband mode respectively. After reviewing the multi-page list, you
have the option to return to the first page, for further review or to return to the main menu.
Printing Memory Channels:
To print out a listing of the memory channel database, the pc download cable must be removed
from the printer port (LPT1) and a printer plugged in. Select ‘P’ from the main menu. You will
be prompted for a title that will appear on the listing. This could be for example the serial
number of the radio. Press  and the printing will start. The main menu will appear
when printing is complete.
Edit menu:
You can select which memory channel to program, main or guard. When entering memory
channel information, if you just press return, the previous information will be retained. For
example, you only want to change the receive frequency. Type in the new receive frequency
and press return for all of the other prompts. You also will not be able to type in frequencies
or information that does not make sense. If the information entered is not what was prompted
for, you will be re-prompted for the correct information. For example, if you type in 999.9999
for the transmit frequency you will be prompted again because the frequency range of the TFM-
Edit menu: (continued)
30 product is 30 to 50 MHz. Keep in mind that the label for the memory channel can only have
characters that exist on the ”(FM-30 unit. These include only capital letters, numbers 0 to 9 and
a few other characters. Any other character will show up as a blank on the unit‘s display.
You will then be prompted to enter a receive CTCSS tone, 5 transmit CTCSS tone, a receive
DPL code and a transmit DPL code. Although both CTCSS tones and DFL codes can be
programmed simultaneously, this should not be done. Care should also be taken to program
the correct DPL ccde since non-unique (inverted) code numbers will be accepted,
Downloading to the Transceiver:
Select 'D' from the main menu. Follow on screen instructions. The memory channels will be
downloaded sequentially to the TFM»30 unit. You will be able to see them on the radio's
display as they go by. The download process will take less than one minute. (The data transfer
is fast but the nonvolatile memory in the radio needs time to program.) The PC will return to
the main menu when the process is complete. The radio will also return to the normal operating
mode when done.
Selecting ‘0’ from the main menu will enable you to download a single memory to the radio.
You will be prompted for the originating memory number (in the database), then the destination
memory number (in the radio). This makes it possible to place data into radios that have
different channel listings and not load a memory on top of one that was still desired. Follow
on screen instructrons to complete download.
Uploading From the TFM-30:
Uploading from the radio is started by selecting ‘U' in the main menu. Follow on screen
instructions. The upload should take about 10 seconds depending on the speed of the PC.
The previous data base will be replaced by the contents of the radio. If the previous database
is still needed, the tile ‘DATA30' should be copied to another file name in DOS before the
upload is attempted.
Files:
The file containing the memory channel list is named 'DATA30' in the tTIL directory. The
program will not run it it can not find the ‘DATA30‘ file. To have multiple databases, you can
copy the data file to a new name and edit the 'DATASO’ file again. To retrieve a database,
copy it back to 'DATA30'.
