STC APPROVAL NOTE
Presently, no TSO standard exists for airborne FM transceivers. To make it easier for installation
agencies to provide their customers with an approved installation supported by an effective Airworthiness
Approval, Technisonic has secured Supplemental Type Certificate (STC) Approvals (both US and
Canadian) on its Airborne FM products for many helicopters currently being delivered in the US and
Canada as well as a number of single engine fixed wing aircraft. The above referenced DO-160C test
data is also on file and available from Technisonic to support approval requirements in airframes for
which Technisonic does not possess an STC.
Approved aircraft types are listed in the attachments to the formal STC documents. These STCs are the
exclusive property of Technisonic and require the written authority of Technisonic for their use. To assist
Factory Authorized Technisonic Dealers in the certification process, we have placed copies of our
Canadian and US STCs on our web site along with a letter of authorization for their use. These
documents may be downloaded and used as support for the technical submission to FAA or Transport
Canada. Only authorized factory dealers/installers are permitted to download and make use of these
documents on behalf of their customers (end users) in support of regulatory agency approval. Please
refer to the Technisonic web site www.til.ca for the latest issue of available STCs and letter of

SECTION 1 - GENERAL
DESCRIPTION
1.1 INTRODUCTION
This publication provides operating and installation information on the TDFM-7300-3 airborne
transceiver. The exact configuration depends on which and how many RF modules are installed.
1.2 DESCRIPTION
The TDFM-7300-3 transceiver is an airborne multi-band radio capable of operation in
conventional analog and P25 digital FM systems, SmartNet/SMART ZONE trunking systems and
P25 9600 trunking systems. Type II RF modules are available in VHF, UHF LO, UHF HI and
700/800 MHz bands.
These optional additional features include P25 9600 Baud trunking that may be combined with
AES and/or DES-OFB encryption with OTAR in any of the available modules.
Bands 1 through 4 on the TDFM-7300-3 are not normally frequency agile. In order to have the
ability to change the frequencies at the front panel, the FPP (front panel programming) option
must be ordered. FPP is only available on the VHF and UHF modules. The FPP option precludes
trunking and limits available channels to 240 (15 zones/16 channels) on that module instead of
1000 channels. Please note that all 240 memories must be filled if FPP is ordered.
The TDFM-7300-3 has provisions for four of the above RF modules as well as one analog only
module. This additional module is fully frequency programmable from the front panel and covers
the aviation band 117.975 to 138 MHz AM.

SECTION 2 – OPERATING
INSTRUCTIONS
2.1 GENERAL
A 6-line display and a keypad and a rotary knob provide the operator control of up to 5 RF
modules installed in the unit. The display is showing the activity of all 5 modules (bands) as well
as the menu of the active band, selected by pressing the BAND key. The knob has multiple
functions including volume, and channel. The microphone, key line and headphone audio can be
wired separately for each of the 5 bands therefore switching from band to band is performed at an
audio panel such as the Technisonic A71X series. This allows for separate and simultaneous
operation on each of the bands just like having 5 separate radios. The transceiver can also be
connected so that all bands are available on the combined output. In this configuration, the BAND
key on the transceiver must perform switching between bands. It is possible to connect the
transceiver such that both methods are used.
2.2 FRONT PANEL

TECHNISONIC INDUSTRIES LIMITED
2.3 POWER SWITCH
To switch the transceiver on, press and hold the knob until the radio powers up. The display will
show TECHNISONIC and the software version installed followed by the model number along with
which RF modules are installed. The display will then show the normal display. To switch off the
transceiver at any time, press and hold the knob for 2 seconds until the display shows OFF then
release. If it is desired that the radio powers up with the radio master in the aircraft, a power
jumper may be installed (see installation instructions) such that the radio is always on. The
battery master must be used to turn the radio off with this jumper installed.
2.4 KNOBS
The knob is a rotary encoder, which turns endlessly, meaning its actual position is not important.
The knob also has a push button incorporated in it so you can press the knob as well as turn it.
The knob will start out as a volume control. Pressing the knob again will change its function to act
as the channel selector. Pressing the knob again causes the keypad function to change from
function keys to number keys. The knob in this mode acts as a volume control. Another knob
press will bring you to the recall mode. In the recall mode, typing in the channel number will bring
you quickly to that channel without scrolling through channels in between. Pressing the knob
again brings it back to the volume control mode. The current function of the knob is shown at the
bottom right of the display.
2.5 SOFT KEYS AND HOME
The transceiver has three soft keys, which assume the function shown on the menu above them
on the display. The functions displayed depend on how the module was programmed with the
customer programming software (CPS)™. These menu items can be different on a channel by
channel basis. Typical menu items may include:
ZONE - Pressing this function will prompt you for a new zone number which can be entered
directly (if the keypad is in numlock mode) or scrolled using the UP(5) and DN(8)
keys.
MUTE - Selecting this function will prompt you for an on or off entry using the soft keys to
mute the tones. Tones refer to the beeps heard when pressing buttons.
PWR - Selecting PWR will allow the power output of the radio to be set to high or low.
PROG - Selecting PROG brings you to user programmable features of the radio such as
telephone numbers or scan lists. The ability for the user to program phone numbers,
scan lists, etc can be enabled or disabled by the CPS™.
VIEW - The view function is used to view lists. Lists can include scan lists, phone numbers,
call lists and or paging.
- Front Panel Programming mode allows you to program at the front panel without the
FPP
customer programming software. This option is available on VHF and UHF type II
modules and is always present on band 5 (analog VHF low band module).
At any time while in one of these functions, you can escape back to the normal mode by pressing
the HOME key. When programming the modules with the CPS™, it is suggested not to double up
functions. For example, programming a soft key to CHAN would be redundant since there is
already a channel function using the knobs. Using the CHAN soft key would also not update the
channel number on the display, causing some confusion.

You can select any two bands to cross band repeat. The repeat
function is semi-duplex. This means the TDFM-7300 will
retransmit from one band to another in both directions but not
simultaneously.
This is the same menu that can be invoked during boot up.

2.16 CUSTOMER PROGRAMMING SOFTWARE (CPS™)
Programming the Bands 1 – 4 of the TDFM-7300-3 is usually done with the use of third party
programming software. Customer programming software or “CPS” must be supplied by Motorola.
To make any changes to the programming in the Type II radio, Motorola CPS™ software must be
used. There is no provision in the TYPE II modules to allow the user to change frequencies,
zones, PL tones etc. unless the Front Panel Programming (FPP) option has been purchased in
each band.
A Programming cable is required to connect the computer to the TDFM-7300-3. Bands 1 - 4 in
the TDFM-7300-3 are considered a XTS-5000 model III portable by the CPS™ software. To
program a band in the transceiver, it must be selected by pressing the BAND key before running
the CPS™. Follow the instructions supplied with the CPS™.
The CPS Programming software must be purchased from Motorola On Line (MOL).

Programming Using Computers With No Serial Ports
Newer PCs and laptops are now being made without serial ports. For those computers to
program the TDFM-7300-3, a USB to serial adaptor will be required. USB to serial adaptors can
be found at most computer stores.
To use the adaptor, plug in the USB cable and install the USB to serial driver on the target PC.
The driver is usually supplied with the adaptor on a CD. This will create a “virtual serial port.
Once the adaptor is installed on the PC, find out what com port has been created by the adaptor.
Usually it will be Com 3, Com 4 or Com 5.
Refer to the PC’s operating system “Device Manager”.
The serial port will have to be set in the CPS software before programming can take place.
Start the CPS software, then click on VIEW then OPTIONS. Click on the MAIN tab and go to the
bottom pull down menu called “Port Selection”.

2.19 FRONT PANEL PROGRAMMING (FPP) MODE (Bands 1 – 4)
One of the bands may have the capability to program channel information such as frequencies,
PL tones, modulation types, etc from the front panel. ‘FPP’ will show up as one of the soft menu
items at the bottom of the screen if this option has been ordered. When the FPP soft key is
pressed, you will be prompted for channel information. Wait until the cursor is flashing then press
‘OK’ for the next input or press ‘QUIT’ to finish and get out of the programming mode. All changes
up to that point will be saved. The prompts are as follows:
TX Frequency
Enter the desired transmit frequency using the numeric key pad. If the
frequency entered is not within band limits or not on proper channel
spacing, the frequency will automatically be changed to the closest valid
channel.
RX Frequency
TX PL
Enter the desired receive frequency.
Enter the desired transmit PL tone frequency. After the last digit is pressed
the radio will verify that it is a valid frequency and flash the first cursor
again. Press ‘OK’ at this time. The transceiver supports all standard PL
tones. (Also known as CTCSS tones) TXPL tones are generally used to
open repeaters or in talk groups where the receivers are squelch protected
by PL tones. Enter ‘000.0’ for no tone. PL tones are used by analog mode
only.
RX PL
Enter the desired receive PL tone frequency. Enter ‘000.0’ no tone – carrier
squelch operation.
TX DPL
Enter the desired DPL code. You can not have both a PL and a DPL at the
same time. The one that is entered last will turn the other off. A DPL of 000
means off. DPL codes are also known as DCS codes.
RX DPL
TX NAC
Enter the receive DPL code as above.
Enter the desired transmit P25 NAC code if using digital, otherwise just
press ‘OK’. The code is hexadecimal therefore the letters A to F could also
be used. Press the ‘A-F’ soft key to use buttons 1-6 as A-F. A NAC or
Network Access Code is used like PL tones but are only used by P25
(digital) mode. A value of 293 is considered to be the standard code for
open channel.
RX NAC
RX TYPE
Enter the desired receive P25 NAC code as above.
Select the receive mode using the UP and DN keys – Analog, digital or
mixed. The mixed mode will allow the receiver to decode analog and P25
digital signals as needed.
TX TYPE
This prompt will only come up if you selected mixed for RX. Select analog
or digital.
BANDWIDTH
Select 12.5, 20.0 or 25.0 kHz using the UP and DN keys. Bandwidth may
also be called ‘Channel Spacing’.
CHANNEL NAME
Use the UP and DN keys to scroll to the desired letter and press the NXT
soft key to get to the next character. Press ‘OK’ when done. There will be a
delay while the channel is saved, then the display will return to normal.

2.21 VHF LOW BAND (BAND 5) OPERATION – Analog Module Variances
Band 5 is an analogue only, VHF AM transceiver. Operation of band 5 differs slightly from the
others in the following ways:
1) There are only 3 soft key menu items available:
FPP Allows programming of a channel as described in the above section minus the
steps required for digital operation (NAC or TYPE). Wide and Narrow band
channel spacing is selectable even though there is no such allocation on low
band at this time.
SCAN Selecting this soft key will start band 5 scanning the channels in the scan list.
2) PC Uploading and Downloading channels to band 5 is accomplished using Technisonic’s
MultiTDP software which is supplied on a CD with the TDFM-7300-3 and from the TIL
web site. (www.til.ca) The files are compatible with those used on our TFM-550 model.
The same programming cable as is used for bands 1 through 4 is required. (047365-1)
For PC programming the TDFM-7300-3 must be put in to “PCDL Mode” via the function
menu. Otherwise the MultiTDP software will not be able to communicate with Band 5.
3) The F1-F4, ESW and TSW keys have no function on band 5.
4) Band 5 is not included in the cross band repeat or simulcast feature.
5) There is no P25 digital mode. Band 5 is strictly an analog module only.

Type II (II) modules have a wider bandwidth in some cases. If communications are going to occur
in this wider bandwidth area, the antenna with wider coverage should be used.
The antenna should be mounted on the bottom of the aircraft whenever possible possible and
must
not be co-located (kept at a separation distance of more than 20cm from each other when
installed). Also they must be installed in such a way that they always maintain a separation distance of
more than 90cm
with instructions provided with the antenna. Connect the RF cables to the back of the transceiver
using the BNC connectors provided in the installation kit. It is possible to use equivalent 50-ohm
aviation antennas that cover the appropriate bandwidths. For IFR certified aircraft, it is
recommended to use the Sensor Systems antenna for VHF low band along with a low pass filter
to prevent harmonic interference with NAV equipment.

3.19 POST INSTALLATION EMI TEST
PURPOSE
The purpose of this test is to identify any interference that the TDFM-7300-3 transceiver may
cause with existing aircraft systems.
TEST CONDITIONS
The TDFM-7300-3 transceiver should be installed and function tested. The antenna VSWR
should be checked. A forward/reverse power check with an in-line wattmeter should show no
more than 10% reflected power. For the following tests, insure that the output power is set to
high.
METHODOLOGY
Most of the EMI tests can be accomplished on the ground. In some cases flight testing is
required or is easier. If the aircraft is approved for IFR operations, then it is mandatory that
interference between the TDFM-7300-3 transceiver 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/DME receivers should be set to the frequencies indicated and selected for display. If
possible, set up a DME 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. Set the output of the transponder test set to 3db above the output necessary to
achieve 90% reply. If possible set the ADF to a nearby navigation station.
www.til.ca
Modulate the TDFM-7300-3 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). Observe the transponder for any loss of reply or spurious
reply.
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 operation of the TDFM-7300-3 transceiver 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 TDFM-7300-3 unit 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.
PROCEDURE
A. Operate the TDFM-7300-3 transmitter on the following frequency for at least 20 seconds.
Observe the GPS for any degradation in satellite status or availability or flags.

B. Determine if the image frequency for the VHF Comm falls within the range of the TDFM-7300-3. If
so, select a set of frequencies that will cause the TDFM-7300-3 to be set as close as possible to
the image frequency. Any one of the many possible sets will suffice. Record those values in the
spaces provided in the following chart. Modulate the TDFM-7300-3 transmitter on the following
frequencies for at least 20 seconds. Listen for any noise or detected audio signals on the VHF
comm.
Example - Bendix /King KY 196A:
The first IF frequency is 11.4 MHz. The L.O. is above the received frequency (high side injection),
therefore the image frequency is 22.8 MHz above the selected frequency. Set the KY 196A to
120.000 MHz and the TDFM-7300-3 to 142.8000 MHz.

D. The following procedure checks for second harmonic interference to the glide slope receiver from
the TDFM-7300-3. All transceivers produce harmonics (multiples of the wanted frequency) and
while the TDFM-7300-3 far exceeds FCC requirements, interference can still be experienced
depending upon antenna position and separation. Furthermore, harmonics can be generated by
other equipment in the aircraft and the structure of the aircraft where dissimilar metals make
contact or where grounds are isolated, etc. This is also true of aircraft hangars, therefore testing
should be done outside away from any structures where possible.
With a portable glide slope generator, provide enough signal to firmly activate the indicator needle
and hide all flags. Increase the signal level by 3 dB. Modulate the TDFM-7300-3 transmitter on
the following frequencies for at least 20 seconds. Observe the Glide Slope displays. Look for any
movement of flags or needles on the navigation display. If an interference condition is detected,
then the installation will have to be flight tested according to the following procedure. Using the
table below, determine the glide slope frequency based on the localizer frequency of the ILS to be
used. Divide the glide slope frequency by 2 and program into the TDFM-7300-3. Fly the aircraft to
intercept the localizer and glide slope (both needles centered) at 26 nm from the runway.
Transmit on the TDFM-7300-3 for 10 seconds and watch for any deflections or flags. Repeat the
test every 2 nm until the indicators are not affected. If the distance is greater than 18 nm then a
pass shall be recorded. Otherwise the TDFM-7300-3 shall be placarded “Do not transmit while on
ILS approach”.
