Display
The display shows the primary and standby frequencies and a series of icons to
indicate the operating mode of the radio.
The primary frequency is on the left and the standby frequency is on the right
half of the screen. The TX icon shows that the radio is transmitting. An RX icon
shows that the frequency is active and the audio will be heard through the
headphone and speaker outputs. The standby frequency will only be received
during the MONITOR function which is indicated by a +2 icon when active.
The top right hand corner indicates what frequency step size is selected.

On/Off, Volume and Squelch Knob
The left hand knob controls the power to the VHF radio, adjusts the audio
volume, and controls the squelch. Turning this knob clockwise will switch on
the radio and then increase the volume. Turning anticlockwise will reduce the
volume and eventually will click off.
Pressing this knob toggles the automatic squelch on and off, which can be
used to listen for faint stations and as a simple audio test.
Tuning Knobs

Tuning Knobs
The right hand concentric knobs are used to tune the radio. The large knob
adjusts the MHz portion of the standby frequency, and the smaller knob
adjusts the kHz portion of the standby frequency.

Pressing the end of the small knob changes the channel spacing that the small
knob operates through. If the radio is configured for 8.33 kHz operation, the
steps toggle between 8.33 kHz channels and 25 kHz channels. If the radio is
configured only for 25 kHz operation, the steps toggle between 25 kHz and 50
kHz channels.
Changing the step size does not change the behaviour of the radio, only the
tuning knob step size – it helps to quickly tune a frequency.

MON Button
The VHF radio includes a dual-frequency listen feature; pressing the MON
button toggles this feature on and off.
When the monitor is active, a +2 icon appears next to the standby frequency,
and the radio will scan between the active and standby frequencies listening
for transmissions. The primary channel has priority – a transmission on the
primary channel will interrupt the secondary channel. As an aid to identifying
which channel is active, the RX icon will light next to the active channel and
the secondary channel will appear slightly quieter than the primary. If your
radio is wired for stereo and you are using a stereo headset, the secondary
channel will also appear to be to the right of the primary channel.
This is useful in an aircraft with only a single radio since it allows you, for
example, to copy the ATIS whilst maintaining a listening watch on the ATC
frequency.

The VHF radio includes a digital audio recorder. Pressing the PLAY button will
automatically replay the previous transmission received from ATC. During
playback the PB icon will be displayed on the screen.
If a new transmission is received during playback, the playback is cancelled
and the live transmission will be heard instead.

The EMER button gives quick access to the standard emergency frequency of

mutes the music input and the auxiliary audio input, and if the volume is set to
a low level it turns it up.

you are operating in an area with no 8.33 kHz service,
turning off the 8.33 kHz channels allows quicker turning
of 25 kHz and 50 kHz steps.

General Low Temperature Operation
The TY96/TY97 is certified to operate correctly down to -20°C, but at low
temperatures the controller display may be impaired. On a cold day you may
need to wait for the cockpit to warm up to ensure normal operation.
Warning Messages

Warning Messages
If the VHF radio detects a problem, the screen will indicate WARNING and a
brief statement of the problem. Depending on the nature of the problem,
your VHF radio may not be working properly. Note the message on the screen
and pass that information to your avionics maintenance organisation. Press
the flip-flop button to clear the message.
The following warnings may be seen:
Radio Hot The radio is overheating.
Stuck Mic A PTT switch has been closed for more than 35 seconds and
the transmitter has stopped to avoid blocking the channel.
Low Voltage The aircraft power input is below 10 volts (TY96) or 16 volts
(TY97
).
Ant Fault There is a problem with the aircraft antenna. The radio will
still try to transmit, but you may not be heard.
Transmit Fail There is a problem with the transmitter and the radio gave
up trying. You may still be able to receive but not transmit.
Fault Annunciation

If the VHF radio detects a catastrophic internal failure, the screen will indicate
FAULT and a brief statement of the problem. Note the FAULT message at the
bottom of the screen and pass that information to your avionics maintenance
organisation. The fault may be cleared by re-cycling the power to the radio
but if the fault is still present the message will reappear.

Intercom Function
Intercom FunctionIntercom Function
Intercom Function
The TY96/TY97 radio has a built in intercom which can be installed as
permanently engaged or selected via a switch. The intercom is voice activated
and the audio is routed through to both of the headsets. The intercom squelch
and volume can be adjusted independently from the radio function through
the configuration menu.
Frequency Database
Frequency DatabaseFrequency Database
Frequency Database
The radio has up to three databases containing frequencies and station
identifiers. One is stored in the radio and configured by the pilot; it will always
be available. One is a list of the ten most recently used frequencies; it will be
populated automatically as you use the radio. The third is only available if your
radio has been connected to a compatible GPS receiver, and contains
frequencies loaded from the GPS database.
To access these databases press the MEM button. The right hand part of the
screen will be replaced with the database screen which always starts on the
pilot created database.
The large knob moves the highlighted cursor, whilst the small knob selects the
value at the cursor.
Airfield or facility identifiers are in alphabetical order. Scroll through the
identifiers until you find the one that you want. Move the cursor using the
large knob to highlight the station type, for example GND, TWR or APP.
Pressing the MEM button at any time puts the currently selected result into the
standby frequency and returns to the normal operating screen. Pressing the
EN

Flip-Flop button puts the currently selected result into the active frequency
instead, and returns to the normal operating screen.
Recent Frequencies

There is also a memory of the ten most recent frequencies that you have used.
From the initial memory screen, move the cursor using the large knob to
highlight the MEMORY caption, and turn the small knob to select the RECENT
database.
Move the highlight onto the frequency, and you can scroll through the ten
most recently used frequencies.
GPS Database
GPS DatabaseGPS Database
GPS Database
If it has been configured in your aircraft, there is a third database in the radio.
This is loaded by your GPS receiver and will contain airfields appropriate to
your current route of flight.
It is accessed exactly the same way as the built in database, except that you
first select the remote data source using the large knob (to highlight the
database field) and the small knob (to select the GPS data source).
The only difference is that airfield identifiers are usually ordered by how close
they are to your route, rather than alphabetical order.

You can add station identifiers and frequencies to the internal database, which
stores up to 250 entries. To edit the database, go into memory mode by
pressing the MEM button, then press and hold the MEM button for 5 seconds.
The screen will change to highlight the top field which will offer the choice of
EDIT, DELETE, ADD NEW and CANCEL.

To add a new database entry, select ADD NEW, and then press MEM again.
Use the large knob to move the highlighted cursor, and use the small knob to
select characters, numbers or facility type. Pressing the MEM button again
stores the new value, and returns to the normal memory mode.
If you already have entries in the database, you can edit them to change the
details, or you can delete them. To do that, first find the entry that you want to
edit or delete using the normal memory mode. Then, with the entry you want
to change displayed, press and hold the MEM button for 5 seconds. The
choices described earlier will be offered; EDIT, DELETE, ADD NEW or CANCEL.
If you choose EDIT, and press MEM, the cursor can alter characters, numbers or
facility type in the current entry. Pressing MEM will save that changed entry. If
you choose DELETE, and press MEM, the current entry will be deleted.
If you get this far and realise that you did not want to change the database at
all, select CANCEL and then press MEM; you will be returned to the normal
memory mode.
