General Information
This
section contains a basic
description
of
the
KX
99
Transceiver
as well as suggestions and factors to
consider before using the KX
99.
Close adherence
to
these sugges-
tions
will
assure a more satisfactory
performance from the equipment.
Equipment Description
The KX
99
is a 760 channel,
hand-held VHF aircraft communica-
tions transceiver with a
1.5
watt
transmitter output. In addition, the
KX
99
is capable of receiving
200
Nav
channels and all
7
NOAA Weather
Radio Broadcast channels. While
audio is received on all
200
Nav channels, localizer information is not processed on the 40 localizer frequencies. VOR information is processed and displayed on the liquid crystal display (LCD) in either a radial, bearing,
or
Course Deviation Indicator (CDI) left-right information format. The KX
99
contains a single receiver.
Therefore,
it
cannot perform the
COMM function and the
NAV
function
simultaneously.
The unit is powered by a self­contained battery pack. Frequencies and features are entered via the keypad on the front of the unit. The keypad and display may be illumina­ted for night use. Power On/Off, volume, squelch sensitivity, keyboard lockout, and transmitter lockout controls are located on the top of the unit. Jacks for headphone and microphone are also located on the top of the unit. The flexible antenna may also be removed
so
the unit may
be used with an external antenna.
License Requirements
If
the KX
99
Transceiver is
to
be utilized in an aircraft an Aircraft Radio Station License is required.
If
the
transceiver is
to
be used as a ground station, then a Ground Station Authorization is required. Included with the KX
99
are a FCC Form
404,
Application for Aircraft Radio Station License and a FCC Form 406, Application for Ground Station Authorization in the Aviation Services. Additional copies may be obtain from your nearest FCC Field Office.
This equipment has been
accepted by the FCC and entered on
their list of Type Accepted Equipment
as King Radio Corporation Model KX
99,
(ASY7BL KX
99).
Caution:
The VHF transmitter in this equipment is guaranteed to meet FCC acceptance over the operating femperature range only when a King crystal is used in the stabilized master oscillator. Use of other than
a
King crystal is considered an unauthorized modification, and will void the warranty.

Antenna Requirements
The flexible antenna that is included with the KX 99 is very convenient and may be used for both
communications and navigation
purposes. However a more efficient antenna may be required for some applications. For maximum utilization of the
KX
99 inside an aircraft, automobile or other metal enclosure, an external COMM antenna should be
used for communications and an external NAV antenna should be used for navigation. An external communi-
cations antenna will noticeably
improve the reception and transmis-
sion
of communication radio signals; however, it is not recommended for receiving navigation signals. The use
of
a horizontal type navigation antenna will improve the reception and the directional characteristics
of
the navigation signal but it is not recommended for communications transmissions from the KX 99. The
BNC type connector, located on the
top
of
the unit, is standard for use on
aircraft radios and antennas
so
little difficulty should be encountered when connecting
to
an existing aircraft communications or navigation an­tenna.
VOR navigation signals are received best by a horizontal antenna while communications signals are received best by a vertical antenna. This is a good point to keep in mind when trying
to
receive weak signals. When using the flexible antenna in the cockpit
or
an automobile,
try
to
place the antenna in the center of a window which is facing the station you are
trying
to
receive. Remember,
if
the
received station is weak and noisy, that station is not likely to hear your transmission. Obtain the best received signal before attempting to call the
station.
When the KX 99 is
to
be used as
an emergency backup Comm or Nav
radio in an aircraft, one
or two
antenna
adapters
(P/N
071
-01443-0001)
may
be installed
to
easily connect the
KX 99 to the existing aircraft antennas.
See
diagram
below.

Nickel Cadmium (NiCad) Battery Pack
The standard power source
supplied with the
KX
99
is
a
9.6
volt,
720
mA hour, rechargeable nickel­cadmium battery pack. The battery that is shipped with the
KX
99 will not be fully charged and should be charged prior
to
use.
If possible, the battery should be
fully discharged before recharging. This will maintain the maximum useful charge in the battery and avoid "memory" problems associated with this type battery.
A
characteristic of NiCad batteries is that they do not hold their charge for long periods of
time such as an alkaline battery does.
Caution:
Do
not store a discharged battery pack. Battery cell polarity may reverse making it impossible for the battery
to
fully recharge.
Do
not store a battery pack where it might be accidentally shorted. The current capability is tremendous.
Do
not crush or disassemble a NiCad battery pack. There are toxic
chemicals inside.
Do
not dispose of the battery pack in a fire. It may explode.
Do
not exceed the recommended quick charge current. Use only the
approved chargers.
The
KX
99 comes standard with
a trickle charger capable
of
operating
on either
11
5V or 230V.
To
charge the battery; plug the charger module into an appropriate wall outlet and plug the other end into the connector marked "CHRG which is located on top of the
KX
99.
It
takes approxi-
mately
12
hours
to
fully charge the
NiCad battery pack.
Caution:
To avoid possible damage
to
the KX
99
make absolutely certain
that the
7
15V/230V
select switch
located
on
the trickle charger is in the
correct position for the voltage
to
be
used.
The amount of time that the
NiCad battery pack will power the
KX
99 on one charge depends on a
number of factors:
The duty cycle (amount
of
time the unit is transmitting versus time receiving
a
signal versus squelched standby operation). Transmitting discharges the battery fastest. The volume level of the received signal. The temperature.
A
colder battery
will not last as long.
'
The following table shows the approximate life of a fully charged NiCad battery at several different duty cycles with midlevel volume and the battery at room temperature.

Alkaline Battery Pack
An optional replaceable cell alkaline battery pack is available for the
KX
99.
Alkaline batteries are used for radios that are maintained for emergency purposes because they have extremely long shelf life and no maintenance is required.
ALKALINE
BATTERY PACKS ARE NOT TO
BE
RECHARGED!

The alkaline battery pack holds
8
'AA"
size cells. To gain access
to
the
8
cells, first remove the battery pack
from the KX
99
(see below). Next, with one hand holding the outside of the battery pack case, use the other hand
to
press down firmly on the center hub on the top of the case. The battery cell holder will slide out the bottom of the case.
Alkaline battery life will be
approximately the same as that
of
a
NiCad for a
90%
STBY,
5%
REC
and
5%
TX
duty cycle. However, alkaline
batttery life will be considerably less
than a NiCad at higher duty cycles
and considerably greater than a NiCad at lower duty cycles.
Battery Pack Installation and Removal
To install the battery pack (either NiCad or alkaline), locate the center hub on the top of the battery pack into
the recess on the bottom of the unit.
Position the battery pack at a
30"
offset
so
that the two metal studs on
the battery pack go into their respec-
tive recesses on the bottom
of
the
unit. Apply upward pressure
to
the
pack while twisting the pack
so
that
it's sides are flush with the sides of
the unit. The metal tab on the side of the unit will lock the pack into position.
To
remove the battery, turn the
radio
off.
Press up on the metal tab on
the side of the unit while twisting the
battery pack
30"
and remove it from
the radio.
See
figure
below.
Low

The KX
99
has a low battery
indicator "beep" tone that
will
signal
the user when the battery
is
almost
unusable.
HeadphonelMicrophone Adapter
External headphone and
microphone jacks are located on top
of the
KX
99.
The supplied head­phone/microphone adapter allows standard aircraft headphones and microphones
to
be used with the
KX
99.
The clip on the adapter should
be connected
to
the protruding attach
point
on
the right side of the unit to
provide strain relief.
If
a headset with a boom mike is used, the transmit key button on the side of the
KX
99
may
be used
to
key the transmitter. A separate push-to-talk switch may also be used with the headphonelmicro­phone adapter.
