General Information
This section contains a basic
description
of the KX 99 Transceiver
as well as suggestions and factors to
consider beforeusingthe KX
99.
Close adherence to thesesugges-
tions
will assure a moresatisfactory
performancefrom the equipment.
EquipmentDescription
The KX 99 isa 760 channel,
hand-heldVHF aircraftcommunica-
tions transceiver with a
1.5 watt
transmitter output. Inaddition, the
KX
99 iscapableof receiving 200 Nav
channels andall
7 NOAA Weather
Radio Broadcast channels. While
audio is receivedon all 200 Nav
channels, localizerinformationis not
processedon the 40 localizer
frequencies. VOR informationis
processedand displayedon the liquid
crystaldisplay(LCD) ineither a radial,
bearing,
or Course DeviationIndicator
(CDI) left-rightinformationformat.The
KX
99 containsa single receiver.
Therefore, it cannotperform the
COMMfunction and the NAV function
simultaneously.
The unit ispoweredby a self-
containedbatterypack. Frequencies
andfeatures are enteredvia the
keypadon the front of the unit.The
keypadanddisplay may be illumina-
tedfor night use. Power On/Off,
volume, squelch sensitivity,keyboard
lockout, and transmitter lockout
controlsare locatedon the top of the
unit. Jacks for headphone and
microphone are also locatedonthe
top of the unit. The flexibleantenna
may also be removed
so the unit may
be usedwith an external antenna.
License Requirements
If the KX 99 Transceiveris to be
utilizedinan aircraftan Aircraft Radio
StationLicenseis required.
If the
transceiveris to be usedas a ground
station, then a GroundStation
Authorizationis required. Included
with the KX
99 are a FCC Form 404,
Application for Aircraft RadioStation
License anda FCC Form406,
Application for GroundStation
Authorizationinthe Aviation Services.
Additionalcopiesmay be obtainfrom
your nearestFCC FieldOffice.
This equipment hasbeen
acceptedby the FCC and enteredon
their listof Type Accepted Equipment
as King Radio CorporationModel
KX 99, (ASY7BLKX 99).
Caution: The VHF transmitter in this
equipment is guaranteed to meet
FCCacceptanceover the operating
femperaturerange only whena King
crystal is used in the stabilizedmaster
oscillator. Use of other than
a King
crystal is consideredan unauthorized
modification,and will void the
warranty.

Antenna Requirements
The flexible antenna that is
includedwiththe KX 99 isvery
convenientand may be usedfor both
communicationsand navigation
purposes. However a moreefficient
antenna may be requiredfor some
applications. For maximum utilization
of the
KX 99 insidean aircraft,
automobileor other metalenclosure,
an externalCOMM antennashould be
used for communicationsand an
externalNAV antenna should be used
for navigation.An externalcommuni-
cationsantennawill noticeably
improvethe receptionandtransmis-
sion of communicationradiosignals;
however,it is not recommendedfor
receivingnavigationsignals.The use
of a horizontaltype navigation
antennawill improvethe reception
andthe directionalcharacteristics
of
the navigationsignal but it isnot
recommendedfor communications
transmissionsfrom the KX 99. The
BNCtype connector,locatedonthe
top
of the unit, isstandardfor useon
aircraftradios and antennas
so little
difficultyshould beencounteredwhen
connecting to an existingaircraft
communicationsor navigationan-
tenna.
VOR navigationsignalsare
receivedbestby a horizontalantenna
while communications signals are
receivedbestby a verticalantenna.
This isa good pointto keep inmind
when trying
to receiveweak signals.
When usingthe flexibleantenna inthe
cockpit
or an automobile, try to place
the antenna inthe center of awindow
which isfacingthe stationyou are
trying
to receive.Remember, if the
receivedstationisweak and noisy,
that stationisnotlikelyto hear your
transmission.Obtainthe best received
signal beforeattemptingto callthe
station.
When the KX 99 is
to be used as
an emergency backupComm or Nav
radioinan aircraft,one
or two antenna
adapters (P/N 071 -01443-0001) may
be installed
to easily connectthe
KX 99 to the existingaircraftantennas.
See diagram below.

Nickel Cadmium (NiCad)
Battery Pack
The standard power source
suppliedwith the
KX 99 is a 9.6 volt,
720 mA hour, rechargeable nickel-
cadmium batterypack. The battery
that isshippedwith the
KX 99 will not
befully charged andshouldbe
charged prior
to use.
If possible, the battery shouldbe
fully dischargedbeforerecharging.
This will maintainthe maximum useful
charge inthe batteryandavoid
"memory"problemsassociatedwith
thistype battery.
A characteristicof
NiCadbatteriesisthat they do not
holdtheir chargefor longperiodsof
time such as an alkalinebatterydoes.
Caution:
Do notstore a dischargedbattery
pack. Battery cellpolarity may
reverse making it impossiblefor the
battery
to fullyrecharge.
Do not storea battery pack whereit
might be accidentallyshorted. The
current capabilityis tremendous.
Do not crushor disassemblea
NiCad battery pack. Thereare toxic
chemicals inside.
Do not disposeof thebatterypack
in a fire. It may explode.
Do not exceed the recommended
quick charge current.Useonly the
approved chargers.
The KX 99 comes standardwith
atricklecharger capable
of operating
on either 11 5V or 230V. To charge
the battery; plugthe charger module
intoan appropriate wall outletand
plugthe other endintothe connector
marked"CHRGwhichislocatedon
top of the
KX 99. It takes approxi-
mately
12 hours to fully charge the
NiCadbatterypack.
Caution: Toavoidpossible damage
to theKX 99 make absolutelycertain
that the
7 15V/230V selectswitch
located
on thetricklechargeris in the
correctposition for the voltage
to be
used.
The amount of time that the
NiCadbatterypack will power the
KX 99 on one chargedependson a
number of factors:
The dutycycle (amount
of timethe
unit istransmittingversustime
receiving
a signalversus squelched
standby operation).Transmitting
dischargesthe batteryfastest.
The volume levelof the received
signal.
The temperature.
A colder battery
will not last as long.

The transmit frequency of 122.10MHz
may now beentered. Depressthe
keysonthe keyboardinthe following
order:
I] +12) +Fl +Fl +I1
Two seconds after a valid
frequency has beenentered the
display will revertback to the receive
frequency and any appropriate
CDI
indication. The transmit frequency
may bechecked by momentarily
depressing the MikeKey buttonon
the side of the unit. The frequency
window will display the transmit
frequency any time the unit
is
transmitting.
Scan Modes
The scan modesallow the user
to sequentially stepthrough a group
of frequencies to find an active
frequency. When atransmissionis
received, the radiowill stop scanning
and remainonthat frequency untilthe
activity stops. After the frequency has
been inactive for 2 seconds, the scan
process
will resume. There are 2 scan
modes, memoryscan and frequency

beenactivated.
The Memory Scan mode can be
cancelledby againpressingthe MEM
key followedby the
SCN key.

Memory Lockout
Memory Lockoutappliesonly to
the Memory Scan mode and notthe
FrequencyScan mode. Any of the 10
Memory Locationscan be omitted
fromthe scanningsequence. The
memory locationis first displayedin
the frequencywindow andthen
lockedout. For example,
to lockout
the frequencystored in Memory
Location2 depressthe keys on the
keyboardinthe followingorder:
I 1

bedisplayedon the left handsideof
the display indicatingthat the
frequency stored in Memory Location
2 is beingdisplayed. Continue to
depress the keyson the keyboardin
the followingorder:
An Lwill now appear inthe lower
rightcorner of the display
to indicate
that the frequency storedin Memory
Location
2 has beenlockedout of the
scan sequence.
To restorea locked
out Memory Location
to the Memory
Scan sequence, performthe same
sequence as above andthe memory
locationwill be returned to the scan
sequence andthe "L" will be removed
from the display.
FrequencyScan Mode
The FrequencyScan mode
scansthe frequencyrangein25 KHz
stepsbetweenthe frequencystored
in Memory Location 1and the
frequency storedin Memory Location
9. Only COMM frequencies
(118.00MHz-136.975MHz) may be
scannedinthe Frequency Scan
mode. For example
to scanthe
frequencyrangeof 120.00 MHz to
124.50MH2, 120.00 must first be
stored inMemory Location 1and
124.50 mustbestored in Memory
Location 9. Refer to the section
entitled"ProgrammingMemory
Locations
1-9 for storing 120.00 and
124.50 inthe appropriatememory
locations. After the frequencies have
beenstored, depress the following
key on the keyboard:
120.00
An S will appear inthe bottom
right corner of the display indicating
the Scan mode has beeninitiated.
The unitwill start scanning through
the frequency range in25KHz steps
to 124.50MHz. When the frequency
window gets
to 124.50itwill resetand
start countingat 120.00 again.

To exitthe Frequency Scan
mode at any time, simply depress the
SCN buttonon the keyboardagain. If
the unit is keyedduringscan opera-
tion the scan optionwill bedisabled
andthe unitwill remain tuned
to the
frequency itwas tuned
to when the
unit was keyed.
If either Memory Location 1or
Memory Location9 contains a
navigation frequency (108.00 MHz
to
117.95MHz) the scan limitwill bethe
appropriate end of the communica-
tions band. For example,
if Memory
Location1has a navigationfrequency
storedinit the scanwill beginat
118.00MHz and
if Memory Location9
has a navigationfrequency storedin it
the scanwill resetwhen it reaches
136.975MHz (1 35.975MHz on KPN
069-1026-00versionunits).
Priority Mode
When the Priority mode of the
KX 99 isenabled the unit
will check
the Priority frequency once a second
for any activity.
If any activityis
presenton the Priority frequency the
receiver
will stay tuned to the Priority
frequency untilthere is noactivityfor
2 seconds. Keyingthe transmitter
within two seconds after the last
transmission onthe Priority frequency
will disable the Prioritymode. The
Priority mode cannot be enabled
if a
navigation frequency iscurrently
displayed. (1 08.00 MHz to
117.95MHz). A navigationfrequency
cannot beprogrammed as the Priority
frequency.
To enable the prioritymode
press the followingkey onthe
keyboard:
The frequency window will now
display the frequency that was selec-
ted andwill displaythe Priority Fre-
quency once a second. The Priority
annunciationPwill also be displayed
on the left sideof the display.
To exit
the Priority mode at any time, simply
depressthe PRIkey on the keyboard
again.
If there is any activityon the
Priority channelthe unitwill remain
tuned
to the Priorityfrequency for two
seconds after alltransmissionactivity
on the Priorityfrequency hasstopped.
If the transmitteris keyedwithin two
seconds after receivinga transmission
on the Priorityfrequen-cythe unitwill
remaintuned to the Priorityfrequency
andthe Prioritymode will bedisabled.
It may be reenabledat any time by
depressingthe PRIbuttonagain.
