INSTALLATION
Antenna Considerations
The FT-2311R is designed foruse with an antennahaving an impedance
near 50 ohms at thè operatingfrequency. For optimumperformance
usea high-quality, carefully designedantenna. The antennashould be
connected at ali timeswhenpower ison,to avoiddamage that can
otherwiseresult if transmission occurs accidentallywhen no antenna
is connected.
Anotherimportantconsideration in installing thè antenna for thè
FT-2311R is thè feedline. For optimumperformance use thè shortest
possible length of thè best qualitycoaxialcableavailable, andbe sure
tousea properlymatching fitting (type-N) for thè jack on thè trans-
ceiver.
Mobile Installation
The FT-2311R must only be installed in cars having a negativeground
electrical System. The transceivershould be located where thè dis-
play,controls and microphone are easily accessible, and should be
securely affixed using thè supplied MMB-33 mobile mounting bracket.
The transceiver may be installed inany positionwithoutadversely
affecting its performance, butit should notbe mountednear a heater
vent or where it could interfere with safeoperation of thè vehicle.
Make surethatplenty of space is provided at thè rear of thè trans-
ceiver so that aircan flow freelyaround thè heatsink.Refer to thè
diagrams on thè facingpage for reversai of thè front panel (if installing
thè transceiver overhead), and installation of thè MMB-33.
(1) Use thè mounting bracket asa tempiale for positioning thè
mounting holes, afterdetermining thè properlocationwith
sufficient clearance for thè transceiver. Usea 4.8mm (3/16")
bit for drilling thè holes. Secure thè bracket with thè screws,
washers and nutssupplied, as shown in Figure 1. (Continued
on page10).

supplied from thè factory), or downward, to accommodatevarious
installation requirements. To reverse thè front panel;
(1) Remove thè ten screws affixing thè topand bottom covers, and
remove thè covers, using care notto strain thè speaker wires.
(2) Remove thè four screws affixing thè front panel, and gently
separate it from thè chassis.
(3) Using care notto pulì on thè interconnectingwiring,turn
thè front panel over, and remount it.

(2) Position thè transceiver in thè bracket so that thè holes in
thè sidepanels are aligned with those in thè sides of thè
bracket, and bolt thè transceiverintopiacewith thè supplied
shortscrews and fiat washers.
Mobile Power Connection
Before connecting thè powercable thè maximum batterychargingvoltage
should be checked to ensurethat it remains below 15V when thè engine
isrun fast. If morethan15V, thè voltageregulator of thè car should
be adjustedbeforeconnecting thè transceiver.
Powerconnectionsshould be madedirectly to thè automobilebattery
using thè supplied cable with 10A in-line fuses.Connection to thè
cigarette lighter or other accessory circuii may cause thè fuse to
blow in that circuii. Connecting thè supplied DC powercable to thè
batteryindependently of thè rest of thè automobile electrical System
will minimize possible ignition noisepickup and excessive supply voltage
dropduringtransmission, while allowing operationwith thè ignition off.
-10-
Do not connect any power to thè transceiver except via thè supplied
fused cable, anddonot attempi to defeat or bypass thè fuses - they
are their to protect youand thè equipment.
Connect thè RED lead of thè power cable to thè POSITIVE (+) bat-
tery terminal, and thè BLACK lead to thè NEGATIVE (-) terminal. If
it is necessary to extend thè power cable, use#14AWGor larger
insulated,strandedcopperwire, andin ali cases use thè minimum
power cable lengthpracticable to keepvoltagedrop minimal.
-WARNING-
NEVER APPLY AG POWER TOTHE REAR PANEL POWER
JACK OFTHE TRANSCEIVER. NEVER CONNECT DC VOLTAGE
OF MORE THAN 15 VOLTS TOTHE POWER JACK. ALWAYS
REPLACE FUSES WITH 10A RATING. FAILURE TO OBSERVE
THESE PRECAUTIONS WILL VOID THE WARRANTY.
The SP-55 ExternalSpeaker isan optional accessory whichallows thè
source of audio from thè transceiver tobe repositioned for optimum
hearing.Especiallypractical for thè noisymobileenvironment, thè
SP-55includes itsown swivel-type mounting bracket, andis available
from yourYaesu dealer. Also available to enhancesafety and mobile
operating convenience are thè YH-1 Headset withminiatureboom
microphone, and thè full size MF-1A3B boommicrophonewith flexible
arm (both of which use thè SB-10 PTT switch).
Base StationInstallation
Mounting feet are supplied for thè transceiverwhenused asa base
station. A power supply capable of providing at least 6A continuously
at 13.8VDC is required for operation from thè AC line, andan external
speaker is recommended. The FP-700 AC powersupply is available
from yourYaesudealer for thispurpose. Use thè fused DC power
cablesuppliedwith thè transceiver for making powerconnections, and
connect thè externalspeaker to thè EXTSP jack on thè rear panel.

Modification for Packet Radio
In thè Europeanversion(B), pin5 of thè MIC jack is wired in parallel
with thè T CALLbutton on thè front panel to accept toneburst acti-
vation from thè microphone.Thisfeature isnot needed for packet
radiooperation,however, sopin5 maybe rewired to provide output
of thè Squelch detect line for packetradio tncs. In otherversion
(not equipped with a T CALLbutton or generator), pin5 is already
wired thisway. The toneburst may stili be activatedafterthis modifi-
cation in Europeanversions, but only by thè T CALLbutton on thè
front panel.
in thè Europeanversion(B),this pinis wired for Burstcontrol
from thè microphone. It canbe modified as follows;
(1) Remove thè ten screws affixing thè topand bottomcovers, and
remove thè covers, using care notto strain thè speakerwires.
(2) Remove thè four screws affixing thè front panel, and gently
separate it from thè chassis,just enough to gain access to
thè CNTL Unit without straining thè wiring.
(3) Cut thè greenwire atpin5 of thè MIC jack on thè rear of
thè CNTL Unit, and carefully tape thè endof thiswire out
of thè way.
(4) Referring to thè diagram below, connect a 200mm wirebetween
thè pointindicate on thè solder side of thè Main Unit and
pin 5 of thè MIC jack.Routethiswire so that it wijl not
interfere with installation of thè covers.

OPERATION
Thischapter describes thè varioustransceiverfunctions in detail.
After studying these descriptions,keep thè FT-2311R Operator'sQuick
ReferenceChartshandy in case you need to refreshyourmemory.
Preliminary Operating Information
Beforeoperating thè transceiver, recheck powersupply and antenna
connections.Never operate thè transceiverwithout an antenna.
Beforeproceeding, please read thè chapter on Controls & Connectors,
if you have not already, to familiarize yourself with thè functions of
thè controls.Noteespecially on page 5 thè description of thè terminol-
ogy usedwhenreferring to thè keys in this manual.
When thè function keys are pressed duringreception, a singlebeep
will sound if thè command is accepted, ora doublé beep if thè command
is invalid.Except for certainspecial cases mentioned later, thè keys
are disabledduringtransmission.
If you havetroublegetting thè transceiver to work as described, see
'In Case of Problems' on page 25.
Squelch Setup
Beforeturning on thè transceiver, set thè SQL control fully coun-
terclockwise. Now rotate thè VOL control outof thè click-stop and
adjust for comfortablevolume on thè noise or received signal. The
BUSY/ON AIR indicator LEO should glow green. Ifa signal is present,
turn thè selector knob to select a frequencywhere only noise is heard.
Rotate thè SQL controlclockwise just to thè pointwhere thè noise is
silenced and thè LEO turnsoff. If thè SQL control isset further
clockwise,sensitivity to weaksignals will be reduced. Now,whenever
-16-
a signal reaches thè receiver that is strongenough to open thè squelch,
thè indicator will glow green.
Notethat while receiving, oneor more bargraph segments may appear
along thè bottom of thè display,indicatingsignalstrength on thè
receivingfrequency.Thisindication isnot affected by thè squelch
setting, so evensquelchedsignals will havesomeindication. Ifyou
notice morethan oneortwo bargraph segments appearingwhile thè
squelch is stili closed, try reducing thè squelchcontrolsetting (if
you want to hearweaksignals).
Transmitting Procedure
Press thè LOW button to select low poweroutput. When you wish to
transmit, wait until thè channel is clear (green LED off), and squeeze
thè PTT switch on thè microphone.Duringtransmission thè BUSY/ON
AIR indicator will glowred, and thè bargraph will now showrelative
transmitterpoweroutput. Release thè PTT switch to receive.
If more power is required, set thè LOW button to thè undepressed
position.However,whenevercommunication is possiblewith low power,
keep thè LOW button depresseti to minimize possibleinterference to
otherstations.
If using a version B (in Europe), press thè T CALLbutton,either on
thè front panel or thè MH-14A8 microphone*, to transmit a 1750 Hz
BurstTone to access repeaters thatrequire it.
If version is modified for packet radio, thè T CALLbutton
on thè microphone is disabled - use thè button on thè front
panel to transmit thè burst tone.

There aretwo ways to select youroperatingfrequency: by turning
thè selector knob, or with thè [UP] and [DOWN] keys. Holding thè
[UP] or [DOWN] key* for morethan i-second will start scanning
(press oneof these keys again to stop).
Channel steps are 12.5 or25kHzin ali versions. To change from one
step size to thè other press [F]+[STEP]*. A small .5kHz digit is dis-
played at thè right endof thè frequency on alternate 12.5 kHz steps.
One-megahertz steps are also available: just press [F] beforeturning
thè selector knob or pressing thè [UP]/[DOWN] keys.
Memory Storage & Recali
The FT-2311R offers ten programmable memorychannels, numbered O
through 9. When in thè Memorymode, thè Memorynumber appears in
thè upperleft corner of thè display. To store a frequency in memory:
(1) Tune to thè desired frequency in thè Dial mode.
(2) Press [F]+[M] (thè Memorynumber will blink) and select thè
desired Memorynumber for Storageusing thè selector knob
or [UP]/[DOVVN] keys,
(3) Press [D/MR] to store thè Dialfrequencyinto thè selected
Memory: thè Memorynumber will disappear, and operation
will continue in thè Dialmode.
If nothinghappenswhen you press a key, seeif there isa
small 'L'at thè lower left corner of thè display. Ifso, press
[F]+ [LOCK] to unlock thè keys.
-18-
Once thè Memorynumber starts blinking in step (2), you have a
maximum of four seconds betweenknob selections or keystrokes until
you press [D/MR] in step (3). Ifyou time out, a memorynumber will
be displayedafter you press [D/MR]. Simply start again at step (2).
Rememberthatwhen you store a memory, any data previously stored
in that memory is erased.
EXAMPLE: to store 1295.000 MHzin channel O
(1) Press [D/MR] once ifa Memorynumber is displayed, to select
thè Dial mode. Then use thè selector knob or [UP] and [DOWN]

The FT-2311R provides a 'standard split' feature, selected by thè [RPT]
key,which activates a pre-programmed offset in both Dial and Memory
modes. In (European)version B thè pre-programmedoffset is35 MHz,
butin version A thè pre-programmedoffset isO MHz. So,to operate
on a standard repeater splitusingversion A,or with an offsetother
than 35MHzin version B, thè standardsplitoffsetmust be reprogram-
med, as follows;
(1) Turn thè transceiver off.
(2) Press and hold thè [RPT] key while turning thè transceiver
back on. '-+' will appear, blinking, along with thè currently
programmedstandard repeater offset.
(3) Use thè [F]keyand selector knob or [UP]/[DOWN] keys to
set thè display to thè standard repeater offsetused in your
area. For example, ifyou need 20MHz standardsplit, press
[F] and turn thè selector knob for 20.000 on thè display (at
thispoint it doesn't matter whether thè split is+ or-).
(4) Press [RPT]again. The '-+' on thè display will stop blinking
as thè displayreturns to what was shownbefore step 1.
Beforeactivating repeater split,tune thè Dialmode to thè frequency
on which you receive thè repeater's signals.Then press [RPT]: once
for '-' shift (to transmit below your receive frequency), and again for
' +' shift (to transmit above your receive frequency). Pressing [RPT]
again will return to simplex. '-'or '+' is displayed at thè upperright
corner whenstandard repeater split is selected, and when thè PTT
switch is pressed to transmit, thè displayedfrequency will shift upor
down, ifin band. If thè resultingtransmitfrequency is outside of thè
ham band, 'Err1 is displayedinstead.
You can check thè frequency tobe used for transmissionwithout
pressing thè PTT switch: just press [REV], to reverse transmit and
receive frequencies (if nothinghappens, thè selected offset is out-of-
band). If both receive and transmitfrequencies arein band, thè '-'or

V displayed at thè upperright will blink, signifying that thè trans-
mit and receive frequencies are reversed. UsingthisREVerse function
also allows youto check thè repeater input frequency tosee if you
can work a particularstation direct (ona simplexfrequency, of course).
Press [REV]again to return to thè originai repeater splitdirection.
Storing a memorywhilestandard repeater split is activated in thè
Dial mode will cause thè offset (amount and direction) tobe stored
along with thè displayedfrequency*.Thenwheneverthatmemory is
recalled, thè stored shift will be active (thè '-'or'+' will be displayed).
The REVerse function cannot be stored in memory,althoughboth
[RPT] and [REV] canbe pressed to temporarilychange repeater oper-
ation on thatmemory: thè new setting will notbe stored. Repeater
shift functions can also be activated whileoperating on simplex memo-
ries, if required.
Non-Standard Repeater Splits
Memories O through 6 can also store an independenttransmitfrequency,
for operation on repeaters with non-standardshift. Todo this, first
storè thè receive frequency as described previously.Thenretune thè
Dial to thè desiredtransmitfrequency, and repeat thè Storage procedure,
but this time hold thè PTT switch at thè last step (when you press
[D/MR] thè last timewhile thè Memorynumber is blinking). Now
when you recali thè memory, '-+' will be displayed together at thè
upperright. The [REV] key will function as describedabove, but pres-
sing thè [RPT] key will disable thè non-standardsplit and make thè
channel simplex.Pressing[RPT]again will activate thè currentlypro-
grammed standardsplitoffset (in piace of thè independenttransmit
When memories O through 6 are stored withstandard repeater
offset, they will retain thè offsetwhich was pre-programmed
at thè timethey are stored. If thè standardoffset isre-
programmed, these memories will not "know" about it unless
thè [RPT] keyis used, or thè memories are restored again
from thè Dialmode.

frequency). To return to thè odd split press [D/MR] twice, to quit
and then recali thè memory again.
Scanning
Beforestarting thè scanner make sure thè SQL control issetto squelch
off thè noise ona clear channel. Two different modes of scanning
are available:bandscanning or memoryscanning. In bothmodes, scan-
ning is manually activated and deactivated by thè [UP] or [DOWN]
key.Just press and hold thè keyfor morethan ì-second to start thè
scanner. If thè transceiver isin thè Dial mode,bandscanning will
result. Ifa memorynumber is displayed, thè transceiver isin thè
Memory mode, and only prestored memories will be scanned.
The scanner is preset at thè factory to pause forupto five seconds
onany channelwhere a signal is found strongenough to open thè
squelch, and thenresuméscanning(this is SCANmode A).Ifyou
prefer to have thè scanner stay paused ona channel (until two seconds
after thè channel becomes clear),move thè SCANmode selector switch
inside thè top cover to position B.See thè photo below.

To stop thè scanner, press anyoneof [UP], [DOWN], [D/MR] or thè
PTT switch.

For memoryscanning, itis sometimes useful tobe able to scan only
certain memories. Youcan 'hide1 any memoryfrom thè scanner (except
Memory 0) withouterasing it altogether: press [F]+[M], select thè
memory to hide, and presS [F]+[M] again while thè Memorynumber is
blinking. The display reverts to memory O,and thè hiddenmemory
canno longer be selected or scanned.
To unmask a hiddenmemory, just repeat thè same steps you took to
hide it: press [F]+ [M], select thè Memorynumber to unmask, and press
[F]+[M] again.
Priority ChannelMonitoring
The Priorityfunctionallowsperiodicchecking for activity onany
memorywhileoperating on thè Dialfrequency, or checking of Memory
1 whileoperating on other memories.When a signal appears on thè
prioritymemorywhilereceiving,operation will automatically shift to
that memory, forupto five seconds (in SCANmode A),orforas
long asa carrier is received (SCANmode B,see page 22). Ifyou
transmitwhile thè squelch is open on thè prioritymemory,priority
monitoring is cancelled and operation stays on thè prioritymemory.
The squelchmustfirst be preset, and thè frequency tobe monitored
stored ina memory(Memory 1 ifyou will be operating on other mem-
ories whilemonitoring). Press [D/MR] to operate on thè Dial, or else
select thè memory you want to operate on,and then press [F]+[PRI].
A 'P' will appear in thè memorywindow at thè upper left corner of
thè display, and about every five seconds thè displayedfrequency will
shift to thè prioritymemorybriefly as thè receiver checks fora signal.
As long asno signal appears on thè prioritymemory, youcan tune,
transmit and receive on thè Dial, or select and operate on other mem-
ories (although thè memorynumber isnot displayed). Ifa station you
wish to talk with appears on thè prioritymemory, press thè PTT switch
momentarily while receiving his signal, to stop prioritychecking.
Otherwise, to cancel prioritymonitoring, press [D/MR].

Tone SquelchOperation
The FT-2311R canbe used to silentlymonitor for calls on busy chan-
nels when thè optional FTS-12 ToneSquelch Unit is installed. The
encode function superimposes a subaudibletone (ata frequency too low
tobe heard) on yourtransmittedcarrier, while thè decode function
monitors thè detectedreceiveraudiothrough a narrow filler at thè
same subaudiblefrequency,keeping thè squelchclosed until a signal
appears with a matchingtonesuperimposed. Installation instructions
areon page 14.
To check orset thè tonefrequency select thè Dial mode, and press
[F]+[T SET]. The tonefrequency will be displayed (in Hz), with a leading
zero if thattoneselection isa high-Q type*. To change thè tone
frequency, rotate thè selector knob or press[UP] or [DOWN] until
thè displayshows thè tonefrequency you require (thè display will
step through thè standard EIA tones). Press [TONE] to return to thè
operatingfrequencydisplaywhen thè tone frequency is selected.
To activate tonesquelchfunctions press [TONE]. With one press,
'ENC' (encode) will be displayed and thè tonegenerator will be activated
for transmission. Press [TONE]again and both 'ENC' and 'DEC' (decode)
will be displayedtogether as tonesquelch is activated for bothtrans-
mission and reception (only signalssending thè matchingtonefrequency
will open thè squelch).Pressing[TONE]oncemoredisablestonesquelch
features.
Once you have thè tonesquelch setup thè wayyou want it,youcan
store itin memory (or thè cali channel) by pressing [F]+ [M], select
thè memory to store, and press [D/MR]. Afterwards, to change a
setting stored in memory,justrecali thè memory,- reset thè tone
frequency or function, and press [F]+[M] and [D/MR].
*If nothinghappens, thè FTS-12 isnot installed.

IN CASE OF PROBLEMS
Basic FT-2311R operation isnot complicated, butitisnot hard to
get lost when firstgettingacquainted with thè display and keypad
functions, or whenlearning touse some of thè finer features like
split-frequency memories. If thè display shows nothing at ali, check
thè powerswitch(VOLcontrol), and thè power supply connections.
Fortunately, thè displayincludesenoughsymbols and function indicators
to let you know what is going onas long as power is applied, soit
is'well worthwhile to study thè displaydiagram on page 6 carefully.
For example, if thè frequencydisplaychangesunexpectedlywhen you
transmit (orif 'Err'appears),check fora small ' + ' or '-' at thè upper
right-hand corner. Also, if only a few seemingly non-sensical digits
appear,press[TONE] to disable thè tonesquelchsettingfeature.
Attempting an illegaicommand usually causes two beeps to sound. If
pressing a key appears todo nothing,check fora small 'L'at thè
lower left, whichindicates if thè keypad is locked. Ifso, press
[F]+[LOCK] to unlock thè keys. If thè 'L' isnot there, press[D/MR],
which will terminate any partiallyenteredcommands. Ifyou stilicannot
enterdata,check thè ONAIR indicator toseeifitis red,indicating
that thè transceiver is transmitting. Releasing thè PTT switchshould
return thè setto receive. If stilinothinghappens,switch thè
transceiveroff, and thenback on.
To avoidinadvertent key presses during standbyoperation,activate
thè keypad lock (press [F]+ [LOCK]). Youcan stili changechannels
with thè selector knob when thè keys are locked.Remember toset
thè lockback off(by thè samekeystrokes)when you wish to enter data.
If thè transceiver stili isn't operating asyou believe it shouldafter
studying thè Operationsection,remove thè top cover and reset thè
memories by shorting thè reset terminals(pictured on page15).
