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).

Front Panel Reversai
The front panel maybe installed so that itis angledeitherupward (as
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.
(4) Replace thè topand bottom covers (now also reversed) and their
ten screws.

(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.

Racket Radio TNC Interconnections
Most popularpacketradio tncs canbe connected to thè MIC jack of
thè FT-2311R as follows:

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.
(5) Replace thè front panel andits four screws, and then thè
topand bottom covers and their ten screws.
