2.2 OPERATING LOCATION
As with anysolid
stateelectronic
equipment,
theTS-53O
should be kept from extremes
of heat and humiditv.
Choose
anoperatinglocation
thatisdryand
cool,and
avoid
operatingthetransceiver
indirectsunlight.
Also,allow
at
least
3 inches clearance
between
the backof the equip-
ment to any object. This space
allowsan adequate
air
flow
fromtheventilating
fan
to keepthe
transceiver
cool.
CAUTION:

2.4 MICROPHONE
Attach the microphone
connector
to a suitable
micro-
phone,
as shown in Figure
2-1
. Besure the microphone
PTTswitch is separate
from the microphone
circuit,as
shown. lt should
be notedthat a microphone
with a 3P
plug
usingacommon
ground
terminal
should
notbeused.
Themicrophone
input
isdesigned
for 50OO- 50kOmi-
crophones.
The choiceof microphone
is important
for
good
speech
quality,
andshould
begiven
seriousconsidera-
tion. The crystal
lattice
filterin
thetransceiver
provides
all
the restriction
necessary
on audio
response,
andfurther
restriction
inthe
microphone
is
not
required.
lt ismoreim-
portant
to haveamicrophone
withasmooth,
flatresponse
throughout
thespeech
range.
Follow the microohone
manufacturer's
instructions
for
connecting
themicrophone
cableto the plug.
With many
microphones,
thepush-to-talk
switch
mustbepressed
to
makemicrophone
audio
available.
For
VOXoperation,
this
unwanted
feature
maybeeliminated,
if.desired,
by open-
ing
themicrophone
case
and
permanently
connecting
the
contacts
whichcontrol
themicrophone
audio.
Standard
microphone
sensitivity
is within the range
of
-50 dB
to -60 dB.lfa
microphone
havinga
highersen-
sitivity
is used,
the ALC andcompressor
circuits
will not
function
properly.
Inthiscase,
insert

tenuator

control
setting
is 12 o'clock.
lf youmustrunthiscontrol
at I o'-
clock
orless,useanattenuator.
2.5KEY
lf CW operation
isdesired,
connect
a key
to theKEY
jack.
Use
shielded
cable,and
a standard
(mono
or 2P)
phone
plug.
2.6 EXTERNAL SPEAKER AND
HEADPHONES
Receive
audiooutput
fromthe
TS-530is 1.5wattsat4 to
16 ohms.TheTS-530 hasa built-in
speaker
jackon the
rearpanel.The speaker
may be an 8-ohm permanent-
magnet
type,
4 inches
or'larger.
The internalspeaker
is
disconnected
when an external
speaker
is used. Head-
phones should also be 4 to 'l
6 ohms impedance
or
greater.
When headphones
are connected
to the front-
panel
PHONES
jack,
thespeaker
isdisabled.
2.7GROUND
Toorevent
electricshock,
and
reduce
the
possibility
ofTVI
and BCl,connect
the transceiver
to a good
earth
ground
through
asshortand
heavya leadas
possible.
2.8 ANTENNA
Anyof thecommon
antenna
systems
designed
for useon
the high
frequencyamateur
bands
maybe used
with the
TS-530
provided
theinput
impgdance
ofthetransmission
line
is
notoutside
thecapability
ofthebi-output
m3tching
network.The transmission
lineshould
be coaxial
cable.
An antenna
system
which
showsastanding
wave
ratioof
lessthan2:1
when
using
5Oor
75 ohmcoaxial
transmis-
sion
line,orasystem
that
resultsin a
transmission
line
in-
put impedance
that is essentially
resistive,andbetween
15 and 2OOohms will take powerfrom the transceiver
with littledifficulty.
lf openwireof balanced
type trans-
mission
lineisused
with theantenna,
a suitable
antenna
tuner
with balun
isrecommended
between
the
transceiver
and
thefeedline.
Methods
of construction
andoperating
such
tunersaredescribed
in detail
in the ARRL
Antenna
Handbook,and
similar
publications.Foroperation
on the
160,75 and
4Ometer
bands,asimple
dipoleantenna,
cut
to resonance
in the most used
portion
of the bands,
will
perform
satisfactorily.
Foroperation
of thetransceiver
on
the 10, 15 and20 meterbands,theefficiency
of thesta-
tion will be greatly
increased
if a gooddirectional
rotary
antenna
isused.Remember
thateven

CAUTION:
Protect
