RECEIVING SSB SIGNALS
There,are,four,types,of,signals,presently,used,for,communications,in,the,Citizens,Band),
FMW,AMW,USBW,and,LSBD,When,the,MODE,switch,on,your,unit,is,placed,in,the,AM,positionW,
only,standard,doubleOsideband,and,in,FM,positionW,only,frequency,deviationW,full,carrier,
signals,will,be,detectedD,An,SSB,signal,may,be,recognized,while,in,the,AM,or,FM,mode,by,
its,characteristic,‘’Donald,Duck’’,sound,and,the,inability,of,the,AM,or,FM,detector,to,produce,
an, intelligible, outputD, The, USB, and, LSB, modes, will, detect, upper, sideband, and, lower,
sideband,respectivelyW,and,standard,AM,signalsD,SSB,reception,differs,from,standard,AM,
reception,in,that,SSB,receiver,does,not,require,a,carrier,or,opposite,sideband,to,produce,
an,intelligible,signalD,A,singleOsideband,transmitted,signal,consists,only,of,the,upper,or,the,
lower,sideband,and,no,carrier,is,transmittedD,The,elimination,of,the,carrier,from,the,AM,
signal,helps,to,eliminate,the,biggest,cause,of,whistles,and,tones,heard,on,channels,which,
make,even,moderately,strong,AM,signals,unreadableD,AlsoW,SSB,takes,only,half,of,an,AM,
channelW,therefore,two,SSB,conversations,will,f t,into,each,channelW,expanding,the,xb,AM,
channels,to,%b,SSB,channelsD,The,reduction,in,channel,space,required,also,helps,in,the,
receiver,because,only,half,of,the,noise,and,interference,can,be,received,with,qbbg,of,the,
SSB,signalD,
An,SSB,signal,may,be,received,only,when,the,listening,receiver,is,functioning,in,the,same,
modeD,In,other,wordsW,an,upper,sideband,signal,:USBF,may,be,made,intelligible,only,if,the,
receiver,is,functioning,in,the,USB,positionD,If,a,lower,sideband,:LSBF,signal,is,heard,when,
the,receiver,is,in,the,USB,modeW,no,amount,of,tuning,will,make,the,signal,intelligibleD,The,
reason,for,this,may,be,understood,if,you,consider,that,when,modulation,is,applied,to,the,
transmitter’s,microphone,in,the,USB,modeW,the,transmitter’s,output,frequency,is,increased,
whereas,in,the,LSB,mode,the,transmitter’s,output,frequency,is,decreasedD,The,result,in,
listening,to, the,receiver,is,that,when,the,MODE,switch,is,in,the,proper,position,:either,
USBW,or,LSBFW,a,true,reproduction,of,single,tone,of,modulation,will,resultW,and,if,the,tone,is,
increased,in,frequency,:such,as,a,lowOpitched,whistle,a,highOpitched,whistleF,you,will,hear,
the,increase,in,the,output,tone,of,the,receiverD,
If,the,incorrect,mode,is,selectedW,an,increase,in,tone,of,a,whistle,applied,to,the,transmitter,
will,cause,a,decrease,in,the,resultant,tone,from,the,receiverD,Thus,when,a,voice,is,used,in,
place,of,a,whistle,or,toneW,in,the,proper,listening,mode,the,voice,will,be,received,correctly,
whereas, in, the, incorrect, modeW, the, voice, will, be, translated, backwards, and, cannot, be,
made,intelligible,by,the,voice,lock,controlD,When,listening,to,AM,transmissionW,a,correct,
sideband,is,heard,in,either,mode,since,both,upper,and,lower,sidebands,are,receivedD
Once,the,desired,SSB,mode,has,been,selectedW,frequency,adjustment,may,be,necessary,
in,order,to,make,the,incoming,signal,intelligibleW,the,CLARIFIER,control,allows,the,operator,
to, vary, frequency, above, and, below, the, exactOcenter, frequency, of, the, received, signalD,
If, the, sound, of, the, incoming, signal, is, high, or, low, pitchedW, adjust, the, operation, of, the,
CLARIFIERD,Consider,it,as,performing,the,same,function,as,a,phonograph,speed,controlD,
When,the,speed,is,set,too,highW,voices,will,be,highOpitched,and,if,set,too,lowW,voices,will,
be,lowOpitchedD,
AlsoW,there,is,only,one,correct,speed,that,will,make,a,particular,record,produce,the,same,
sound,that,was,recordedD,If,the,record,is,played,on,a,turntable,that,rotated,in,the,wrong,
