2.4 MICROPHONEAttach the microphone connector to a suitable microphone,as shown in Figure2-1. Be sure the microphonePTT switch is separatefrom the microphonecircuit, asshown. lt should be noted that a microphonewith a 3Pplug usinga common groundterminalshouldnot be used.The microphoneinput is designedfor 50OO - 50kO microphones. The choice of microphone is important forgood speechquality,and should be given seriousconsideration. The crystallatticefilter in the transceiverprovidesallthe restrictionnecessaryon audio response,and furtherrestrictionin the microphoneis not required.lt is more importantto havea microphonewith a smooth,flat responsethroughoutthe speechrange.Follow the microohone manufacturer'sinstructionsforconnectingthe microphonecableto the plug. With manymicrophones,the push-to-talkswitch must be pressedtomake microphoneaudioavailable.For VOX operation,thisunwantedfeature may be eliminated,if.desired,by opening the microphonecase and permanentlyconnectingthecontactswhich controlthe microphoneaudio.Standard microphonesensitivity is within the range of- 5 0 d B t o - 6 0 d B . l f a m i c r o p h o n eh a v i n ga h i g h e rs e n sitivity is used,the ALC and compressorcircuitswill notfunctionproperly.In this case,insertin the mike linean att e n u a t o ra s s h o w n i n F i g .2 - 1 c . A t y p i c a lM I C g a i nc o n t r o lsetting is 12 o'clock. lf you must run this control at I o'clock or less,use an attenuator.2.5 KEYlf CW operationis desired,connecta key to the KEYjack.U s e s h i e l d e dc a b l e ,a n d a s t a n d a r d( m o n o o r 2 P ) p h o n eplug.2.6 EXTERNAL SPEAKER ANDHEADPHONESReceiveaudiooutput from the TS-530 is 1.5 watts at 4 to16 ohms. The TS-530 has a built-inspeakerjack on therear panel. The speaker may be an 8-ohm permanentmagnet type, 4 inchesor'larger. The internalspeakerisdisconnectedwhen an external speakeris used. Head'lphones should also be 4 to 6 ohms impedance orgreater. When headphonesare connectedto the frontpanelPHONESjack,the speakeris disabled.2.7 GROUNDTo oreventelectricshock,and reducethe possibilityof TVIand BCl,connect the transceiverto a good earth groundthroughas short and heavya leadas possible.2.8 ANTENNAAny of the common antennasystemsdesignedfor use onthe high frequencyamateurbands may be used with theTS-530 providedthe input impgdanceof the transmissionline is not outsidethe capabilityof the bi-outputm3tchingnetwork. The transmissionline should be coaxialcable.An antennasystem which shows a standingwave ratio ofl e s st h a n 2 : 1 w h e n u s i n g5 O o r 7 5 o h m c o a x i a tl r a n s m i s sion line,or a systemthat resultsin a transmissionline input impedancethat is essentiallyresistive,and between15 and 2OO ohms will take power from the transceiverwith little difficulty. lf openwire of balancedtype transmissionline is used with the antenna,a suitableantennatuner with balunis recommendedbetweenthe transceiverand the feedline. Methods of constructionand operatingsuch tuners are describedin detail in the ARRL AntennaHandbook,and similarpublications.For operationon the1 6 0 , 7 5 a n d 4 O m e t e rb a n d s ,a s i m p l ed i p o l ea n t e n n ac, u tto resonancein the most used portion of the bands,willperformsatisfactorily.For operationof the transceiveronthe 10, 15 and 20 meter bands,the efficiencyof the station will be greatly increasedif a good directionalrotaryantennais used.

1.1 KENWOOD TS-530 The TS-530 is highly sophisticated solid state Amateur band transceiver employing only three vacuum tubes. Operating on all Amateur bands between 1.8 and 29.7 MHz, this unit is constructed modularly. The TS-530 in-cludes many built-in features usually found as extras on other transceivers. Included are VOX. 25 kHz calibrator,
