INTRODUCTION, The Elenco Superhet 108C AM FM Radio Kit is a with an understanding of what that stage has been designed. superheterodyne receiver of the standard AM amplitude to accomplish and how it actually works After each. modulation and FM frequency modulation broadcast assembly you will be instructed to make certain tests and. frequencies The unique design of the Superhet 108 allows measurements to prove that each section is functioning. you to place the parts over their corresponding symbol in the properly If a test fails to produce the proper results a. schematic drawing on the surface of the printed circuit board troubleshooting guide is provided to help you correct the. during assembly This technique maximizes the learning problem If test equipment is available further measurements. process while keeping the chances of an assembly error at a and calculations are demonstrated to allow each student to. minimum It is very important however that good soldering verify that each stage meets the engineering specifications. practices are used to prevent bad connections The Soldering After all of the stages have been built and tested a final. Guide should be reviewed before any soldering is attempted alignment procedure is provided to peak the performance of. the receiver and maximize the Superhet 108 s reception. The actual assembly is broken down into 9 sections The capabilities. theory of operation for each section or stage should be read. before the assembly is started This will provide the student.

AMPLIFIER AMPLIFIER DETECTOR, OSCILLATOR, Section 5 Section 4 Section 3 Section 2 Section 1. The purpose of Section 1 the Audio Amplifier Stage is to signal Section 6 is the FM ratio detector circuit The FM ratio. increase the power of the audio signal received from either detector has a fixed gain of about 20 Section 7 is the second. detector to a power level capable of driving the speaker The FM IF amplifier The second FM IF amplifier is tuned to. audio amplifier is IC or transistor version Section 2 includes 10 7MHz Megahertz and has a set gain of approximately. the AM detector circuit and the AGC automatic gain control 20 The 3dB bandwidth of this stage should be approximately. stage The AM detector converts the amplitude modulated IF 350kHz Section 8 is the first FM IF amplifier The first FM IF. intermediate frequency signal to a low level audio signal amplifier is also tuned to 10 7MHz and has a set gain of. The AGC stage feeds back a DC voltage to the first AM IF approximately 10 It also has a 3dB bandwidth of 350kHz. amplifier in order to maintain a near constant level of audio at Section 9 includes the FM mixer FM oscillator FM RF Radio. the detector Section 3 is the second AM IF amplifier The Frequency amplifier AFC Automatic Frequency Control. second AM IF amplifier is tuned to 455kHz Kilohertz and stage and the FM antenna The incoming radio waves are. has a fixed gain at this frequency of 50 Section 4 is the first amplified by the FM RF amplifier which is tuned to a desired. AM IF 2 amplifier which has a variable gain that depends on radio station in the FM frequency bandwidth of 88MHz to. the AGC voltage received from the AGC stage The first AM 108MHz These amplified signals are then coupled to the FM. IF amplifier is also tuned to 455kHz Section 5 includes the mixer stage to be changed to a frequency of 10 7MHz This. AM mixer AM oscillator and AM antenna stages When the change as in AM is accomplished by heterodyning the radio. radio wave passes through the antenna it induces a small frequency signal with the oscillator signal The AFC stage. voltage across the antenna coil This voltage is coupled to the feeds back a DC voltage to the FM oscillator to prevent the. mixer or converter stage to be changed to a frequency of oscillator from drifting Each of these blocks will be explained. 455kHz This change is accomplished by mixing in detail in the Theory of Operation given before the assembly. heterodyning the radio frequency signal with the oscillator instructions for that stage. CONSTRUCTION, Introduction Turn off iron when not in use or reduce temperature setting when. The most important factor in assembling your Superhet 108C AM FM using a soldering station. Radio Kit is good soldering techniques Using the proper soldering iron Tips should be cleaned frequently to remove oxidation before it becomes. is of prime importance A small pencil type soldering iron of 25 watts is impossible to remove Use Dry Tip Cleaner Elenco SH 1025 or Tip. recommended The tip of the iron must be kept clean at all times and Cleaner Elenco TTC1 If you use a sponge to clean your tip then use. well tinned distilled water tap water has impurities that accelerate corrosion. Solder Safety Procedures, For many years leaded solder was the most common type of solder. used by the electronics industry but it is now being replaced by lead Always wear safety glasses or safety goggles to. free solder for health reasons This kit contains lead free solder which protect your eyes when working with tools or. contains 99 3 tin 0 7 copper and has a rosin flux core soldering iron and during all phases of testing. Lead free solder is different from lead solder It has a higher melting Be sure there is adequate ventilation when soldering. point than lead solder so you need higher temperature for the solder to Locate soldering iron in an area where you do not have to go around. flow properly Recommended tip temperature is approximately 700OF it or reach over it Keep it in a safe area away from the reach of. higher temperatures improve solder flow but accelerate tip decay An children. increase in soldering time may be required to achieve good results. Soldering iron tips wear out faster since lead free solders are more Do not hold solder in your mouth Solder is a toxic substance. corrosive and the higher soldering temperatures accelerate corrosion Wash hands thoroughly after handling solder. so proper tip care is important The solder joint finish will look slightly. duller with lead free solders Assemble Components, In all of the following assembly steps the components must be installed. Use these procedures to increase the life of your soldering iron tip when. on the top side of the PC board unless otherwise indicated The top. using lead free solder, legend shows where each component goes The leads pass through the.
Keep the iron tinned at all times corresponding holes in the board and are soldered on the foil side. Use only rosin core solder, Use the correct tip size for best heat transfer The conical tip is the. most commonly used DO NOT USE ACID CORE SOLDER, What Good Soldering Looks Like Types of Poor Soldering Connections. A good solder connection should be bright shiny smooth and uniformly.
