We manufacture am fm radio receiver using cutting-edge technologies. The am/fm radio trainer kit has components placed over their corresponding symbols in the schematic drawing on the surface of the printed circuit board thereby maximizing the learning process and explain theory of operation of the radios. The radios are constructed in sections with each section being completely tested before moving on to the next, reducing difficult troubleshooting associated with some other kits. Trainer includes a high quality printed circuit board with schematic printed on the surface. The manual is easy to understand and assumes no previous electronics knowledge. The trainer kit of am fm radio receivers form a superheterodyne receiver of standard am (amplitude modulation) and fm (frequency modulated) broadcast frequencies. objective to study am radio receiverto study fm radio receiver nine sections audio amplifier circuitam detector circuit am if circuit am amplifier circuit am mixer and oscillator circuit fm detector circuit first fm if amplifier circuit second fm if amplifier circuit fm radio frequency stages. » am radio sectiontuning range520 khz - 1620 khzif frequency455 khztracking± 3 db from 700 khz to 1400 khz10 db signal to noise at 200 microvolt typical »fm radio sectiontuning range588 mhz - 108 mhzif frequency10.7 mhztracking± 5 db from 90 mhz to 106 mhzdetectoruses ratio detector and full time auto frequency control10 db signal to noise at 200 microvolt typical
