The Adtron’s DSB / SSB AM Receiver Trainer is a versatile self contained stand alone unit useful in the study and demonstration of reception, DSB demodulation, SSB demodulation, and output amplifier. The unit consists of local oscillator, RF amplifier, BFO, Mixer, IF amplifier, detector audio output and speaker. The unit is housed in an elegant cabinet with a well spread intelligently designed circuit layout on front panel. Test points are provided at various stages in the circuit to observe the waveforms and voltages. It is strongly supported by a comprehensive instruction manual complete with theory and operating details.
