Test and Measuring Instruments
OMEGA TYPE DB-30 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.Trainer forms a “Superheterodyne”
receiver of standard AM (amplitude modulation) and FM (frequency
modulated) broadcast frequencies.
