STAGE DR ASSEMBLY:
In keeping with our "learn-as-you-build" kit building philosophy, we will install
only the components needed for receiving.
Be very attentive to capacitor values (in picofarads) and to coil descriptions
throughout this section.
DR1. Correctly identify and install PIN diode D6. It is the only BA479
used in the circuit, and its number is stamped plainly on the diode body.
Be sure to orient the cathode end correctly!
DR2. Install L17, 2.2 uH in upright position with the inductor's body in the
designated hole. This is a molded inductor, resembling a resistor but is
larger. Look for 2 red bands on its body.
DR3. Because it must dissipate slightly more power, resistor R54 is
larger than most of the resistors used in this circuit. Its value may be 200
or 220 ohms (red-black-brown, or red-red-brown). Install R54 in upright
style.
DR4. Install C47, .001 uf (marked .001 or 102).
DR5. Install R28, 470 ohms (yellow-violet-brown).
DR6. Install C27, 100 pf (marked 100 or 101).
DR7. Install D4, type 1N914 or 1N4148. Orient the cathode band
correctly.
DR8. Install C53, .01 uf disc capacitor (marked .01 or 103).
DR9. Install C18, .001 uf (marked .001 or 102).
Install the following resistors, each in upright position:
DR10. R16, 22K ohm (red-red-orange).
DR11. R17, 270 ohm (red-violet-brown).
DR12. If you think that transistor Q3, type NE021, is tiny, wait until you
install C75, the SMT (Surface Mount Technology) or "chip" capacitor at
Q8, the Transmit Final Amp! Study the drawing and Q3 itself before
removing the device from its protective paper.
DR12b. The longest of the three
leads is the collector, which points to
R17, as pictured. Remove Q3 from
its adhesive paper, bend all three leads down 90 degrees, and insert as
illustrated.
