9. Disconnect power and proceed with completing the transmitter section
(Steps TX15, etc.)
IMPORTANT: If you do not achieve the test results discussed above, there is
no point in doing more work on the transmitter section until the problem is
solved. If you are not able to transmit at least within the same room and
receive on any desired frequency, finishing the transmitter is not going to fix
the problem.
CONTINUE TRANSMITTER ASSEMBLY:
TX15. Install RF choke L19 (prepared in Stage TC), notice that the holes
are diagonal from each other. If the choke was wound correctly, L19 will
line up nicely as illustrated.
TX16. Coil L16, 1.5 turns, was also prepared in Stage TC. Insertion may
stretch the windings very slightly. Gently press L16 in as close to the top
of the board as possible, leaving about 1/8" clearance. The coil windings
must not, of course, touch the solder plane.
TX17. Install C61, .001 uf.
TX18. Install C66, 15 pf.
TX19. Referring to step TX16 and Stage TC as needed, install L15, a .5
turn coil.
TX20. Install L18, a .33 uh inductor with axial leads. (L18 looks like a
resistor body with wire wrapped around it and is marked by 2 orange
stripes).
TX21. Install R45, 220 ohms (red-red-brown), R45 is larger than the other
resistors in your kit, it is a 1/2 Watt resistor.
TX22. Install L14, .015 uh, .5 turn coil.
TX23. Install C60, 220 uf electrolytic, observe polarity.
TX24. C58, the last .1 uf capacitor.
TX25. C59, .001 uf.
TX26: L13, 1.5 turn hand-wound coil. Review "TC" and TX16.
TX27: C55, .01 uf.
TX28: C74, 35 pf trimmer.
TX29 C84, 20 pf trimmer (white ceramic body).
TX30: C64, .001 uf.
