This completes stage 2 construction of the VEC-1320K
20-meter kit.
After
checking for errors, you may now move on to the final stage of construction.
VEC-1330K 30-Meter Transceiver Kit
!
!
1. Find the 3.3 pF disc ceramic capacitor (3.3). Install at C13 and solder.
!
!
2. Find the 22 pF multilayer capacitor (22 or 220). Install at C15 and
solder.
Find two (2) 47 pF multilayer capacitors (47 or 470).
!
!
3. Install a 47 pF at C18 and solder.
!
!
4. Install a 47 pF at C2 and solder.
!
!
5. Find the 100 pF multilayer capacitor (101). Install at C25 and solder.
Find three (3) 330 pF multilayer capacitors (331).
!
!
6. Install a 330 pF at C14 and solder.
!
!
7. Install a 330 pF at C27 and solder.
!
!
8. Install a 330 pF at C28 and solder.
!
!
9. Find the 470 pF multilayer capacitor (471). Install at C23 and solder.
!
!
10. Find the 680 pF multilayer capacitor (681). Install at C24 and solder.
Find two (2) 2.2 uH molded chokes (red-red-gold-silver or gold)
!
!
11. Install a 2.2 uH at L2 and solder.
!
!
12. Install a 2.2 uH at L3 and solder.
!
!
13. Find the 3.3 uH molded choke (orange-orange-gold-silver or gold).
Install at L1 and solder.
Locate two T50-2 toroid coil forms (½" donut-shaped form, red color code).
Also, find the #22 enameled coil wire provided with your kit.
!
!
14. Wind twenty-five (25) turns of #22 enameled wire onto the T50-2
form. Note that turns are counted
inside
the form, and each turn is
pulled tight before winding the next. Spread the windings out,
distributing over 80% of the form's circumference.
!
!
15. Trim each coil lead to ½" in length and tin with solder.
!
!
16. Wind a two-turn secondary link of hook-up wire over the center
portion of the primary winding (two turns passing through the center).
