Feedback - July, 2004 QST

The following corrections need to be made to "The Ten-Tec 6 Meter Transverter on 12 or 17 Meters" [June 2004, Table 1, page 41]. Change the following parts values: C8, 12 meters--1500 pF; add C10, C11--150 [100] pF; change C15, 12 meters--100 pF; C16, 12 meters--100 pF; C40, 17 meters--[100] pF; L7, 12 meters--0.68 pF. The part number for L15, 17 meters, should be [M8033-ND]. In addition, L3 is no longer available as a Toko part. It is now wound on an L43-2 Amidon core and Reference 1 should now read: "Wind 25T [19T] close spaced 36 gauge enameled wire on an Amidon L43-2 form. Use a drop of Q-Dope to secure the winding. Cut off the three pins not used." The schematic diagram [Figure 1, pages 42-43] should be likewise corrected.

In Figure 13, page 38, and the text on page 39 of "A 75 foot Top Loaded Vertical Antenna" [June 2004] the 3.51 MHz impedance should read 64.7 + j76.6 ©. The 765 pF capacitor should be shown at the right edge of the 3.2 µH inductor.

In Figure 5 (schematic), page 30, of "Give That Drake Receiver a New Lease on Life" [June 2004] U2 should have its "+" and "-" symbols reversed. The pinout is correct, however. In the parts list on page 32, relay K1 is manufactured by Omron, not Orion.

The large photo on the cover of the June 2004 issue was taken by Brenda Diamond-Rose, KB3ATI.
