Feedback - May, 2004 QST

Experiment #12 of "Hands-On Radio" [Jan 2004, Figure 2, page 62] should show Vo with its "+" sign at the bottom of R1 and referenced to ground. This will then be consistent with Equation 2.--tnx Jason Dugas, KB5URQ

In Experiment #15 of "Hands-On Radio" [Apr 2004, page 71], Equation 3 should read E=1/2 LI2 and not E=1/2(LI)2.

In "The Skinny on Antennas" [Apr 2004, page 30], the formula for antenna length got transposed (second column, mid-page). The parenthetical factor should be (468/7.15), not (486/7.15).
