In Figure 3 of "Getting to Know Your Radio--VHF Squelch Modes" [August 2005, page 47] the correct URL for Communications Specialists is www.com-spec.com.
In "A Weather Vane Antenna for 2 Meters" [August 2005, pages 35-38], the loop polarization is horizontal, not vertical. While the antenna does radiate as a half-wave dipole, as the author notes, that dipole is parallel to the loop vertical axis but the E and H fields are interchanged, resulting in horizontal polarization.
In "Vibroplex Donation to W1AW" [August 2005, page 20], the group was actually from the Clark County Amateur Radio Club in Vancouver, W ashington. Dick, W7HUY, reports that the club will celebrate its 75th anniversary this month.
Clarification: In "ARRL at NAB" [August 2005, page 12], the booth team included members of several other area clubs: Frontier Amateur Radio Society, Las Vegas Repeater Association and the Nellis Amateur Radio Club.--Stan Perkins, W7SLP
Roy Dodge, VO1XP, took the July 2005 cover photo of the Marconi receiver.
The photo of the 1296 MHz dual quad-helix array, seen at the top of page 46 ["SETI: The Role of the Dedicated Amateur," September 2005], failed to identify the antenna's creator. This array was designed and built for The SETI League by Dr David Clingerman, W6OAL (Olde Antenna Labs of Colorado).--H. Paul Shuch, N6TX
Two symbols printed erroneously in Figures 1 and 2 of "A 20 and 40 Meter Vertical on Autopilot." In Figure 1 (page 28), L1 should be 2.6 µH, and in Figure 2 (page 29), L1 should be 5 µH.--tnx Van Field, W2OQI
