December 2008 QST Feedback
In “The Universal Keying Module” [Nov 2008, pp 43-45], Figure 1 has two errors. Pins 1 and 2 of U1 are reversed and Q1, a PNP transistor as indicated in the parts list, is incorrectly shown in the schematic with the symbol for an NPN transistor.
The DXLab Web site [Oct 2008, p 60] is www.dxlabsuite.com.
In “A Wireless PTT Switch for Mobile Operations” [Nov 2008, pp 73-75], the part number for the garage door receiver described in the text of the article is a Multicode 109950, instead of the GRD 1-channel Delta-3. Although they appear identical, the GRD 1-channel Delta-3 will not work with the specified transmitter.
Clarification: In “Product Review — GAP Hear It Speaker” [Nov 2008, p 50], Table 5 indicates that the audio output power was not tested. Our lab measurements are made from available access points on the equipment, and the GAP has no external speaker jack. Thus, we were unable to take that data without modifying the unit.
The Executive Committee of IARU Region 2 met in Panama City, Panama in late August. “In Brief” [Nov 2008, p 12] gave Lima, Peru, as the location. The 2009 meeting is scheduled for Lima.
