October 2009 QST Feedback

In “Hamspeak” [Aug 2009, p 103] the correct explanation of Horizontally polarized is — Orientation of wave front in which the electric field is horizontal.

In the 2009 “January VHF Sweepstakes Results” [Jul 2009, pp 80-83], the Nacogdoches ARC was inadvertently placed in the Local Club category. They are a Medium Club. The winner of the Local Club category is the Eastern Connecticut ARA.

In our Short Take review of the PIEXX SO2Rxlat USB to Serial Translator [Aug 2009, p 59], we incorrectly stated that microHAM America, LLC was a subsidiary of microHAM, s.r.o. of the Slovak Republic. This is not the case. microHAM America, LLC is an independent dealer. Also, the microHAM Control Protocol is the intellectual property of microHAM, s.r.o. and is available only to authorized application developers. Finally, the SO2RXlat without a case or display sells for $85; the model with the case but no display sells for $105.
