August 2005 QST Feedback
The site of the Missouri State Convention [see August 2005
QST, page 86] has changed. The new site is the Ashland Optimist Complex
in Ashland, Missouri, 13.5 miles south of Columbia on US 63. For details, see
the Central Missouri Radio Association Web
site.
The reference to military ARC-5 transmitters in "The
Doctor is IN" [July 2005 QST, page 54] isn't quite correct. The BC-457,
458 and 459 transmitters were not, strictly speaking, ARC-5s. They were part of
the SCR-274N Army Air Corps radio system. The ARC-5 transmitters were part of a
Navy radio system series (the T-15 through T-22).--Tnx Dean Billing, WA6IKJ
In "The Transatlantic on 2200 Meters" [July 2005 QST,
page 45], parts of equations 1 and 2 did not print. The equations should have
read:
L = 1/2πf2C [Eq 1] and
Rg = P/I2 [Eq 2]
