Readme.txt for MURPHY0901.ZIP MURPHY0901.ZIP contains files pertaining to "The Q of Single-Layer, Air-Core Coils: A Mathematical Analysis," by George Murphy, VE2ERP (QEX, Sep/Oct 2001, pp 33-37). At the time of this posting, the author's e-mail address is ve3erp@encode.com. The files you have downloaded are antenna description files (.ez) and data tables for radiation-pattern plots (.ent) for the EZNEC and EZNEC2 antenna modeling programs by Roy Lewallen, W7EL. The files have no value unless you use that program or another that can read its files. (I don't know if one exists.) The files are supplied so that readers who want to duplicate or extend the author's work may do so. EZNEC is the modeling program we at HQ use. 73, Bob, KU7G 12:06 PM 09/11/2001 Robert J.
