     The referenced article appears in the July/August 1998 
issue of QEX magazine, a forum for communications 
experimenters, published by the American Radio Relay League 
(ARRL), 225 Main St, Newington, CT 06111, USA; e-mail 
qex@arrl.org.

     The Zip archive containing this file also contains 
several files to facilitate production of etched circuit 
boards used in the project described in Francesco's QEX 
article.

THE AUTHOR'S FILES
     The following files are the author's data files and a 
DOS program to print patterns on Laserjet or equivalent 
printer connected to the first parallel printer port. To use 
these files, get to a DOS prompt and type

     PRINTPCB filename

where "filename" is the file to be printed, eg,

     PRINTPCB PCB93092.WBR

prints a pattern that includes *both* PCB1 and PCB2. The 
advantage of these files is that they print the patterns 
directly at the correct size.

     PCB93092.WBR      PCB1 (right) & PCB2 (left)
     PCB93111.WBR      PCB3
     PCB95061.WBR      PCB4
     PCB95021.WBR      PCB5
     PRINTPCB.EXE      DOS executable to print *.WBR files

AN ALTERNATIVE METHOD
     The author's process does not work on my computer, but 
I've found that common with DOS-based applications on my 
system. (Compaq Deskpro running Win95 served by an HP 
Laserjet 4/4m connected to the second printer port across a 
Novell network). Therefore, I've also enclosed 
high-resolution scanned images of the PCBs.
     To print an etching pattern using these files, open the 
file in a paint program that lets you vary the size of the 
printed output (Windows Paint does not). For example, JASC's 
Paint Shop Pro (for Windows) lets users set the output width 
and maintain the image's aspect ratio. Setting the output 
width to 4.74 inches produces properly sized patterns on my 
system. (Be sure to verify the board size on the printed 
images.) The correct size is listed, in millimeters and 
inches, on the "DIMENSIONI" line above each printed pattern.

FOR YOUR INFORMATION
     For the reader's convenience, I've included 
high-resolution bitmaps of the parts-placement diagrams that 
appear as Figures 5, 6, 7, 9 and 11 in the article. When 
displayed with a viewer having a zoom feature (such as Paint 
Shop Pro) these files may be easier to read than the 
figures in the article.
