This template package contains the following files referenced in the 3CX1500D7 
RF Linear Amplifier project by Jerry Pittenger, K8RA, published in Chapter 18 of 
the 2006 ARRL Handbook.

24V PS Final.pcb
PS Rectifier Board Final.pcb
RF Control Board Final.pcb
Pi-Calc Ver 2.0.xls

The .pcb files are PC board layouts for the three printed circuit boards used in 
the amplifier. As described in the article, these files were created with a free 
layout program called ExpressPCB available at www.expresspcb.com. You must download 
and install a copy of ExpressPCB to view these files.

The ExpressPCB Web site has information about ordering these boards in small quantities, 
or you can make your own boards using by printing the artwork and using the iron-on transfer
technique as described in the article and in Chapter 8 of the ARRL Handbook.

Pi-Calc is an interactive Excel spreadsheet that the author used to calculate the Pi-L 
network values used in the amplifier and detailed in Table 18.7
