Allison used LT-Spice, a free circuit simulation tool, available from Linear Technology at:  http://www.linear.com/designtools/software/

For her PCB Prototypes, she used another free tool that is well integrated with the DigiKey parts catalog, called ExpressPCB.  This CAD software is used to capture a schematic and layout a PCB which is then produced in a few days by ExpressPCB (a set of 3 identical small boards costs $51, for example)

Coincidentally, the February 2015 QST had an article on rapid prototyping:  “Make Homebrewed Look Factory Built”.  That article also described using ExpressPCB, as well as other companies to produce metal enclosures and attractive front-panels.
