It is easier to download and install CalswrSetup.exe
This installs the Calswr program structure, help screens, documenetation and
the Picswr pic code.
All the files below are then to be found in C:\Program files\G3VPX\Calswr\hardware
Layouts and
schematics are produced using Pad2Pad which is a PCB layout program.
The .pcb files can be edited if you download a free copy of Pad2Pad.
The .pdf files were generated by printing from Pad2Pad to Adobe Distiller which will generate
PDF files from any printer output stream.
