The Pizzicato Pulse Generator was designed by Gary Steinbaugh, PE, AF8L. His design appeared in the March/April issue of QEX. It is essentially a very low duty-cycle pulse generator that, according to Steinbaugh, “electrically â€œplucksâ€ a transmission line.” And, if you observe “the lineâ€™s reaction on an oscilloscope, you can check the lineâ€™s length, terminations, and possible defects.”
Bruce, KD8APB and I adapted this design, and in the process, making it easier to build. The Elecraft mini-modules served as the inspiration for this version of the design. KD8APB did most of the design work on this version, selecting the tools and doing the board layout.
We originally designed the kit to be built at our club’s annual Construction Night. The thought occurred to us, though, that we should perhaps buy enough parts for 100 kits and sell them the way that the QRP clubs sell kits for their projects. If you want one, we have them. :) They’re $15 USD, plus $2 s/h in the U.S., $5 s/h outside the U.S. This kit should not take much more than an hour to build for the experienced builder, somewhat longer if you are inexperienced.
If you want more information about the Pizzicato, you can download the original article (if you are an ARRL member). You can also download a zip file containing our documentation. The files in this archive include:
* README.TXT – this file
* Pizzicato Assembly Instructions.doc
* Pizzicato BOM.txt – the bill of materials
* Pizzicato Schematic.bmp – a bitmap of the schematic
The .pcb and .sch files are the CAD files for the printed circuit board and schematic respectively. To view and use these files, you will need the free CAD software from ExpressPCB, the company we used to make the boards for us. You can find this software on the ExpressPCB website.
