Welcome Friends!

The QRP/SWL Homebuilder site is owned and maintained by VE7BPO. The purpose of this web site is to promote experimentation with relatively simple and fun electronic circuits using scratch homebrew techniques. The site is targeted towards hobbyists. Excessive math, complex measurements and obscure parts are purposely avoided. The more qualitative aspects of electronic experimentation is emphasized as opposed to designing only via evidence-informed, scientific methodology. Certainly, good designs and techniques are promoted and used as possible, however, they are actualized more than developed on this basic or "popcorn" web site.

Please keep in mind that I am a novice, lay person experimenter and not an electronics engineer. Content includes Short Wave, HAM radio, some general electronics and guitar amplification experiments.

My special thanks to Wes Hayward, W7ZOI for his generous support and elmering over the years.

EMRFD is the official reference book of this web site.

Although, all the circuits have been built and tested and schematics drafted as carefully as possible, please accept that there maybe errors in the material presented. No liability arising from the application, use, or misuse of these projects that results in direct or indirect damage or loss is assumed.

Full price is paid for all of the parts I use and no monies are or were received for promoting any products or companies on this web site. Any ads, hyperlinks or mention of commercial products or companies is out of courtesy only.

Information Regarding the Compression of Schematic BMP Files

I see many electronics web authors compressing black and white schematics as jpg files. This results in distortion of the schematic. Schematics are best compressed using the 8-bit, lossless LZW algorithm which means converting the file to a .gif, .png or even .pdf format. The files sizes will typically be smaller than .jpg compression, have no distortion and can be edited easily. Thank you.
