Building from scratch and from kits is alive and well in Amateur Radio as witnessed by the Web sites we visit this week.
Siniša Tasić-Tasa, YU1LM, is a QRP contester and radio homebrewer who began building ham radio receivers as a 13-year-old boy in elementary school. Ham radio receivers became his passion, electronics became his profession, and he has built some interesting radio projects during his career.
YU1LM has put together a Web page that documents some of the homebrew projects he has built, including a variety of software-defined radios (SDRs). Each project is documented with an Adobe Acrobat portable document format (pdf) file that includes schematics, block diagrams, printed circuit board layouts, parts placement diagrams and full descriptions of each project. "Projects are free only for personal use," he says.
These projects include a variable bandwidth XTAL filter, a tunable band-pass filter for all HF bands and a variety of SDR HF receivers, transmitter and transceiver projects.
TAPR Marks Quarter Century
 The TAPR Kits Web page features the current cutting edge projects of that digital innovator now celebrating its 25th year. |
In two weeks, the Tucson Amateur Packet Radio (TAPR) celebrates 25 years of digital innovation at the annual ARRL and TAPR Digital Communications Conference (DCC) in Tucson, Arizona where it all began a quarter-century ago. TAPR's two TNC (terminal node controller) designs (the "TNC 1" and "TNC 2") were the basis of virtually every TNC to see the light of day during the heyday of packet radio.
Today, TAPR is a digital innovator of a variety of projects on the cutting edge of Amateur Radio, such as the TAPR Vector Network Analyzer (VNA), the HPSDR project, which is an open source hardware and software project intended as a "next generation" SDR, the N4XI weather station kits, the Reflock II universal synthesizer and the N8UR TADD timing projects.
Until next time, keep on surfin'.

homebrewing, kit building and TAPR. To discuss parts, kits, and other neat
