Rudolf Graf and William Sheets have written a book containing twenty low-power (LP) transmitter projects, perfect for the electronics hobbyist and radio experimenter. Now that the FCC has changed its regulations about "pirate" transmissions, more and more people are setting up radio and video stations for broadcast from their homes. Build Your Own Low-Power Transmitters addresses applications for hobbyist broadcasting of AM, SSB, TV, FM Stereo and NBFM VHF-UHF signals with equipment the reader can build himself for thousands of dollars less than similar equipment sold on the retail market. The authors also fully explore the legal limits and ramifications of using the equipment as well as how to get the best performance for optimum range. The key advantage is referencing a low-cost source for all needed parts, including the printed circuit board, as well as the kit. Projects in the book include: LP FM stereo transmitter; digitally synthesized PLL FM stereo transmitter; LP AM transmitter for 150-1710 KHz; radio control transmitter/receiver; carrier current transmitter and AM and FM receivers; LP VHF one-way and two-way audio links; 1-watt 40-meter CW transmitter for ham radio use; SSB LP transmitter for 10-meter ham radio use; 2-meter VHF FM ham radio transmitter; FM video link for 900 MHz NTSC/PAL operation; 2-watt TV transmitters for 440, 900 and 1300 MHz amateur TV NTSC/PAL transmissions; linear amplifier for 440MHz, 10-15watt NTSC/PAL operation; Downconverters for 440, 900 and 1300 MHz with VHF channel 3 or 4 output; TV video receiving systems and AM-FM IF systems; LP video link for UHF channels 14-18; 1-watt CW transmitter for Part 15 LF radio experimentation; CW identifier for transmitters; test equipment projects for LP transmitters; as well as an RF power meter and modulation monitor.

QRP continues to be one of the more active segments of the amateur radio hobby. Different people are drawn to QRP for different reasons but, for many, part of the fun is in building and learning. The oscilloscope is an affordable and useful tool to helping learn more about how (or if) your QRP transmitter is working. Because of that, the questions, ...
The RSGB (Radio Society of Great Britain) VHF-UHF Manual is must reading for the VHF and UHF enthusiast. You'll find information on the history of VHF/UHF communications, propagation, tuned circuits, receivers, transmitters, integrated equipment, filters, antennas, microwaves, space communications, and test equipment Use it as a guide to the theory ...
Originally published by the Radio Society of Great Britain, the projects were all chosen to be useful and straightforward, with the emphasis on practicality. In most cases the workings of the circuit are described, and the projects are backed up by small tutorials on the components and concepts employed.
